$200US for someone to get my ODRIVE running with hover board motors

Support

Guys Im running short of time on this and need someones assistance.

So i have a 48V O’drive, a hover board battery and two hub wheel motors with hall sensors, a raspberry pi & camera

My end game is to be able to control this robot platform with remote control from an open source mobile app or web page over wifi.

let me know if anyone is interested… Im expecting someone has already done exactly this so its a quick job of sending your code to PI, configuring O’drive and giving it a whirl. i will provide team viewer, a mac with usb connecting with odrive tool and SSH to Pi… i’m not fussed about programming language, thats up to you.

Let me know if you’re interested.

Hit me up on the ODrive Discord.

Hi again odrive overlord.
Happy to say i have my odrive 3.5 48v and 2 hoverboards powering up beeping, doing calibration checks.

Im trying to achieve something simple as it seems small steps are more likely to get me results. So about 1000 years ago in the apple II era there was a program called logo… you used it to move a little turtle around the screen… im wondering if there is an easy way to send commands to my odrive in a similar fashion so i can then use dead reckoning to tell my robot to go say
fwd 50
right 90
fwd 200
left 50 etc.

Whats the best way to achieve this. I have PI or Arduino to control… ultimately i want to connect PI Camera so i can view where device is at will so pi would be preferred. Anyone out there have a script or some code i can drop in ?

Thanks again… I have some robot code which came off a remote control car which also had sonar and video, open source code is run on a raspberry PI. it has a simple app for android which allows you to control robot with remote control and view the camera as you move it. i want to replace the motor controller and associated code so that it can be replaced with the ODrive…

like all of these robots it has three py programs, one for avoidance, one to follow a line, the final one which allows remote control of the robot with webcam view… i figure the quickest is one of the simplest so i have attached…

how difficult is it to get this to a base case working code for odrive and hoverboard wheels ?
