Do
robots always need expensive, dedicated fixtures for workpart
positioning, or can they perform accurate assembly and manipulation
on "table-top" surfaces? Not only is table-top manipulation
possible, but the sliding that occurs can be used to advantage
if it is well understood.

Michael A. Peshkin offers readers methods of automating the
design of robotic manipulation strategies reliant on sliding
and friction. A central problem is that of predicting the motion
of a pushed sliding object, independently of the details of
the contact surface. This problem is solved: the locus of all
possible center of rotation is bounded. The results are used
to create automatically the complex sequenced of motions that
align workpieces by the use of sliding.
