3D design of the white parts in SolidWorks, 3D printed on a 3DS Projet 3500HD Max. Pieces sized to match LEGO Technic geometry
Motor, chassisbeams, gears, differential and wheels: LEGO Technic.
Electro: 4 channel relay card. The usage of the relay card makes dynamic breaking possible. If fitted with the proper hardware, speedcontrole of the cars back- and forward movement, also can be achieved.
