I got the EZ-Robot kit. Can the EZ-Robot board operate independently of the computer after programming it? Which motor driver should I buy for wheelchair motors? Are the servos from Vex Robotics Kit compatible with EZ-Robot? They either run too slow or don't run at all. What's the maximum voltage of the power supply that is plugged into the EZ-Robot board? I am hearing-impaired so please add captioning to tutorial videos. I also have Arduino Uno board that came with Ultimate Microcontroller Pack.
