Senior Robot help

Bought a XiaoR Geek Smart Robot car Chassis for my senior design project. We are supposed to level out rice in a big silo, and to do that we are putting a brush on the back. Currently I’m trying to figure out what kind of motor shield to use, also what kind of battery. The motor for the brush is a Greartisan dc 12v 100 rpm. The motors on the robot are 7-12 v and the motor speed is 160rpm. Thanks for any help.

Hey @sgewin

In order to suggest you motor controller, I’d need to know more about the motors. What is the rated current specifications exactly?
How will you be controlling the robot exactly? With a microcontroller? RC?
