I think the fact that the sqrt term can be negative indicates a problem somewhere. It might be as simple as the fact that the maximum reach of the robot is a sphere, but that axis limits are a cuboid, or it could be something more fundamental. I am not at all clear what p-sub-w-sub-x etc mean, they don't appear in the earlier equations, but I never really did get the hang of matrix algebra. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ Try before you buy = See our experts in action!
