ARDUINO ROBOTIC ARM 4 DOF
Contents
Introduction
The MeArm project aims to bring a simple Robot Arm well within the reach and budget of the average educator, student, parent or child. The design brief that has been set out with was to build a full robot arm kit with standard low cost screws, low cost servomotors and using less than 300 x 200mm (~A4) of acrylic. While trying to solve the robotic problem, user also can get to learn about science, technology, engineering, arts and mathematics or STEAM.
The more people who are involved with these STEAM activities the more chance they have of solving all of life’s problems. The MeArm is an Open Sourced Robot Arm. It’s small, like pocket sized and that’s for a reason. It can be cut entirely from an A4 (or more accurately 300x200mm) sheet of acrylic and built with 4pcs cheap hobby servos. It supposed to be an educational aid, or more accurately a toy. It still needs some tinkering but is at a good first draft state.
