Engineer Martin Stoelen has released some videos showing the operation of a 3D printed robotic arm called GummiArm! This isn’t just any robot arm, it uses AX-18A Dynamixel Actuators to turn spools with elastic bands, acting as pliant linear actuators. This gives the GummiArm a unique, springy response to its environment! The mounts are available on Martin’s GitHub. This project is assosicated with the DeCoRo project at Plymouth University.
