The VEX Motion Subsystem contains a variety of components designed to help make robots
mobile. This includes a variety of wheel sizes, tank treads, and other options. Robots using
these in different congurations will have greatly varying performance characteristics.
Tank Tread components and wheels can also be used to construct intake mechanisms and
conveyor belts. These are frequently used on competition robots.
Introduction to the Motion Subsystem, continued
When designing the Motion Subsystem of a robot it is important to think about several
factors:
• First, it needs to be able to perform all the moving functions of the robot.
• Second, it needs to be robust enough to survive normal robot operation; it also needs to be
robust enough to survive some abnormal shock loads.
• Third, it needs to be well integrated into the overall robot system.
The Motion Subsystem combines with the Structure Subsystem to form the primary physical
parts of the robot. The motion components will be used throughout a robot’s construction,
and will likely be part of every major robot function. As such, this Subsystem needs to be well
thought out in advance.
