Which outcome occurs when a robotic arm's resolved-motion rate control relies predominantly on numerical approximations of the inverse Jacobian matrix?

A)Precise trajectory tracking is maintained
B)Singularity avoidance becomes guaranteed
C)Accumulated position error increases
D)Computational load is uniformly reduced

💡 Explanation

Accumulated position error increases because numerical inverse Jacobian calculations introduce approximations, causing imprecision during transforms; this imprecision aggregates with each iteration and accumulates into considerable position error. Therefore, error accumulates, rather than guaranteeing singularity avoidance under ideal conditions where analytic values are used.
