3D Printed Robot Arm
Summary
Robot arms are so facinating and versitale. I already have a 3D printer so it makes it so much more possible! I plan to try to implement computer vision later on, it’ll be a fun challenge for me in terms of software as well. There are so many possibilities with what I can do. I’ve had some experience working with hardware but not much, this will be a great opportunity for me to learn!
Plan
I’ll mainly be following this guide by How to Mechatronics, it’s very detailed and also provides room for me to adapt the project.
- Print everything, this will take over a week so I probably should complete that before the 10 days starts.
- Assembly! This should be quite straight foward if nothing goes wrong.
- Code it. I want to attempt to code it from scratch instead of using code the guide provided as a challenge, it’ll be fun tinkering!
- If I still have time, I want to attempt making it sort LEGOs.
