Which outcome occurs when a robotic arm's joint encoder fails during execution of a pre-programmed motion involving inverse kinematics?

💡 Explanation

A joint encoder failure compromises position feedback loop signals, thereby triggering kinematic miscalculation in trajectory control because accurate derivation of joint angles become mathematically impossible using forward kinematics alone; therefore, the end-effector reaches an incorrect position rather than following its intended path, despite the motor still running rather than immediately stopping.
