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.

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.

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?

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.

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

@AustinTronics 5 ай бұрын

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

@luvaquad 6 ай бұрын

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 ?

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.

@imignap 11 ай бұрын

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.

@AustinTronics 11 ай бұрын

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.

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.

@AustinTronics 11 ай бұрын

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.

@@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.
