Abstract

This paper deals with Epi.q, a family of mobile robots whose main characteristic is a wheel-legged hybrid locomotion. These multi-purpose robots can be successfully exploited for security and surveillance tasks. The document presents state of the art security robotics, the Epi.q mechanical architecture, the concept behind the robot driving unit, three prototypes and the design of a new one.

Summary

Introduction

The increasing need for security systems for indoor and outdoor environments has stimulated the development of intelligent systems based on mobile sensors. Packbot [1], a tactile mobile robot developed by iRobot, performs dangerous tasks such as surveillance and reconnaissance, inspections or hazardous material detection It is a tracked robot with “flippers” that enable the robot to climb over obstacles, to self-right itself and to climb stairs, enhancing ability over a simple tracked robot. RHex [4, 5], developed by the Carnegie Mellon Robotics Institute, is a multi-purpose robot, which can be successfully implemented for security tasks It is characterized by compliant leg elements that provide dynamically adaptable legs and a mechanically selfstabilized gait. The authors worked for years on mobile robots, developing a family of mobile hybrid robots called Epi.q, due to the epicyclical gearing housed in the driving unit These multi-purpose robots can be successfully implemented for security and surveillance tasks.
