The system comes in a nice Tuff-Stuff toolbox that stores all the parts and tools. You get six servo-motors, two types of project bases, anodized aluminum struts, nylon connectors, a gripper hand, wiring, PC software, an assortment of tools, and an adapter box that connects the RCS-6 to your computer through the parallel (printer) port. The kit also comes with a video and a manual. Eleven projects are outlined in the basic kit -- everything from a slithering snakebot to a robotic arm to a golfer.
The robots are controlled through a console (Windows or DOS) program that's easy to operate, but sophisticated enough to allow macro programming for complex operations.
The interface not only has outputs for the six servos but places to add your own switches, sensors, lights, and other electronics.
The RCS-6 kit is a bit pricey for the hobbyist, but the quality of the components and the versatility of the system are outstanding and make it worth every penny. The RCS-6 system is rugged enough to withstand ultralight industrial use for demonstrations. According to the Robix Web site, several companies are using RCS-6 systems for demonstrations in labs.
