Which mechanism precisely controls end effector movements in robotic arm welding?

💡 Explanation

Precise end effector movement in a robotic arm relies on solving for joint angles using inverse kinematics computation based on position commands; therefor the arm moves correctly, rather than relying on individual direct joint controls without coordinate transformation.

• Which risk increases when a redundant 6-DOF robotic arm relies excessively on joint angle interpolation?
• Which outcome is LEAST likely by using feedforward control in high-speed hydraulic actuators?
• Which unintended consequence can appear when MOSFETs experience sustained, high electric fields?
• Which consequence results when excessive force during CNC lathe tool-path planning for an aluminum alloy?
