D. Manufacturing and Assembly

1. Early Prototype:

All linkages are designed using SolidWorks.

2. Assembly and Motion Testing:

Motion Testing:

4. Joint Design: Reuse the Link1b but cut the smaller end to 0.75cm (fit with 2 links and 1 ring of 0.25 cm thickness). The pin and the ring are connected using Gorilla glue.

5. Manufacturing Processes: 3D printing for all components.

6. Motor Control:  Use an Arduino and an L239D chip in the circuit to control the DC motor
