SumoBot Robot Competition Kit (Serial with USB Adapter and Cable)

Build and program two high-quality SumoBot® Robots designed to wrestle in the mini-sumo competition ring (#27404), included in the kit)! The electronics consists of a surface-mounted BASIC Stamp® 2 module and an array of infrared sensors to detect your opponent and the edge of the Sumo Ring. Additional components include piezospeakers, resistors, pushbuttons and LEDs to build custom breadboard circuits for program mode selection and sensor state feedback. The hardware package includes black anodized aluminum chassis and scoops, servo motors, wheels, 4AA power packs (batteries not included) mounting standoffs, and screws for two complete SumoBot robots.

This kit comes with two printed texts. The SumoBot Manual has assembly instructions and test programs that take you from basic moves to one-on-one combat. Once you have your SumoBot robots up and running, give them a competitive edge and expand your skills by following the step-by-step activities in Applied Robotics with the SumoBot - an advanced text in our Stamps in Class series. Activities include friction analysis, self-calibrating sensors, memory optimization with multipurpose variables and a sensor flags register, and state-machine diagrams for sensor-based navigation. EEPROM data logging lets you record your robot's sensor and program states during a match, then display them afterward in the BASIC Stamp Editor's Debug Terminal - an excellent way to troubleshoot and analyze the performance of your program strategies.

Hold your wrestling matches on the durable 36 x 36 in. SumoBot Robot Competition Ring Poster, designed for use with the instructions and programs included in Applied Robotics with the SumoBot.
