Robotic platform with large motors

Hi,

I am trying to build a large autonomous robot platform that is powered by the Jetson TX2. I have identified 48V 1600W brushless electric scooter motors (https://electricscooterparts.com/motors-my1020.html) for the powertrain with a 48V 1kWh battery pack. I am a little confused about the motor controller options that I can use with the Jetson TX2 to create a simple differential drive controller for the two motor robot. The electric scooter website has its own 48V controllers (https://electricscooterparts.com/speedcontrollers48volt.html) but I do not see any previous examples or documentation of this kind of controller being employed to control motors with the Jetson TX2. Please, Help!

Hi tyagi,
I’m not quite understanding your question. Which interface is employed to control motors on Jetson TX2? What’s the issue now?

Hi,

Thanks for getting back. I suppose I can rephrase my question to how do I select motor controllers compatible with the Jetson TX2? A lot of the examples focus on smaller motors with ESC units that are under or about 12V. I am seeking to run large 48V motors using commands from my Jetson TX2 any advice on how I go about doing that?

Apologies for the confusing question.

Hi tyagi,
For how to select motor controllers compatible with the Jetson TX2, just to want to make sure the interface is compatible.
(I think most motor controllers are PWM control.)
Jetson TX2 provides several PWM interfaces. Please check datasheet or design guide for detail.
