This robot scans a probe in three dimensions to find the shape of an object. It transmits the contour data to a workstation for plotting.

This articulated vehicle uses rack-and-pinion steering to keep the trailer backing in a straight line.

This robot searches for dark objects to grab, lift and deposit elsewhere. The grabber and the arm are driven by one motor.

This plotter draws line-art on a sheet of paper. It also has a light sensor for scanning low resolution images.

This clock uses the RCX to keep accurate time on a conventional analog clock face. It has compact gearing and coaxial hour and minute hands.

This car has pneumatic active suspension that can raise each corner of the vehicle independently.

This VCR has a motorized top-loading deck, a working tape reel drive and IR remote control.

These digital calipers measure internal and external dimensions and depths up to forty studs, in half-stud increments.

This improved rotor design for the 8444 Air Enforcer twists the blades as they rotate, rather than tilting them.

This valve is based on Linc's design. It is a little more solid, and adds a touch sensor at the center of throw.
