← TechnologyWhich result occurs during robotic arm path-planning when kinematic singularity regions introduce excessive joint velocities?
A)Reduced positional control accuracy✓
B)Increased actuator torque requirements
C)Compromised trajectory smoothness
D)Elevated thermal energy dissipation
💡 Explanation
Reduced positional control accuracy happens because the inverse kinematic solution yields large joint movements for small end-effector changes near singularities. This amplifies quantization errors around these joint angles, limiting precision, therefore causing accuracy to decrease, rather than affecting torque or thermal properties that are more directly influenced by loading or speed.
