Setup Motor Control #4

Open garethellis0 opened 7 years ago

garethellis0 commented 7 years ago

Once we've decided on how we want to move, we need to translate these commands into motor controls
On the computer side we will receive a twist message which is the movement command
We will need to convert this twist message to a serial message and pass it to the arduino

Possible Seperate Issue

The arduino will need to receive the serial command, and convert it electrical signals to send to the motors. This will depend on how the robot is wired.

Update

We need to try and repurpose our firmware from here to try and control the motor and speed controller for the smaller RC car

Dulluhan commented 7 years ago

RC cars just need 2 sets of pwm out. One for servo for steering, one for throttle. Pretty straight forward. The scaling can be 1-1 in this case converting from twist to servo out. No need to slow or speed wheel differential throttle.

Hmmm, we seem to be doing some mapping in the differential drive firmware we have for JFrost here. We can probably just toss this as well then? Just do the mapping on the driver side?
