Project Description

This project aims at developing efficient algorithms for solving the following strongly NP-hard problem: given an arbitrary collection of kinematic constraints among a set of solids, generate all spatial configurations of these solids that satisfy them all. When the number of feasible solutions is infinite the algorithm must also be able to find a discretization of the whole solution space.

In this project, the solids are the rigid links of a robot mechanism, and the kinematic constraints are either those induced by the kinematic loops of the robot (its closed sequences of solids and joints) or those induced by contact constraints with the environment.

Finding an efficient and general method to this end, without limitations on the type and amount of considered constraints, is still an open problem of Robotics whose solution has been pursued along the last decades because it finds important applications to high level robot programming, to forward and inverse kinematics, to trajectory planning of closed kinematic chains, to singularity detection, to workspace computations, and to the control of redundant manipulators. However, an efficient solution seems now possible by using a technique for solving multilinear equations that is being developed by the group of this proposal.

The developed algorithms would be integrated into a general-purpose software package for specifying, planning and simulating collision-free trajectories for arbitrary-architecture robotic systems.
