Summary

This article lists five DIY robot projects, including an arm, a rover, a self-balancing robot, an ACT policy-trained robot, and a line follower, with details on parts, calibration, and tuning techniques.

here are 5 robots you could build after reading this article: 1. the SO-101 arm, $122 in parts build it, calibrate every servo, teleoperate it, then print your own gripper fingers 2. a ROS 2 rover that maps a room and navigates it SLAM Toolbox and Nav2, and you can do the whole thing in simulation with no hardware at all 3. self-balancing robot it will not stand up until your filter and your loop timing are both correct, which is exactly the point 4. an ACT policy trained on your own demonstrations record 50 demos, train, deploy, measure the success rate, then record 50 more and beat it 5. line follower with PID your first closed loop, and filming it badly tuned next to properly tuned is the whole interview answer that's what will make you at least advanced junior at Robotics Engineering and will help you to get your first offer in robotics company

here are 5 robots you could build after reading this article:

  1. the SO-101 arm, $122 in parts build it, calibrate every servo, teleoperate it, then print your own gripper fingers

  2. a ROS 2 rover that maps a room and navigates it SLAM Toolbox and Nav2, and you can do the whole thing in simulation with no hardware at all

  3. self-balancing robot it will not stand up until your filter and your loop timing are both correct, which is exactly the point

  4. an ACT policy trained on your own demonstrations record 50 demos, train, deploy, measure the success rate, then record 50 more and beat it

  5. line follower with PID your first closed loop, and filming it badly tuned next to properly tuned is the whole interview answer

that’s what will make you at least advanced junior at Robotics Engineering and will help you to get your first offer in robotics company

A detailed description of building a low-cost (<€5,000) robotics research setup including an industrial-grade arm, cameras, and teleoperation software, designed to fit next to a desk. The author argues that recent advances in affordable hardware and foundation models now allow individuals to conduct meaningful robotics research independently.
