Bipedal Robot Remains Upright Even When Whacked by Shoe on a Stick

Posted on March 16, 2012

Researchers at The Robotics & Mechanisms Laboratory (RoMeLa) at Virginia Tech have created a bipedal robot that is able to stay upright despite being repeatedly hit with a shoe on a stick. The researchers say the robot, CHARLI-2, uses 3 sources of sensory feedback to remain stable. They include filtered IMU angles, gyro rate readings and proprioception information based on joint encoders. The robot uses this data to apply stabilizing torques at its ankle joints. The first video shows CHARLI-2's stability test and the second video (from last year) shows the robot walking around. Take a look:
