Anybody who’s been to GitHub earlier than has little question come throughout the unforgettable Octocat mascot. Its pointy ears and pleasant smile accompany a large library of code shared by hundreds of individuals over time. At present we have got an lovely Raspberry Pi venture to share created by the Infineon Group who’s utilizing a Pi to deliver the GitHub Octocat mascot to life.
More often than not once we describe a venture as “bringing one thing to life,” we’re referring to a form of robotics. At present is not any exception, however there is a pleasant twist that makes the creation notably fascinating. The group is utilizing pneumatics to make silicone tentacles flap on command. The Pi is ready to handle every tentacle utilizing Infineon’s new DC Motor Management HAT.
The top for Octocat was 3D printed utilizing an FDM printer and completed by hand with paint. The tentacles, nonetheless, are one other story. To create these, the group designed and printed a few molds and used silicone to kind them. Every tentacle is managed utilizing pneumatic valves linked to the Infineon DC Motor Management HAT.

The valves are in a position to trigger motion by filling small channels inside every tentacle with air. This causes them to wiggle and flop in a extra pure trend, or a minimum of as pure as pneumatic valves with silicone tentacles will be. Based on Infineon, the DC Motor Management HAT sports activities a TLE94112ES chip that gives 12 half-bridge drivers and is ready to function a wide range of actuators which incorporates the pneumatic valves carried out in Octocat’s wiggly tentacle system.
The HAT consists of libraries in each Python and C++. This gives a little bit of flexibility with regards to creating Raspberry Pi tasks of your individual. All the code used on this venture is totally open supply and accessible for anybody to make use of and modify as desired.
If you wish to get a better take a look at this Raspberry Pi project and see it flop for your self, head over to the official venture web page shared to Hackster. You may as well discover the DC Motor HAT over at Infineon’s website.
