6DOF Robotic Arm

thingiverse

This robotic manipulator is a 6DOF marvel. It took some elbow grease to use minimal hardware, but it was worth it. You'll need 7 HiTec HS-422 servos to get started. The design and build process was intense, but the results are well worth the effort. This model is on the advanced side, but with great rewards waiting for those who complete it. The arm itself stands at approximately 35cm (16" inches) tall. To make sure the gripper slid smoothly, I had to perform some light sanding. Additionally, I tweaked the roll and tilt servo mounts so they would work seamlessly without nuts or bolts, opting for self-tapping screws instead. It's definitely more straightforward than wrestling with tiny hardware to mount servos. Take it from me - this method is far less hassle! If you're interested in contributing to this project's evolution, feel free to share any comments that might improve it. I've uploaded all the necessary parts online for anyone looking to replicate this build. The printer settings used were as follows: MakerBot Replicator 2 with a resolution of 0.2mm and an infill percentage of 10%. I also included notes on print settings - standard ones worked like a charm. Be sure to apply new tape to your build plate before starting the project.
