Lego Segway só com partes NXT 2.0

[Trigueiro]

This isn't the first Lego Segway (defined as a balancing bot on two wheels) -- that honor would probably go to Steve Hassenplug's Legway. However, the Legway used two EOPDs (Electro-Optical Proximity Detector) from HiTechnic Sensors to balance. What's cool about this project is that it needs only those parts found in a standard NXT 2.0 set. Most notably, it uses a light sensor in place of the expected (and non-standard) gyro sensor.

Espetaculo a forma como tem tanto equilibro  . Uma forma mais economica sem usar a lego :

This is a single chip balancing robot based off of a 555 timer and a servo modified for continuous roation. It uses 2 photo resistors for the sensor and has a simple proportional/derivative input.

E devem ler os comentarios que esplica o funcionamento.

So que não da para controlar e não tem sensores de COR mas o funcionamento é o mesmo .
