RoboBoard
Imagine a fully functional robot that's only assembly step is soldering together the board. Our ability to produce cheap printed circuit boards (PCBs) has been optimized over the past decades, and utilizing this process in robotic design could potentially make fully functional robots much cheaper to produce. The idea behind this project is that electronics, not mechanisms, are the most fundamental and difficult to produce component of small robotics, and that cheaper robots can be produced with mechanisms being produced by the optimized PCB production process. This robot uses an STM32 microcontroller, and has a suite of sensors, including three IR sensors, two bump sensors, and an IMU.
This concept of building a fully functional robot from minimal manufacturing processes is expanded in NanoBot, which is a more developed robot using an ArduinoNano as the computing core for the PCB robotic base.
