The robotic arm is a versatile robot that can pick up and move objects. It's designed to be expanded with new features over time, making it a good base for future robotics and automation projects.

Devlog 2 - Locking IN
This week I finished my robot arm (Yay) The design process took much longer than I expected because I had to go through a bunch of revisions. I kept running into issues, like incorrect dimensions or forgetting to add holes, which meant going back into Onshape, fixing the design, and printing the parts again. I used so much PLA on these but it was worth it
Once I was happy with the design, I printed all of the components, purchased the motors I needed, and assembled everything together. I’m happy to say that the arm works well overall, and seeing it finally come together after so many revisions was really cool.
The main issue I’m still working on is the power system. The battery I’m currently using isn’t very reliable and occasionally cuts out, which can cause the robot to stop unexpectedly. Aside from that, the project has been a success, and I’m excited to continue improving it in future updates plus I need to work on the IK but i am ready to ship
(BTW I did not timelapse IDK why)

I’ve made a lot of progress on the robot, but I also ran into several design challenges.
The first issue was the base size. My initial design had a diameter of 10 cm, which turned out to be too small, so I bumped it up to 14 cm and reprinted the part.
The second problem was the servo mount. It was designed with almost no clearance, making it too tight to fit the servo for me. (I asked my dad and he got it in but now I can’t get it out) I updated the design to provide the proper fit so I can put it in and take it out, which required another reprint.
The biggest issue was with the servo alignment. I had centered the housing instead of the servo output shaft, which caused the joint to move about 1 cm to the side and the top plate did not like that. After redesigning the mount around the output shaft, everything lined up properly.
With those issues fixed, I finished the top section of the base and started designing the first joint. Right now, I’m working on routing the wires cleanly through the robot while also figuring out the best way to mount the servo without sacrificing the overall look of the design.
