How can I control this without using methods such as arduino? I am thinking of replacing the motors with these http://hobbyking.com/hobbyking/store/__24926__B20_30 _24S_Brushless_Inrunner_Motor_3860kv.html
so what speed controller and other accessories do I need? I plan on using my spektrum aircraft radio.
Thanks in advance!
The chassis is smaller than I thought would be, leaving very little space inside it for electronics such as motor drivers and Arduino. I hook up my receiver to Arduino to control the robot from a transmitter, it works fairly great but there are some issues about the motors.
One of the motors I received has a bit of issues, the gear doesn't seem to engage, so I have to buy one myself. The motors are quite weak - I tried supplying 12V to them and they still don't have sufficient torque. The wheels are too soft that it can't grip well to the floor, and thus the robot may have some difficulty moving it a straight line, and turning usually results in a lot of slipping between the floor and the wheels.
