These are designed for children to learn about STEM and robotics with Lego, in the disguise of secret agent games.
The robots you can build are fairly interesting and colourful, going under such names as TechnoJaw, GigaMesh, SnapTrax and ShadowStrike. Each set comes with a different coloured remote and P-Brick pair.
The remote operates in three modes. One is secure mode - which simply sets the channel the remote operates in, and broadcasts this to the P-Bricks - the first two of these channels also corresponds to Lego Manas channels. There is a control mode, which allows buttons 12 and 45 to control the movement of a P-Brick, or a Lego Manas. In this mode . There is also a game mode, where the control codes sent are used to play one of the CD-Rom challenges.
The P-Brick is programmed from the PC via a VLL socket in the back - using two half pins to connect it, and a triangle polarity lock. When disconnected- the light can be used for decorative purposes - and often is in the modes on the brick, and the other sensor used as a light sensor.
The P-Brick has two fixed motor outputs, a VLL output, an array of LED outputs, and a two IR outputs. It has a touch sensor input, two IR detectors, and a VLL input. The SpyBotics set can be programmed from MindScript and NQC. It is also capable of controlling Lego Manas and communicating with the Lego RCX as well as other SpyBotics bricks.
