Robotic Arm
A user-controlled table-top robotic arm
The Challenge
Design and build a working robotic arm that can be controlled by the user.
The Solution
The purpose of the project was to build a successful, working robotic arm, while learning necessary engineering skills such as CAD, 3D printing, soldering, and troubleshooting. The robotic arm is built completely of either PLA or resin 3D-printed parts. The robotic arm has four servos and four potentiometers, with an Arduino translating the resistance of the potentiometers into servo movement. This allows the robotic arm to be controlled by a user. All the electrical components are soldered and connected to a PCB housed in the base of the robotic arm. The final product was a working robotic arm with great range of motion that is capable of picking up small objects. Below is a link to the PDF report that goes into further detail.
