One small suggestion for future missions: doing a loop course will stress the motors on one side a lot more, if you turned your waypoint mission into more of a figure 8 it would even out the work both sides are doing a bit. I love the idea of this bot just trundling around in a field all day, hope your Barbie gearboxes make things work!
I made a "battlebot" type robot with those kind of motors and won second place against much more sophisticated and expensive competitors. In the end, my choice of surplus, used batteries (batteries were not very affordable back then) is what failed and not the motor packs. I think the only reason that they were not commonly used back then was that they had non-standard drive outputs and 3D printers were not a thing. I ended up taking a welding class, specifically to make adapters for them.
Now if you add a metal detector and gps based mapping software that records each detection for you to go back and find the metal later-Then you have something! Something I invented years ago, you made it possible and automatic once this is perfected. Think of it: you could have this autonomously find metal in large areas, taking most of the leg work out of the equation. Excellent videos, I watch them all.
@@MABFR01 Another genius idea, also sellable, but for a life saving purpose. That is a multimillion dollar idea many large countries would use.. but surely it already has been tried
For marking, a solenoid controlled spray can, or small flags, fired into the ground, might prove simpler to manage as you don't have to use mapping. Pair that with a a random search pattern, and you'll have detection from multiple directions, to make detection more reliable. Leave in a field for a week, and check the markings armed with your pinpointer only. Could use different colors for ferrous and nonferrous?
I have done metaldetecting for years, and i can say this wont work like you said. You need to move detector side to side like once per second. That needs a motor system and causes wobble. Then, metal frame and wires will cause interfearance with the detector. Also, you really need to hear the signals from the detector by yourself so you can skip like nails and stuff like that. That come only with human experience. Cool idea tho
Man, I usually never comment on UA-cam, but I have to say I really look forward to each one of your videos. I really enjoy the content and all your effort! Keep it up!
What he should do is create and autonomous boat to launch and autonomous plane that drops an autonomous rover that launches and autonomous rocket into space.
Its hard to find custom tracks, 3d printers are really the easiest thing to make them, and I can be fiddly dealing with sprockets, harder then wheels, but yes your right, it needs them
If you separate the wheels and glue the tires to the rims with silicone you can drop the air pressure to almost 0, way better traction and a little bit of suspension
I want to make one like this with a mower attachment. I was thinking of adding steering to each wheel. If you could angle them in combination with the motor drive differential and avoid skid steering, it should improve traction.
@@tigeroll that design works fine for flat surfaces with predictable traction, but if one wheel falls in a hole or spins, there is no backup traction to get you out. My zero turn mower is made this way and it gets stuck on hills and wet grass easily. If a wheel starts slipping going down a hill, there is no way to steer it.
You can flash the firmware on the multi rotor esc to support bidirectional motors. Nearly all esc's can do it. Even tiny whoop drones can be flashed for 3d inverted flight.
Maybe ad some little feet actuators? Then if the program detects the GPS stays stuck in one spot too long, it could cycle those every now and then to lift the whole vehicle up and set it down again to try and get it un-stuck. Might help with the treads digging through the ground. Other than that, perhaps two sets of bogies and some free-spinning wheels that aren't driven to spread out the weight more? It'd end up looking more like some kind of rover yet. Also I don't see any problems with the new gearing. Just that the plastic it's made from could shear if it's loaded up enough. (Depends on what kind of traction those wheels could get.)
@@rctestflight do you think you could upload a video showing what gps and software you use, and how to set up the gps waypoint missions? Thanks in Advance
Hoverboard wheels with in-wheel motors are also very usable and reduce complexity. We're using them with two dummy wheels on the front and 2 wheel drive for our rover. Also, weight wise it might be good to use flexible solar panels.
Give it articulating steering then it will be unstoppable and you could even add a get unstuck option where it can drive and steer back and forth to “walk” out of a hole
Maybe use swivel casters for your front wheels, like power chair has... or entire power chair base, including motors / gearboxes (one I tested though has major disadvantage - too low, maybe 1" clearance above the ground).
Not sure if you are responding to posts, because I have a question about the 'autonomous solar rover'. ? Why did you choose the type of skid-steering versus other types of steering? I'm guessing it made it easier to follow the GPS way-points. I'm slowly working towards a GPS, FPV drone aircraft. I have some experience with rc planes and one helicopter. I have been accumulating some Arduino and Rasberri Pi boards, and associated parts. Also, I purchased a 3d printer in February, 2021. I have a ton to learn. I have some cnc, Bridgeport, and lathe experience. And a tiny bit of welding experience. I love the autonomous Tupperware boat. I saw a post regarding a company that offers drone support, especially when making delieveries. My 1st. thought was your videos and which direction you went in after graduating from college. 'Technology Demonstrator'. My ultimate goal is aircraft, but it would make sense to learn on the ground versus losing an rc plane, and more importantly, the electronics. Thanks for the videos, they have helped give me some direction, advice, and motivation.
how does the rover continue to do way point missions after you leave it and drive away? is your transmitter still at the field? if you turned your transmitter off wouldn't the rover go into failsafe mode?
What is the function of that little voltage regulator you are using, if it has the solar panels connected directly to the input you will have problems at sunrise, those buck regulators don't like slowly rising voltages on the input (sunrise), and will not startup.
With the barbie jeep motors being brushed motors, the esc needed is a lot simpler, a reprogramable BLESC could probably be made to run a BDC motor, but why bother when BESCs are cheap.
Looks like a lot of fun, but those motors and gearboxes sounded horrible! Has to be a better solution! 4 hoverboard hub motors with or without gearing? Make your own low kv motor and use hall effect sensors?
If those wheels on that rover are solid and not air filled, I would cut a paddle or lug style tread into them, so they provide great Driving grip in soft areas.
...so I designed an additional 3D printed cycloidal gearbox with a 13:1 reduction ratio that goes in series with the Barbie Jeep gearbox........ ooooofffff course ya did!! LOL. I'd expect you to 3D print a cold fusion reactor next to power the thing. Great job on this.
If you buy an old powered wheelchair and take off the seat you have a 'bogie' ready for about 15km of heavy work. Add the electronics...Im' in Ireland and already have one if you'd like to Co operate. I have lathe, milling machine fold and shear etc, so I can look after mechanical part.Joss in Cork, Ireland.
That's really cool! Maybe add more of those grips on the wheels, maybe 4 per wheel, and it will be pretty good I think. For the GPS mount wonder if having a little antenna tower would work too, though I guess it would cast a shadow on the solar panels.
This is awesome! Consider using wheels with grousers like the Mars rovers. Should work well on soft terrain. For a smaller rover this size I would increase the grouser size in comparison to Curiosity to like 2cm with a 10cm wheel diameter. A simple wheel like that should be 3D-printable as well!
You could prototype structural stuff a lot faster/easier with 8020 aluminum profiles probably, certainly less welding involved ;-) Love the concept though, definitely following.
havent watched the whole video yet, but if i was to do this, would a base of an RC offroad car be better? its light, quite strong and affordable, has a motor, gearbox and front wheel steering
Have you considered using stepper motors instead of gearbox motors? They have excellent low-end torque. You could make them direct-drive. Seems like it would be perfect for this application.
Hey i been watching your videos for a while and was curious if you had any updates with the electric scooters. Maybe a new ESC because in the link i cant find it
Hello!! Great build, can you please share some information about the chain and the pulley for the chain?:) I'm working on a different project but I really need some traction system
Can you use a regular rc truck ESC and connect it to AudruRover/Pixhawk? Also is it possible to program a RC truck ESC with a airplane receiver and transmitter? Thanks man keep killing it!

"I chose the cycloidal gearbox because it looks cool"
Yeah, that's basically how we all make decisions at this point.
That's just as fine a reason as any.
Man, I usually never comment on UA-cam, but I have to say I really look forward to each one of your videos. I really enjoy the content and all your effort! Keep it up!
Ikr, I'm so excited when he uploads
I looked through all my notifications and out of dozens his was the first I went to.
dnmwww.faithfreedom.org/Author/Sina.htm
Yeah, this is pretty cool!
You’ve got all 3 now: autonomous air, water, and now land vehicles
*SPACE*
Now to get the air to launch from and land on either of the other two.
What he should do is create and autonomous boat to launch and autonomous plane that drops an autonomous rover that launches and autonomous rocket into space.
Lava?
And all changed when the autonomous fire nation attacked...
As always, your projects are entertaining, enlightening, and inspiring. Just wish I were 50-years younger. Thank You for sharing your efforts.
Clemson!
What would the world be like today if we had the internet and you tube 50 years ago?
I need to lose 50 myself!
noise L
The absolutely coolest thing in this project was the 3d-printed cycloidal gearbox at the end. Really neat plug-and-play solution!
Should named the rover Perseverance II
Tracks... like from a tank. Also, use RC car ESCs for reverse.
Its hard to find custom tracks, 3d printers are really the easiest thing to make them, and I can be fiddly dealing with sprockets, harder then wheels, but yes your right, it needs them
Would not track be prone debris?
Tracks are better to traverse any terrain, but they require more frequent maintenance.
just clicked on this dudes channel and the video was uploaded 40 seconds ago bruh
And you didnt feel the need to say 'first!' like a fkn child. Man i hate those people. Good onya
you sir are my hero. ive wanted to build this exact thing for years. and you did it alone and cheap. nice work brutha. subbed
Now I want to make one. The idea of having a rover doing it's thing is so cool
This guy is like "hold my beer, NASA"
always pleased to see one of your videos is up..
If you separate the wheels and glue the tires to the rims with silicone you can drop the air pressure to almost 0, way better traction and a little bit of suspension
Very cool project. I like seeing all the failure points and the steps you take to overcome them.
you are my ACTUAL favorite youtuber
Hey man, thanks for providing something to watch. I'm quarantined at home right now. Thank you! Stay healthy!
You could try and re flash the motors esc to receive the rc pwm signal.
I think that gearbox is the coolest thing I've ever seen 3D printed
Nice work, looking forward to the next episode 👍
I want to make one like this with a mower attachment. I was thinking of adding steering to each wheel. If you could angle them in combination with the motor drive differential and avoid skid steering, it should improve traction.
I'm collecting materials to do the same. I was thinking of 2 drive wheels and 1 swivel wheel, that way it can go back and forth and change directions.

This has really super good basic and quality engineering. Thanks man!

Please make a video in which you explain how to setup the electronics for the waypoint missions
Would be great yeah.. Maybe on a second channel?
@@MABFR01 Why on a second channel?
He could make it on this channel´.
I´m sure there are many people which would like it!
Maybe ad some little feet actuators? Then if the program detects the GPS stays stuck in one spot too long, it could cycle those every now and then to lift the whole vehicle up and set it down again to try and get it un-stuck.

I don’t know if they’re made small enough for things like this, but a pair of treads would probably help traction and steering (also a lot cooler)
To you this may be like nothing but I cant tell you how impressive you are. I can not wait to see what you do every video. Just so impressive.
Since I started watching your channel, I am so impressed and PUMPED to try some of your builds!! Thanks!
For designing your cycloidal gearbox, where did you find your information on how the gear should be shaped?
ua-cam.com/video/jQ6LQBFZXmU/v-deo.html
@@rctestflight do you think you could upload a video showing what gps and software you use, and how to set up the gps waypoint missions? Thanks in Advance

Coolest video in a while, er, since your last video. KEEP IT UP!
Now you gotta find a 7-year old kid to name this one (if you understand the reference)
Make them write an Essay on why that should be the name
@@ronaldpm Better in what way? lmao! It's just a name dude.
7 year old Thesaurus searcher extraordinare wins Nasa award for choosing common word.., next on the 5 o clock news
U should add some sensors at the front to prevent it from ramming in any obstacles
I really like these autonomous projects :)
That wing at 4:47 is a prandtl d? can we expect an episode about it?
Can you explain how you wire up the Lipo battery’s to charge by the solar solar panels while they are being used by the rover?
Air, Sea, Land, what else do you want to master on autonomous vehicles? This is impressive, I love it!
Waiting for episode two! :) from Philippines
Me to frome ph

BLHeli ESC's can do reverse, just set to bidirectional.
Quality vid! Thank you for sharing this with us.
Really cool, you always create new entertaining project. Appreciate it 👍
Super cool video, Will be looking forward to the next one!
almost like you should've kept the built in ESC that actually had the features you needed
9:00 could you put less voltage through the barbie motor and it would run slower?
I love how you leave your projects to run and come back hours later
I liked this way more than I was expecting. Again, I don't know how you do it but you make these things super interesting.
this man out here making a mars rover in his garage
If you needed a servo-style PWM source arduino has a Servo support library.
Give it articulating steering then it will be unstoppable and you could even add a get unstuck option where it can drive and steer back and forth to “walk” out of a hole
Maybe use swivel casters for your front wheels, like power chair has... or entire power chair base, including motors / gearboxes (one I tested though has major disadvantage - too low, maybe 1" clearance above the ground).

holy shit man you can't just skip over that cycloidal gearbox! I've never seen that before and it looks insane!
I love that you used tupperware in this project as well!
EDIT: 2:00 YOU HAVE BEEN REPLACED
For enough power you can use boost converter
5:58 I thought he was about to start rapping...
I'm interested to know what flight controller you used for this, and if it's the same flight controller you use for your other autonomous projects?
Would you have a bit more information on setting the flight controller please ?
how does the rover continue to do way point missions after you leave it and drive away? is your transmitter still at the field? if you turned your transmitter off wouldn't the rover go into failsafe mode?
What is the function of that little voltage regulator you are using, if it has the solar panels connected directly to the input you will have problems at sunrise, those buck regulators don't like slowly rising voltages on the input (sunrise), and will not startup.
I wonder if you couldn't get a bit more traction on those wheels with a bit more weight
Nice work, looking forward to the next episode
What about caster type wheels in back? Drive wheels in front?
noob question : vesc instead of multi rotor esc ? My understanding is that they're better suited for ground vehicules, especially for slow starts
With the barbie jeep motors being brushed motors, the esc needed is a lot simpler, a reprogramable BLESC could probably be made to run a BDC motor, but why bother when BESCs are cheap.

Those are some excellent welding shots.
Need a video on that gear drive!
Yup.... Wanna see that new gear drives in action. Where did you get the Barbie Jeep Motors ???
How about using tank tracks? Way better traction and you only need 2 motors
If you buy an old powered wheelchair and take off the seat you have a 'bogie' ready for about 15km of heavy work.

Hello! Where did you find sprockets that match the harbor freight tire bolt pattern?
Add solar tracking to the panel so that it gets the most of the solar power
reminds me of coopers automated farming equipment in interstellar
Seems like tracks would be better suited to that type of ground. Less prone to digging in/ getting stuck.
Make it do automation. Add things like wind meters, humidity meters, and etc, to read before coming out to the field and so you can read at home/work
You could make this into some sort of grass cutting rover. It maybe slow, but it will do its job indefinitely.
rovers are nice. hoping to see more of this!
I really like these way point mission project videos!
Another interesting project... I look forward to part 2... 👍
I like him and his channel so much, man teaches us.
Why dont you spin one side in reverse when you're doing a turn ?
You should totally improve the wheel design on that Rover. You could even 3D print a set of Rover like Wheels, now it would really look like one
How many watts were the solar panels? Sorry if I missed it.
