← TechnologyWhich control system failure arises when a robotic arm's tactile sensor incorrectly estimates external force during a pick-and-place operation?
A)Force feedback oscillation begins loop✓
B)Singularity avoidance matrices collapse
C)Process heating increases exponentially always
D)Kinematic chain Jacobian matrix freezes
💡 Explanation
Force feedback oscillation begins because inaccurate force data creates an inappropriate torque command, triggering continuous over-correction via proportional-integral-derivative (PID) control. Therefore, arm stability degrades, rather than kinematic lock occurring or unintended process heating.
