“Ergo Jr is a low cost arm designed for education, easy to build and modify. Thanks to visual programming, it can be used in schools to realize from small to more complex projects. Originally designed in the “Mathematics: a beautiful elsewhere” artistic experiment, the Ergo Jr has been adapted to fit with education needs. It is a robotic arm, consisting of 6 motors allowing life-like movements and 3D printed elements. The use of rivets make the assembly, modification and reassembly easy. Ergo Jr comes with three tools for different interactions with its environment: a lampshade, a gripper and a pen holder. The robot is controlled with a Raspberry Pi board, and a camera helps it interact with the world. Everything in the robot is let transparent and accessible to promote an educative approach and an interactive technology. Poppy Ergo Jr is an open-source robotic arm based on modular 3D printed conception and low-cost XL-320 motors. Poppy Ergo Jr robot is a small and low cost 6-degree-of-freedom robot arm. It consists of very simple shapes which can be easily 3D printed with FDM printers. It works with Dynamixel XL-320 motors, and a Raspberry Pi for control.”
