Quick Information

  • Model Number : RQP-D01



This robot, equipped with 4 legs of each 2 degree of freedom and 8 servo motors, moves forwards, backwards and changes its moving direction freely as well like four-legged animals do. By experiencing this product, users can understand and learn about the moving or walking algorithm. Besides, by using extension module such as proper sensors, etc., you can diversify its movement. That is, if you adopt some sensor module in it, then, the robot moves forward avoiding collision against front obstacles or tracing after some specific objects. Users also can make their own program or modify supplied program with ease.
