It came complete with all the parts to build the robot arm, the instructions are complete you do need to take your time and read them, we also got the USB interface kit and after playing with the joy stick for a couple of days we put the USB interface kit on and played another couple of days using the computer and programming the arm that way
He is a bit young for making it work transform back and forth from robot to car but he loves it in the car form, it should be a great toy to help with transitioning from gross to fine motor manipulation
It transforms into a nice looking robot and back to a car within seconds and is very slick looking, the only negative would probably be the box it came in, the product itself is awesome and fun
This is the most awesome remote control vehicle we have ever had !! It is a robot that stands up and balances and an incredible vehicle that rolls over most terrain
