If we talk about Octocat, we are talking about one of the most representative figures of the community of developers and programmers since she is the official mascot of GitHuba mascot composed of two animals (cat and octopus) with anthropomorphic features and which came to life thanks to a project created, of course, thanks to the imagination of certain users.
Whether you are a programmer or developer or you usually like to download apps from Open sourceyou probably know Octocat, an octopus cat that accompanies all GitHub users and many wonder if it has 8 tentacles or 4 legs and a tail, a common two-dimensional dilemma that had to be solved when the first vinyl was launched. figures on the market.
At that time, the dilemma was resolved: neither 8 nor 4 tentacles with a tail, the land and sea creature Octocat has 5 tentacles. With this in mind, the guys at Infineon brought to life this well-known octopus cat, whatever you want to call it.
Bringing Octocat to life
To carry out the project of bringing Octocat to life, the guys from Infineon used a 3D printer and a set of pneumatic valves and the HAT Infineon Raspberry Pi.
Starting with the head, this was made using a fdm printer 3D using plastic paint for the face and eye area. To make the tentacles give a greater sense of realism, plastic, being a rigid material, was not a solution and silicone was used in its place.
To create the tentacle models, the same 3D printer was used, models which were then filled with black silicone and manually painted the suction cup area green with a spray can.
For the movement, a set of pneumatic valves connected Infineon valves, valves capable of moving according to the amount of air supplied inside each tentacle to offer a swinging movement that is as natural as possible while still being artificial. Obviously, to generate the air, an air compressor is needed, so doing this project wasn’t exactly cheap.
HAT control is managed by the chip TLE94112ES and is capable of handling different types of actuators such as the pneumatic valves used to complete this project. Includes libraries for C++ Yes Pythontherefore it offers very great versatility when carrying out any project and which we can access from here.
If you want to purchase this control HAT, you can do so directly from this manufacturer’s website for $34.37. If you want to know all the components that were used to complete this project as well as the code used and the 3D designs Octocat as well as the tentacles and molds used can be made through this link to the Hacker.io site, where we can find all kinds of projects.
