The base
The base, which comes in the original version with two reduction boxes and 9 V engines has a free front wheel. The motors can be controlled independently allowing their use in several types of projects.
Projects can be from the simplest, like our combat robot in which we do not have electronic circuits, intermediaries like the robot control brush being adapted, and to the more advanced, projects using microcontrollers like the Arduino or others.
