Robotic arms require precise spatial control to perform tasks like manufacturing, welding, or surgery. Engineers map the robot's joints using vector spaces. The gradient of a velocity potential field is calculated in real-time to plan smooth, collision-free paths, enabling autonomous robots to navigate complex environments efficiently.
