Adding the motors for the arms
Locate the following elements for the arms:
- Two motors
- Four black 3L beams
- Six black connector pins
- Two gray connector perpendicular pins
The required pieces can be seen in the following image:
Figure 9.12 – Parts layout
Start this section by connecting the gray connector perpendicular pins to the gray part of the motors. It is easier if you have motors facing down, to ensure you properly build the part in the right direction to fit on the main frame. This is illustrated in the following image:

Next, add a black 3L beam to the other end of the gray connector perpendicular pins and insert a black connector pin in the middle hole of the black 3L beam, as illustrated in the following image:
