Internet-Based Supervisory Teleoperation of a Virtual Humanoid Robot

This paper describes the approach used by the Sarbot-Team for controlling the Atlas humanoid robot during the DARPA Virtual Robotics Challenge that took place in June 2013. Herein we present a proposal for overcoming the restrictions on performance caused by limited bandwidth, high latency and the effects of signal degradation induced by beyond line of sight (BLOS) conditions, RF interference, and other related circumstances. Experimental evaluation confirmed the effectiveness of our approach and present an alternative for coping with constrained communication conditions during the control of humanoid robot deployed at unattended areas.

Integration of low-cost supervisory mobile robots in domestic wireless sensor networks

This paper presents a communication interface between supervisory low-cost mobile robots and domestic Wireless Sensor Network (WSN) based on the Zig Bee protocol from different manufacturers. The communication interface allows control and communication with other network devices using the same protocol. The robot can receive information from sensor devices (temperature, humidity, luminosity) and send commands to actuator devices (lights, shutters, thermostats) from different manufacturers. The architecture of the system, the interfaces and devices needed to establish the communication are described in the paper.
