But won't it affect the calculation if we augment the matrix by inserting 2 and 1? 3:54
Thanks
It's great that the hoverboard motors are so cheap, but what about the rest of the components? Is it possible to replace the odrive controllers with something cheaper? Or use hoverboard parts? I want to say thanks for all the work done
Isnt that 8040 rail? Or 4020
nice thankyou
Cool background music from Zelda!
dude a thousand thank yous because i have been needing info on this topic. and you are doing such a great job of explaining it. thanks for you hard work
how make uboot for allwinner h313 / 616 for boot and install linux in tvbox ? Thanks
any update on the build?
Currently fine-tuning the inverse kinematics for getting the motors to move the way I want based on object detection. Working on part 11.
@@AustinTronics ty
Thanks Austin, really appreciate your effort on releasing those vids
Good job 😊
Hey, great that you are back with the project, I had the same problems with the hall sensors, what worked for me was to go back to the old version of the firmware, I'm using 0.5.1 if I remember correctly.
I am surprised there is so much cogging on a hoverboard motor. Can odrive compensate the deadtime? This can help a bit but is not related to the position.
Really useful, nice detail as well thank you, look forward to next video. I am working on the CNC O-Drive project as documented on @Dev255 YT channel.
This is so cool. It’s great to see a project end to end like this keep making great content ❤
Heeeeyyy, been a while. Good to see an update.
I will be anxiously waiting for the next video about the encoder with greater precision. I am building a complete robotic arm and the best candidate to be the shoulder of the robot are the two Hoverboard motors with Odrive, the issue of precision is essential. I wanted to know what encoder you used in the video and which one you plan to use in the next one.
happy to see that you‘re back
it's good to see you again
woooooah you're back!
Hi Austin, Thank you for your hard effort and work on this series 🚀🚀 Are you considering finishing that project ?
Great work thank you for taking the time and explaining this setup. I was wondering i you have run an anti cogging on the hoverboard motors?
Oh, my bad i did check the script on github. I had to add a lit to ignore the illegal hall state error. How will this affect the control of the motor? Also, why does this happen for some hoverboard motors only?
Thank you for sharing such wonderful developing experience. It is really a great job. How come I didn't find it for the last three years.
i used a single diode on one phase and was able to get 28 volts of DC. Turning it 750 rpm or so. How was that possible?
can it be ran as a propeller at 1000 rpm. with a couple of propeller blades attached?
Nice video and demonstration. Xilinx/AMD are starting to transition to this device tree configuration approach which will replace the AMD proprietary tools used for the mdd, mld and mss files. While they don't use the DTC (although I think it works for the Zynq 700 Cortex A9 chips, such as the Zybo) they instead use their own version called the SDT (Systerm Device Tree) tool. Do you have any experience with automating builds with this approach opposed their old XSCT approach? Mainly for Standalone applications using FreeRTOS.
seriously fucking many thanks for the video - I was trying to get it to work for DAYS, read the documentation, etc... no success. The video helped me to get it to work which is... enormously satisfying! thanks!
Great content. Looking forward for more.
Great video - would the ODrive S1 controller, with the on-board encoder, also work in this case? What might be the pros and cons of one vs the other? Thanks!
could you show how to send it to the sd card, im using buildroot for imx6q sabre and i got a u-boot.imx and u-boot.bin, besides boot.vfat and zImage. I'm kinda lost, hope you see this comment
u-boot.bin typically goes inside a boot.bin archive file if your target hardware is a Xilinx (AMD) chip. The zImage is a form of kernel binary. You need the kernel in the form of image.ub so that the binary has the proper header information for u-boot to properly hand off execution control to the kernel inside the image.ub.
Can you make a robotic arm for quadriplegics.. my left arm / hand is c4 damaged with contracture .. my right is c5 damaged . No splints could ever be used . Not a amputee, have the limb in the way
Why not try a power wheelchair.. make it weather proof .. our joysticks bite & simply don’t hold up .. chargers melt the 3 pin connector on the joystick as so many are sold without a uL & get hot enough to melt .. batteries vary as much as the details not factual & misleading . I wouldn’t mind having a robo dog to be a service dog .. my dog died & I miss him dearly . This quad was made paralyzed by a device lacking a cervical patent .. I think it’s time technology help patients vs use our life to test what mfg’s had no data for & pressures of fda - they act as surgeons & a god while knowing the outcome is life changing adversely. Ty for the thought .. it’s nice to see the brain used. Oh, my Permobil c300 motor held well .. rovi motor perhaps ?
Using this playlist 8 years later to supplement my computer engineering degree (which didn't require me to take control systems) before I graduate in May. Thanks for leaving this up!
What type of actuator you are going to use..
I used to use a glue stick too, ended up switching to cheap hairspray and haven't had any issues since!
I use the flipsky vescs but they are expensive! Where do you get your motors from? Like can you buy them directly?
What's the maximum torque and weight of a hoverboard motor? For quadrupedal robot jumping, we can achieve around 40 cm jump height for a 9 kg robot assuming 18 Nm torque on some of the 12 quasi-direct drive actuators. My thinking is if hoverboard motors are so cheap and have such high output, and are backdrivable due to no gearing, then it would be great for legged robots.
Sir, How to make an debian based distro for ARM device?
You should look into using Yocto for that.
very nice. which driving board you have used.
This is pretty cool! Jw, Is the setpoint noisy or just the resolution of control? Im kinda of wondering since these motors are prob torqued accordingly to their application i.e. carry an adult or kid. Either resolution of encoder is too low or something else.
It's 100% the control. The X, Y, and Z of the image processing is pretty consistent. However, the motors are brushless and experience cogging because the spacing of the magnets are pretty wide. Cogging in brushless motors can be compensated for, and the ODrive motor controller I am using has a feature to compensate for that. However, it can only do so when the encoder has a fine enough resolution. I am using the built-in hall effect sensor that the hoverboard motors have and it's not enough resolution to compensate for brushless motor cogging. I plan on eventually upgrading the encoder so it has better control.
Predators tracking device right here. 😂 Great work!! I'm still tuned in.
Can I have the project repository?
What is this about with hoover board motors?
Do you plan to make a specific video on the implementation of a PID for a hoverboard motor? If so, you would be "man of the year", that's for sure.
Idk about a specific video, but I will talk about it in the next one I do. I didn't come up with an analytical approach, I just brute forced it. I wrote a script to sweep through PID values to find an optimal PID. I'll probably provide the script before I release the video on my GitHub.
@@AustinTronics Thank you very much.
I might want to discuss this on the simpleFOC forum also.
Are you using the hall sensors or did you fit encoders already?
@@candas1 I figured I would try to get things working the best I could with the built-in hall encoders so that I could do a comparison when I implement higher res encoders to ensure there really is an improvement in performance.
Fake
Please please restart this series of videos !! 🙏
It's must be really big dog. Or maybe robot bear😊
When is it ready?
If their is error in bit stream generation for system verilog program by writting verilog wrapper then what should I do for generating bit stream.
What is the purpose of this?
