Index

Shows the reader how to extend the capabilities of the Lego Mindstorms Robotic Invention system (RIS) by using Lego's own accessories and some simple home constructed units.

Build robots that can provide you with 'waiter service' when you clap your hands, perform tricks, 'see' and avoid objects by using 'bats radar', or accurately follow a line marked on the floor. The Lego Vision Command system is also covered, and this can enable your robots to literally 'see' the world around them and respond accordingly. Additional types of sensors including rotation, light, temperature, sound and ultrasonic. For the less experienced, RCX code programs accompany most of the featured robots. Also shown how to write programs using MS VisualBASIC running with the ActiveX control that is provided with the RIS kit.

Detailed building instructions are provided. The designs include rover vehicles, a virtual pet, a robot arm, an 'intelligent' sweet dispenser and a color conscious robot. (BP902)

Introducing Robotics with Lego Mindstorms

How to build a variety of increasingly sophisticated computer controlled robots using the Lego Mindstorms Robotic Invention system (RIS).
• Building techniques and mechanics needed to construct robots using the 'click-together' components supplied in the basic RIS kit.
• Explains to the reader, with little or no programming experience, how robot control programs may be simply constructed on their PC screens, using 'software' building bricks that are supplied with the RIS kit. Programs can then be 'zapped' over an infra red link to the robot's 'brain'. This brain, contains a programmable microcontroller that is also capable of acting on information from the robots various sensors.
• Write robot control programs using a conventional Windows programming language such as VisualBASIC in conjunction with the ActiveX control (called Spirit.OCX) that is also supplied with the RIS kit.
• Detailed building instructions are provided for all the robots featured. (BP901)
