I'm wondering if, were I to buy a Rover 5 chassis with only two motors and encoders, would I be able to buy two more motors (and their gearboxes, with or without encoders) separately, later on, to upgrade it to a four-motor chassis?
With the treads, two motors is probably all it needs, one for each side. But I understand the treads can be removed, and ordinary RC car wheels put on. Then it would be handy to have 4-sheel-drive, especially if each separate wheel were independently controlled by the microcontroller.
These gearmotors might also be handy for building a robot arm.
Anybody know if the geared motors for the Rover 5, can be bought separately? With or without encoders? Where?
