Hi,
Im relatively new to maya and im having a problem with a rig. Ive modelled a claw machine and rigged it so that when I rotate the swivel at the base of the machine, the whole claw rotates with it. It works fine up until I try and animate the machine moving- then it doesn't rotate anymore. I don't know whether theres a problem with my rig or if its something else.
Any help is appreciated.

thanks
