← TechnologyWhich motion error arises due to kinematic singularity?
A)Unpredictable axis trajectory deviation✓
B)Insufficient current control limitation
C)Excessive thermal expansion deformation
D)Encoder resolution rounding influence
💡 Explanation
Robotic singularity causes unpredictable trajectory deviation because the Jacobian matrix loses rank, leading to infinite joint velocities for a finite end-effector velocity, therefore motion becomes erratic, rather than simply thermal/current/resolution-limited effects.
