I am making a bot that when finished will be able to move (With wheels), will have two robotic arms and a spinning head. It runs off of a car battery and weighs around 130 lbs. I have the frame and most of the motors mounted. Ive programmed it to move with a Bluetooth module and android app. The problem is that the app does not have enough buttons to control all of the features. I would appreciate it if anyone could recommend rc remote that has enough functions to control it and an rc reciver that I should use.
Have a look at model aircraft transmitters - eg Futaba
You might consider using a wireless router as the radio portion of your project on the robot.
How many is "enough"?
