STEP 6

Carefully place the small metal mounting

bracket onto the shaft of the servo, taking extra

care not to rotate the shaft from its set position

(Figure

2-5

). (During this step, it is important

also to make sure the four mounting holes of the

bracket are facing as straight up and down as

possible as shown.)

STEP 7

Screw in your remaining bolts through the

bottom plate of the assembly and into the four

standoffs, creating a completed robot-arm base

(Figure

2-6

).

STEP 8

The next step involves attaching four M3 x 10

mm standoffs (figure

2-7

). These will be much

shorter than the standoffs used to build the

robotic-arm base. ...
