-Build your robot and place the components on your breadboard as shown in the drawings. 
- 
-==STEP 1== 
-You can start working on the assembling of the robot holding the bottom of the bigger plexi base (refer to the “TOP” label engraved on the plexi to be sure you hold it in the right way). Attach the two small plexi bars with 2x Ø 3mm x 12 mm screws and respective nuts. Fix the motors with 6x Ø 2mm x 6 mm screws as shown in the picture.

-Fix the L298N motor controller module to the smaller plexi base using the 4x Ø 2mm x 10 mm screws (place the plastic spacers between it and the plexi base and fix it using the nuts as shown in the picture). To connect the breadboard, remove the protective film and attach the breadboard in the appropriate space.
