Most industrial robot arms are holonomic (each joint’s position determines the end-effector’s position). However, underactuated robots (e.g., a free-floating space robot with fewer actuators than degrees of freedom) exhibit non-holonomic behavior. By moving joints in cycles, the base orientation can be changed without external thrusters.
The answer is stability and efficiency. Fixed wheels (like on a car) are mechanically simpler, stronger, and safer than swivel wheels. They don't slip as easily and they handle high speeds much better. non holonomic
In engineering, respecting non-holonomy is not a limitation—it is an opportunity to design elegant, underactuated systems that achieve complex goals with simple controls. The next time you struggle to parallel park, remember: you are not failing at driving; you are experiencing differential geometry in action. Most industrial robot arms are holonomic (each joint’s
This is the "hard" mode. In these systems, the robot or vehicle has more degrees of freedom in its position than it has in its controls. Essentially, The answer is stability and efficiency
