"I'm going to build this exact same bot."
*looks at instructions*
"Nevermind."
Do you get power to the receiver by getting + and - to the receiver through channel one? Thanks!
TML ProductionsTM the 5V to the receiver comes directly from the 7805 voltage regulator that I put inside
Thanks!
TML ProductionsTM And it the 5V supply can connect to any of the reciever channels, as long as you have the correct polarity
Thanks
How exactly to the drive motors get power? Thanks!
TML ProductionsTM the motors come with a three pin connector and cable. The green goes to the receiver, the red to your positive battery supply and the black to your negative supply. The motors are only good for 2S.
Adelaide Robot Combat Ah thanks! That is a big help. May need to get some.
These motors are a bit of a revolution to me I've been struggling to get esc small enough here in the uk, would you be able to give some information were You for them from or were I could get them from, I would like to say that your videos are a constant source of inspiration thank you !
Ah I'm such a noob I just read the full video description *face palm* thank you again
Adn Sizer No problem! And thank you!
How many RPM?
Theoretically 17000 rpm with this bot. The motor is 2300kv, so 2300x7.4V = 17020RPM
@@AdelaideRobotCombat I'm thinking of coming back with a new robot, so I'm learning all the terms. I was choosing ESCs for the robot but came upon DYS. What's DYS?
@@ethanli2045 DYS is simply a brand
@@AdelaideRobotCombat Oh, Thanks
Awesome work man! Hope you're venting those nasty acetel fumes somewhere :) Was it ABS for the middle of the frame?
Maker's Muse Yep ABS
Im from Russia, a like your videos! you are a good man. LIKE
Just wondering is the weapon supported by the top or the top and bottom
It supported by top and bottom. It's supported up top by the motor itself and on the bottom by a flange bearing
Any recent updates to Shrapnel? My kids and I are getting into the local 150g class and this looks great to try. Thanks.
Is that a laser cutter you are using there at the beginning??
Thanks
M.P Gaming Sure is, got access to a new Makerspace which has their own laser cutter.
I love the video and the shirt you're wearing!
I love this design. .
I never knew that shrapnel was 3D printed
I thought because of the weapon it would need something more than 3D printing so it doesn't kill it's self
3d printing is strong as fuck, and is light, so its kinda the perfect option for competitive designs
UB-420 MeMeLoRd based on what I have seen, anything from below a Pound in weight could benefit from 3D printing. Normally after that one pound in weight, 3D printing is one of the worst things to make a chassis out of, it even breaks under the strength of the weapon hitting other bots.
Evil Toaster have you tried different materials?
Like "dat guy" said, different materials hold up better than others. I've had a lot of success with Alloy910 and more recently Matterhackers NylonX (basically Onyx) in US Antweights, and there's actually quite a few Markforged US ants and even Beetles out there. I would NEVER use PLA on a US ant or bigger, though (and honestly I find it kinda suspect on a 150g bot).
Looks like carbide to me
british roice video Turned out pretty similar actually, lol
Cute baby carbide
This is so satisfying to watch and helps me with understanding the building process! Can't wait to build mine soon! Thanks for the awesome and soothing video!
How big is this version of shrapnel?
Tendrás un diagrama de las conexiones??
Have you considered making a single tooth disk for Shrapnel?
Rattler Robotics I haven't yet explored different weapon disks/bars for shrapnel. I've got one more modification (hopefully) and then I can look at some better weapons for it
Is the titanium weapon bar really better than an equivalent weight steel bar? Is it a vibration issue?
Douglas Butler For me going with a titanium bar was an easy solution to getting a very hard weapon bar without having to harden any steel.
I previously used a steel weapon bar but because it was never hardened it got damaged and bent very easily.
What transmitter do you use to bind to the receiver?
Jack Freemantle A DX6i
how is the LM7805 connected?
The Vin connects to the battery supply. The Vout connects to the 5V supply of the reciever and the common connects to the 0V of both the battery and the reciever. If you're ever unsure, look up a datasheet all the info is there
omg its a mini carbide

Could you make the laser cutting files and 3d printed model files available? If they already are, could you refer me to a link?
Arjun Mody Not available yet but I'm thinking about getting into it soon. There's a newer version of this recently finished and works ever better!
Adelaide Robot Combat ok cool. I'm going to be doing a competition in a month or two, and your design was pretty good.
So for then weapon did you use micro metal gear motor with driver or controller
Alex Germain Neither. It's all in the video and video description. A 1804 brushless motor and brushless ESC was used for the weapon in this version of Shrapnel.
Adelaide Robot Combat sorry I meant the drive
Alex Germain There's a link for the product I've used for my drive. It's a microgear motor with a controller built onto the back which receives the signal from the Rx.
What is the diameter of that bar?
90mm
What is the weight, also is it 3mm thick?
Yeah it's 3mm grade 5 titanium. It weighs just under 20 grams.
Looks great man, keep up the good work
Sploodle Thanks!
