Task 1
I designed a gripper, assembled the parts in Fusion 360, and simulated its operation.
Steps
1.Design: Created parts like the base, arms, linkages, and mounts.
2.Assembly: Assembled the parts using joints (rigid, revolute, and slider) in Fusion 360.
3.Simulation: Tested the gripper’s movement and strength.

Electronics
A voltage multiplier circuit using a 555 Timer IC and capacitor charge pumps steps up 9V to 18V and then cascades to achieve 27V. The 555 Timer is configured in astable mode to generate a square wave, driving the charge pump stages. Each stage uses capacitors and diodes in a voltage-doubling configuration to incrementally increase the voltage. Low-drop diodes and appropriately rated capacitors ensure efficiency and reliability. This compact design is ideal for low-input to high-output DC voltage applications and can be simulated in TinkerCad for verification.
