You need to choose one of the valid kinematics types. As far as I know there is no documentation on them, and you have to guess. > Not sure what you mean by verifying forward and inverse matching for all > inputs? A kinematics routine defines a translation from joint positions to cartesian location, and the inverse transformation. Both pieces of code have to match, so that if you pass the same numbers through one way, then back through the other, you should get exactly the same numbers back. This can mean having to find alternative formulations of the equations if floating point arithmetic gives subtly different answers, as that will lead to the joints drifting. This isn't a problem with Gantrykins, there is no maths in there. -- atp The idea that there is no such thing as objective truth is, quite simply, wrong. ------------------------------------------------------------------------------ Cloud Services Checklist: Pricing and Packaging Optimization This white paper is intended to serve as a reference, checklist and point of discussion for anyone considering optimizing the pricing and packaging model of a cloud services business.
