Robot 2 – Mecanum Wheel Chassis

•  The mecanum wheels allow for movement in any direction without changing the orientation of 

the robot (forward, backward, strafe left and right) making the robot more maneuverable. This 
makes it easier to line the robot up on a target, goal, or ordinance. The mecanum wheels work 
best on smooth flat surfaces.

•  Like Robot 1, the chassis orientation can be flipped either way (the vertical rails just need to be 

attached to the other side). With the motors underneath the chassis, the robot has higher ground 
clearance to drive over obstacles. With the chassis flipped so the motors are on top of the chassis, 
the chassis is lowered bringing mechanisms closer to the ground.

•  The mecanum wheels can be swapped out for standard wheels that provide better traction or for 

driving over uneven terrain.

•  The longer wheelbase gives more balance and helps avoid tipping.
