Closed-Loop Push Recovery for an Inexpensive Humanoid Robot.

Abstract:
Active balancing in autonomous humanoid robots is a challenging task due to the complexity of combining a walking gait with dynamic balancing, vision and high-level behaviors. Humans not only walk successfully over even and uneven terrain, but can recover from the interaction of external forces such as impacts with obstacles and active pushes. While push recovery has been demonstrated successfully in expensive robots, it is more challenging with robots that are inexpensive, with limited power in actuators and less accurate sensing. This work describes a closed-loop control method that uses an accelerometer and gyroscope to allow an inexpensive humanoid robot to actively balance while walking and recover from pushes. An experiment is performed to test three hand-tuned closed-loop control configurations; using only a the gyroscope, only the accelerometer, and a combination of both sensors to recover from pushes. Experimental results show that the combination of gyroscope and accelerometer outperforms the other methods with 100% recovery from a light push and 70% recovery from a strong push. |

Interaction and Learning in a Humanoid Robot Magic Performance.
In Siddharth Srivastava, editor,
Proceedings of the AAAI Spring Symposium on Integrating Representation, Readoning, Learning and Execution for Goal-Directed Autonomy,
Stanford, CA,
pages 578-581,
March 2018.
Abstract:
Magicians have been a source of entertainment for many centuries, with the ability to play on human bias, and perception to create an entertaining experience. There has been rapid growth in robotics throughout industrial applications; where primary challenges in- clude improving human-robot interaction, and robotic perception. Despite preliminary work in expressive AI, which aims to use AI for entertainment; there has not been direct application of fully embodied autonomous agents (vision, speech, learning, planning) to enter- tainment domains. This paper describes preliminary work towards the use of magic tricks as a method for developing fully-embodied autonomous agents. A card trick is developed requiring vision, communica- tion, interaction, and learning capabilities all of which are coordinated using our script representation. Our work is evaluated quantitatively through experimen- tation, and qualitatively through acquiring 2nd place at the 2016 IROS Humanoid Application Challenge.

Robot Magic: A Robust Interactive Humanoid Entertainment Robot.

Abstract:
In recent years, there have been a number of popular robotics competitions whose intent is to advance the state of research by comparing embodied entries against one another in real time. The IEEE Humanoid application challenge is intended to broaden these by allowing more open-ended entries, with a general theme within which entrants are ective application involving a humanoid robot. This year's theme was Robot Magic, and this paper describes our rst-place winning entry in the 2017 competition, running on a ROBOTIS OP2 humanoid robot. We describe the overall agent design and contributions to perception, learning, control, and representation, which together support a robust live robot magic performance. |
