Roboticists have to come up with all sorts of creative ways to stress test their robots. iRobot went straight to a baseball bat to demonstrate the resilience of a prototype robotic hand it’s been experimenting with. Unlike most robotic body parts, which are made of rigid materials, this hand is made of flexible and soft rubber-like polymers. This means that instead of requiring extraordinarily precise, calculated movements to manipulate object, the robot’s fingers can press against things until they bend and grip. The individual fingers house electronics like tactile sensors and fishing line connected to motors that control movement. VIdeo is worth watching for how impressive a seemingly simple design and control architecture can be. Click on the image or the title to learn more.
