Which outcome occurs when a robotic arm's joint controller accumulates substantial steady-state error?

💡 Explanation

A steady-state error causes persistent positional inaccuracy; because the controller attempts to compensate with maximal effort, this leads toward a kinematic singularity rather than efficient motion; therefore, a singularity is approached, rather than improved efficiency under steady control.
