Re: Crab Drive HELP!!***

GGCO,
Although crab drive is a great tool we don't use it all the time. It will only be incorporated into the robot design after careful consideration and playing the game. Don't make the decision at this point, play the game using chairs or tricycles or whatever and see if it is needed. If the team decides to use it then be advised that crab requires some strong mechanical attachments for both the top and botom, special handling to determine how assemblies are attached for steering, how to build a module so that both the wheel and the motor you use will fit into the space you require for turning the module and realize that crab by design puts the wheels closer to the center of the robot which compromises stability. After all of that is overcome, your drivers still need plenty of practice.
A so-so robot with lot's of practice will beat out a superior robot with no practice, every time.

As a personal request, can you include your first name in your profile? It makes it easier to respond. Thanks.
