← TechnologyWhich outcome occurs when the Jacobian matrix is singular during inverse kinematics calculations for a robot arm?
A)Workspace singularities are bypassed
B)Joint velocity commands become unbounded✓
C)End-effector precision greatly improves
D)Computation load on CPU stabilises
💡 Explanation
Unbounded joint velocities result because the inverse of a singular Jacobian matrix yielding infinite values during IK calculations is the mathematical explanation; therefore small Cartesian movements equate to extremely large angular changes in robot joints, rather than stable movement or computation.
