Developers from IHMC Robotics demonstrated a high-speed robot moving on two limbs and capable of speeds up to 16 km per hour with a relatively small size. The solution to the main problem of robots on two supports – maintaining stability, is achieved without the use of complex mechanisms, sensors and sensors. Stability is achieved due to the high speed of movement of the robot, similar in appearance to an ostrich. The movement of the robot is carried out by transmitting torque from the electric motor through an elliptical drive to the legs of the device. At the same time, a high speed is achieved, which, at a scale comparable to humans, could be about 50 km per hour. The disadvantage of this mechanism is the lack of stability at rest. When braking abruptly, the robot capsizes. Despite skeptical remarks that appeared on the network about the low suitability for using such a prototype in practice, this model has an elementary kinematic scheme and low energy consumption. This development will be another step towards creating an effective mechanism, based on two pillars and simulating the movement of a person.
