How it works

This model has only one function, which is the purpose to what it has been designed (of course you can play with it but there is no steering). This function is the most important and takes the whole space in the model. It is basically composed of  :

    • A M-motor which drives the whole system (in red and yellow)
    • Articulated feet lever which deploy the feet under the bodywork (in blue)
    • A double linkage lever to maintain the chest of the transformer to be parallel to the feet lever (in pink)
    • A third linkage which connects the double linkage to the front, in order to reveal the head (in green)
    • The two arms attached to the chest which are moved by a last system of linkage (non represented here) :

This complex mechanism enable the transformation from a car to a robot :
