According to a filing last week, the company raked in £826 million ($1.13 billion USD) in revenue in 2020 ... In "Learning Agile Robotic Locomotion Skills by Imitating Animals", we present a framework that takes a reference motion clip recorded from an animal (a dog, in this case) and uses RL to train a control policy that enables a robot to imitate the motion in the real world. By providing the system with different reference motions, we are able to train a quadruped robot to perform a diverse ...the Mujoco HAPTIX application [8]. We use the Modular Prosthetic Limb (MPL) as virtual prosthetic hand. The MPL is a highly dexterous prosthetic hand with 22 hinge joints and 13 motors. It also contains joint position and velocity sensors, motor position, velocity and force sensors, and IMUs in each fingertip [9].They improved on their previous dataset by providing RGB-D sensor data in addition to tracking data, increasing object diversity, adding controlled variation of the objects mass distribution, and creating benchmarks to evaluate models. ... MuJoCo, the Open Dynamics Engine (ODE), NVIDIA PhysX, and Havok (Erez et al., 2015). Those engines allow ...MuJoCo is a physics engine for detailed, efficient rigid body simulations with contacts. mujoco-py allows using MuJoCo from Python 3. This library has been updated to be compatible with MuJoCo version 2.1 released on 2021-10-18.
