This question is mostly asked by people who have not seen a RCV up close to understand the fundamentals behind the controls that maneuver the vehicle via remote signal. Of course it might require deep technical exploration to go into the real in-depth analysis of these gadgets, but a relatively simpler explanation given below would help an average user to understand the broad concepts good enough to give an appreciation of the underlying principles in the entire process.

Each remote signal is synchronized to a receiver built within each RCV. The receiver sends the signal to the censors located at the steering which commands the motor to turn the wheels either right or left. This is done in a fraction of a second to maintain reaction time while driving at high speed. These censors are prevalent on parts of the vehicle that require constant change. Throttles on many vehicles are fixed and the engine remains at the same speed all the time but some models have incorporated a sensor which controls even the throttle.

For RCVs that fly or undertake under water explorations there are many more censors that receive signals to control the vehicles instruments and tools while under operation. Technology has made it possible to install computers on board these vehicles to increase the signals, thus adding operations that can be conducted on each vehicle.
