Rapid motor switching

Hi

In general, with the PiBorg reverse and DiddyBorg motors, is it safe to switch the motor direction instantaneously? Or is it preferable to ramp the current from one level/direction to another? I'm thinking that there might be large current spikes if the voltage is reversed whilst the platform is in motion.

Best wishes
Kevin

When the motors are small enough (lower power) it does not tend to be a problem.
With the DiddyBorg motors you should be able to switch direction instaneously without any trouble.

Ideally ramping power is best in general and should avoid any spikes in voltage from any attached motors.
With larger motors than the DiddyBorg ones we recommend at least going to 'stopped' first before changing direction.
This is worth bearing in mind if you plan to get larger motors for a robot in the future.

Thanks.
