Is there any way that we can control our robot without a driver station/ dashboard? Kinda like an RC car only with - say a 360 controller?
There has to be some application formatting and sending the control packets to the robot. At the moment, very few solutions exist that are capable of doing that. For your specific example, a 360 controller, assuming it has USB, can be connected and used on the supplied driver station software.
