The Raspberry Pi Robotics Masters Robo HAT MM1 is an open source robotics controller designed to remove the the initial barriers to starting any robotics project by providing all the hardware you need in one simple, easy-to-use form factor. watch the demonstration video below to learn more about the Robo HAT MM1 created by Robotics Masters specifically for the Raspberry Pi mini PC. Although the Raspberry Pi robotics board is also compatible with Jetson Nano and can even be used standalone.
The Robo HAT MM1 removes the need for a PWM driver, external power, or voltage regulators, and adds additional functionality. Wide compatibility with many open source software libraries such as CircuitPython, SeeSaw, and Arduino IDE means that you can use Robo HAT MM1 in the way that works best for your specific project. The hardware schematics and software will be fully available and open source.
Launched via the Crowd Supply website this week the robotics board is now available from just $45 with free shipping throughout the United States and worldwide shipping available from just $10. Its creators explain more about the inspiration behind the Raspberry Pi robotics board.
“One of the core drivers of this project was the changing curriculum in Australian schools – all students must now learn to code as part of their technology course (this change came through in January 2019). Project Based Learning (PBL) – learning through doing or creating something seems to be the best way to teach students programming. We wanted to create a platform that could be used to learn the very basics of programming, all the way up to robotics and autonomous cars and beyond! The Robo HAT MM1 is one of the ways we hope to achieve better programming education in schools.”
