Control of redundant robots at singularities in degenerate directions

An algorithm for controlling redundant robots at singularities, when the desired motion is in a degenerate direction, is proposed. This case is not supported by other solutions, using only Jacobian information, proposed in the literature. Our algorithm uses Jacobian and Hessian matrices and it allows to choose the configuration of the robot when it exits the singularity. The algorithm was tested on a 7 degree of freedom robot.
