Hi, I am new to ROS and I am making an autonomous buggy scale 1:10.

I am trying to understand how to communicate with the Electronic Speed Controller (ESC) of the Buggy's DC motor. I have also checked the page: http://wiki.ros.org/Motor%20Controlle.... And my ESC is HW-WP-1040-BRUSHED, you can see it here: https://www.redcatracing.com/products...

I am using a Raspberry 3B+ with Ubuntu 16 and ROS Kinetic. I have already achieved the connection with the steering servo using an Adafruit servo board.

Any source I can read from is welcome.

Thank you.

So basically, I just tried the same PWM control for the servo but on the ESC. Have a look at this gits:

My ESC works in a very narrow range (340 on the pwm value means no speed, and 350 means top speed more or less).

I am going to try the proportional control offered in the first git.

Regards.
