My contribution

For this week’s machine design assignment, I was in charge of design of basement part. As the group, we decided to make robot arm which consisted of a hand part and a basement part.

Rotational Base

The base part of the robot arm was created as follows.

Gear data was created using Fusion.
Timing belt is 2mm pitch.
Therefore, the mountain of gear was also 2 mm pitch.
Gears were stacked into pillars using acrylic of 5 mm thickness.

The above data was processed by laser and used as a base of robot arm.
It became as follows in combination.
