Low-Cost Robotic Arm Project
Build, learn, and master engineering fundamentals through hands-on robotics
Project Overview
Our robotic arm project is designed to be your gateway into the world of engineering. This isn't just about building a robot—it's about understanding the fundamental principles that power modern technology.
Through this project, you'll learn mechanical engineering by designing joints and linkages, electronics by wiring sensors and actuators, programming by coding movement algorithms, and mathematics by calculating kinematics and control systems.
What Your Robot Will Do:
- Look around using computer vision
- Pick up and move objects
- Follow programmed paths
- Make basic decisions
- Connect to other devices
