PVC pipes were manually cut using a hand hexablade to prepare structural components.

All PVC leg segments arranged along with metal-geared servo motors for actuation.

Four handmade legs constructed using water pipes and 0.5W night bulbs as joint supports.

Battery connections being soldered to ensure reliable power supply.

Initial skeleton frame built using aluminum rods for lightweight structural strength.

Complete mechanical structure assembled and prepared for locomotion testing.

Final physical prototype reinforced using hard cardboard for added stability.

Concept blueprint showing a defence-oriented setup with a mounted gun and rear drone for surveillance.

Future visual concept showing the final colored design and expected appearance.

PVC pipes were selected to form a lightweight and durable mechanical hand structure.

Wiring and hardware components were installed to connect all mechanical parts efficiently.

Metal-geared servo motors were installed for precise and reliable finger movements.

Nylon threads efficiently transferred servo motion to each finger mechanism.

The fully assembled robotic hand was tested for alignment, strength, and responsiveness.

The working model successfully replicated real-time finger gestures and finger count.
