Front or Rear wheel drive for more precise LEGO Mindstorms robot movement? Pro Preview

Should the robot be with a Front Wheel Drive or a Rear Wheel Drive to make it more precise? The answer is - front wheel will probably give you better results, but the wheel drive is not the most important thing. In this video tutorial on the LEGO Mindstorms Robots, we will do a few experiments to discuss the influence of the wheel drive on the precision of the movement.

A very popular construction on our platform is the Rear wheel drive construction from the FLL Robot Chassis section from the FIRST LEGO League course. So if you need an example for a construction with a Rear Wheel Drive, just check it out.

Move forward

Given our Box Robot when it moves forward it actually has a Front Wheel Drive. 

Move backwards

When our robot moves backwards it actually has a Rear Wheel Drive 

Front and Rear wheel drive or 4x4

It is possible to build a robot with front and rear wheel drive or to build a robot with 4x4, or two have a differential on the axles. But you have to decide whether it is worth it depending on the requirements for size and complexity that you have.
