Hoverboard wheels + ODrive board + Arduino/Pi for ROBOT


#1

Want to power two hover board wheels on a medium sized robot.
I have done testing controlling from my mobile a Remote control car with mods but now I move up to the big boys hub motors from a hoverboard and realise i need to obtain a controller fit for purpose.

I assume this ODrive board does this so long as I drop voltage from 36 back to 24v. Im not super technical and know about enough to get me in trouble.

If i purchase this board can I attach the hoverboard wheels, a 24v battery, and download an adrduino sketch (or Python code for Pi) which will allow me to control these two wheels using a browser / mobile phone etc?

looking for a solution suited for people (like me) that should know better than playing with code and electronics :0) Ideally someone has done something similar and can share / sell me code. end game is being able to control robot with mobile phone and view POV from camera on robot.

cheers…

i am working on something very close.
you can order 48v odrive boards. at least that’s what i did and should receive them soon.
one key question is: will i need some extra encoders or will the support of hall effect sensor (already available in the hoverboard motors) provide enough precision for my usecase of an avg…

we’ll see

I am in the same position as you guys. I just need a confirmation that a hall effect sensor will work?


#5

you running pi or arduino ?

Hi Trash pilot, You and I are in the same boat. I have. A few projects that would work great on this board. I just need to confirm it was tested on hallsensore commutation.

@trashpilot and @alexisdal and @mac_patel which hoverboard motors are you using? I got this one: https://gotrax.com/shop/hoverboards/hoverfly-eco/

no clue. It says “gyroboard” on the – now disassembled – product. I bought it in france in a nearby store.
I can tell the wheel’s diameter is about 168mm diameter (6.5 inches?). All I know is that it’s exactly like oskar discribed in his excellent overboard motor teardown post (hoverarm project).
For the same price of delivered hoverboard motors, i had an entire hoverboard with a battery in it. For that money i was just happy to take the risk of ending up with a useless brick :slight_smile:

From Oskar:

[oDrive] can [read hull effect sensors], but that firmware isn’t generally released yet, I have to clean it up and document it. But yes it does work and we used it for the shopping cart demo.

Excellent… anyone want some cash to help me get something coded up ?


#11

Let’s definitely collaborate. See my DM
