I want to use four 47:1 Metal Gearmotors (#2274) with a VNH5019 shield (#2507).
In my project, the motors drive a vehicle with ~2 kg of weight, with wheels of ~12 cm diameter.
I occasionally want to use the max. speed this motor/shield combination can give (e.g. ‘setSpeeds(400)’ in the arduino lib).
To stop the vehicle, the shield allows for ‘coasting’ and ‘braking’.
Of course, i can also continuously lower the motor speeds to zero using the microcontroller.
Looking at the high gear ratio (and the tiny gear boxes), i wonder which stopping methods would be feasible, i.e. typically not harming the gears.
I fear neither ‘coasting’ nor ‘braking’ are safe here, but is this true ?
Are there other stopping methods i should consider ?
Any hint/advice appreciated
