Developing a reliable humanoid robot that operates in uncharted real-world environments is a huge challenge for both hardware and software. Commensurate with the technology hurdles, the amount of time and money required can also be prohibitive barriers. This paper describes Team THOR's approach to overcoming such barriers for the 2013 DARPA Robotics Challenge (DRC) Trials. We focused on forming modular...
The challenging task of navigating in cluttered environments has been studied extensively with indoor autonomous mobile robots. However, few approaches attempt to estimate real-valued costs for manipulating said obstacles with no prior knowledge of the environment. Our approach not only estimates these costs but also models the uncertainty inherent in making such estimates. We present an algorithm...
Imitating the motion of a human operator is an intuitive and efficient way to make humanoid robots perform complex, human-like behaviors. With the help of recently introduced affordable and real-time depth sensors, the real time imitation of human behavior has become more feasible. However, due to their small footprint and high center of mass, humanoid robots are not inherently stable. The momentum...
Bipedal walking in human environments is made difficult by the unevenness of the terrain and by external disturbances. Most approaches to bipedal walking in such environments either rely upon a precise model of the surface or special hardware designed for uneven terrain. In this paper, we present an alternative approach to stabilize the walking of an inexpensive, commercially-available, position-controlled...
Dynamic bipedal walking is susceptible to external disturbances and surface irregularities, requiring robust feedback control to remain stable. In this work, we present a practical hierarchical push recovery strategy that can be readily implemented on a wide range of humanoid robots. Our method consists of low level controllers that perform simple, biomechanically motivated push recovery actions and...
