Introduction
The full device assembly is shown below. Highlighted are the electronics housing (red), rotation linkage (blue), vertical parallelogram linkage (yellow), and claw linkage (orange).
Mechanism Design
...
Most of the joints in the assembly consist of a single bearing, 1/4" machine screw, and 1/4" locknut, with washers if necessary. This joint design
allows the bolt (the joint pin) to freely rotate while still preventing the pin from falling out. The bearing reduces friction even further, but it
is not strictly necessary - the hole in the second link could simply be made smaller.[EXPLODED JOINT VIEW]
We have made all the SolidWorks files for our project available for download.
