← TechnologyWhich issue arises when kinematic redundancy surpasses actuator precision?
A)Internal force limit cycle oscillations✓
B)Unpredictable endpoint positional drift
C)Sudden kinematic singularities appear
D)Inconsistent encoder signal cross-talk
💡 Explanation
Internal force limit cycle oscillations emerge due to imprecisely controlled reaction forces. Kinematic redundancy allows multiple solutions, so minor actuator errors cause continuous adjustment in internal forces, creating oscillations, because the controller favors some motion, rather than accepting static balance.
