Meet SAM

The SAM (Science And Math) robot is able to move forward and back and pivot left or right--all with the high precision characteristic of stepper motors and all under the easy-to-program command of a graphing calculator. The basic robot serves as a platform, which can be expanded for a wide variety of additional activities. The many sensors available for the CBL, CBL2 or LabPro can be used to let SAM explore and respond to its environment. "Servo motors"--available at many hobby stores--can be added to activate arms or other devices. Students don't just learn about math and science--they learn to use math and science in activities that are fun, challenging and realistic. Click here to see the building instructions for SAM.

The SAM robot is only one of our Math Machines. A Pointer / Power Pulley is a great way to teach about angles, gear ratios, torque, rotational motion, and other topics.

The Basic Switch is perfect for controlling lights, buzzers, DC motors and more, plus it's a wonderful way to teach the basics of digital electronics and electric circuits.

The ideal choice for a starter project that does not require soldering is the Breadboard Controller.


"There are many examples of old, incorrect theories that stubbornly persisted, sustained only by the prestige of foolish but well-connected scientists. ... Many of these theories have been killed off only when some decisive experiment exposed their incorrectness. .. Thus the yeoman work in any science, and especially physics, is done by the experimentalist, who must keep the theoreticians honest."
