Vehicle Motion

Vehicles, motorcycles, and trailers with 1DOF, 3DOF, and 6DOF motion

Use the vehicle, motorcycle, and trailer body blocks to implement 1DOF, 3DOF, and 6DOF vehicle motion.

Motorcycle on inclined plane, 4-wheeled vehicle, 3-axle truck, and trailer. Each vehicle image has a coordinate system.
