imajor Posted January 2, 2012 Posted January 2, 2012 Hi all, This is an experiment I wanted to do for a long time. Nothing special on the receiver side, a single motor does the steering, no return to center. On the remote control side, there is an NXT brick, and two motors. One of them are used as an input for the brick, that is the wheel I can operate. The NXT brick detects rotation done to the steering wheel, and turns on/off the steering motor in the vehicle using the other motor. The more I rotate the wheel, the longer the steering motor is turned on. I also improved the program to take into account the backlash of the vehicle, so if you turn right, then left, it keeps the motor on for a longer time period, to get rid of the backlash. Since this is only affecting the remote controller, I thought that maybe Lego will build in something similar to the remote controller of the upcoming rock-crawler. Unfortunately I couldn't test it in action yet, because the steering I made for the 8110 is not good enough, if I let the wheels touch the floor, the M motor is not able to steer the wheels properly.
