Finding Parts and Programming Environments
You can order sensors, motors, and other robot parts from several sources. Although you can probably find the Robotics Invention System (RIS) at a local toy store, you'll hardly ever see extra
motors and sensors.
LEGO Sources
Table A-1 lists three places where you can get RIS accessories.
Table A-1. Sources for LEGO Parts

Pitsco LEGO DACTA sells LEGO's educational products, including RIS, a programming environment called ROBOLAB, classroom packages, and a fine assortment of spare parts.
Parts
Table A-2 lists the parts you may wish to buy along with their prices at the three sources shown in Table A-1. This information is current as of mid-1999. (LWS is LEGO World Shop, S@H is
LEGO Shop-at-Home Service, and Pitsco is Pitsco LEGO DACTA.) Note that the Shop-at-Home Service does not charge extra for shipping, so the list is not exactly comparing apples to apples.
