The ROV3R is a Mindstorms augmented remote controlled Lego Technic Explorer

The concept of concurrentmeasurement of RPM and power of the engine in combination with an
electronically controlled automatic 4 speed gear box was presented previously: https://www.youtube.com/watch?v=4lfa-El7xR4

The benefit of an automaticcontrol of the 4 speed gear box is most evident for a 4WD off-road vehicle, where maximum torque is required in rough terrain, while higher speed is still desirable on smooth surfaces. The EV3 Brick of the ROV3R takes care of continuous assessment of the torque and optimizing it at a rate of 10 Hz. It will always operate at maximum torque and highest possible speed. All that is left for you is steering left and right as well as forward and backward. The Mindstorms augmented RC Explorer ensures highest power at maximum fun. The introduction of a Trial mode for very tough sections and active motor breaking for immediate stopping at maximum traction are just a few more features getting the most out of the EV3 Brick.

This version does not reqire the gyro sensor.
