Which instability increases when a robot arm's controller relies excessively on matrix-based inverse kinematics for rapid, long-reach movements?

💡 Explanation

Actuator saturation and joint oscillations increase because the **Jacobian singularity avoidance algorithm** causes extreme joint speeds for desired end-effector positions; therefore, actuators reach their limits, creating oscillations, rather than stable, controlled motion, given physical robot arm constraints.
