Wireless Controllers for a Robotics Class
Twenty-five handheld wireless controllers were soldered, assembled, debugged, and delivered for the students of a NEET sophomore robotics class to drive the robots they built.
I built 25 wireless controllers for the NEET Autonomous Machines sophomore project class, 2.S007 Design and Manufacturing I (of Robotic Systems). The design follows a tutorial by How to Mechatronics. Each controller carries an Arduino Pro Mini, two joysticks, two toggle switches, two potentiometers, six push buttons, an MPU6050 IMU, and an NRF24L01 radio, along with capacitors, jumpers, and a voltage regulator. Two rechargeable 3.7 V Li-ion batteries power it, and two laser-cut acrylic plates enclose it.
Starting from custom PCBs and a finished reference controller, I set up the workstation, soldered the IMUs, headers, and Arduinos, and worked around a board-version mismatch that needed extra wiring. I then laser-cut the covers, assembled all 25 controllers, and tested and debugged each one.
