Best PWM motor controller for the Bogie Runt Rover

Help & Support Robot Parts

Hello everyone.
I’m starting to build a raspberry pi 4B powered rover. I’m using this project to teach me more about programing and hardware.
So far I’ve got a pan & tilt hat with the Pi camera & ultrasonic senser mounted. I’ve bought a Bogie Runt Rover and I’m woundring what is the best motor controller for it that has PWM?

Thankyou all in advance

Hi,

How do you plan on controlling your 6 motors?

You will send a command from the Raspberry PI or it will be remote controlled with R/C signal?

Hello

I was going to use commands from the RPi to control the motors.

Originally I was thinking of using three L293D motor controllers. This would work but I wanted to find a way to slowly change direction rather than having to wheel about a point. I wonder if it would be possible to use an arduino uno which has six PWM pins.

Hi,

Thank you for the clarification.

There exist some HAT that are made to drive motor.

Cytron has a good one: https://www.robotshop.com/en/cytron-2x10a-motor-driver-hat-for-rasberry-pi.html

HATs are compatible with raspberry pi directly.

Note that it is possible to output PWM from the Raspberry Pi GPIO: https://circuitdigest.com/microcontroller-projects/raspberry-pi-pwm-tutorial

I hope this helped you.
