Robotic Arm

This is a Simple Robotic arm created by me. It just uses 3 Servo Motors 1 one for gripper and 2 for the arm. This is just a Basic arm for now because I could not make good jaws right now and will improvise the robotic after on.

Why

I created this project because it is cool and i wanted to make it one (Because I saw it in Iron man movies). I Built this Project to get to know about how structure and detailing in Fusion 360 can effect the full Project. I want to integrate in it later (just liek Iron man again) and amke it even cooler.

Questions

How big is the Robotic arm PCB?

It measures 106.7 × 58.4 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Robotic arm use?

8 parts, built around the EG1218. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Robotic arm KiCad files?

From the ryukgod26/robotic-arm repository on GitHub, at the commit this page was made from: the board is Hardware/robotic_arm/robotic_arm.kicad_pcb and its schematic Hardware/robotic_arm/robotic_arm.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Robotic arm design in my own project?

Its repository states no licence, so its author keeps all rights: ask ryukgod26 before reusing the design.
