Towards Aerial Physical Locomotion: the Contact-Fly-Contact Problem
نویسندگان
چکیده
In this paper we consider the problem of letting an aerial robot exploiting its contact with the environment in order to enhance its motion possibilities, in a way reminiscent of legged robots exploiting contact forces for locomotion purposes. As a representative and initial case study, we consider a quadrotor equipped with a 1-DOF arm able to hook at some pivot points, and needing to perform a maneuver from an initial hooked configuration to a final hooked configuration while passing though a free-flight phase between the two anchor points. To this end, we propose a dynamical modeling able to capture the various phases (hooked, free-flying) together with an optimization framework for generating optimal motion plans compatible with actuation constraints. Simulation results illustrate the effectiveness of the approach and the promising potential in terms of more advanced maneuvers.

متن کاملMulti-contact bipedal robotic locomotion
This paper presents a formal framework for achieving multi-contact bipedal robotic walking, and realizes this methodology experimentally on two robotic platforms: AMBER2 and ATRIAS. Inspired by the key feature encoded in human walking— multi-contact behavior—this approach begins with the analysis of human locomotion and uses it to motivate the construction of a hybrid system model representing ...
متن کاملLegless Locomotion: Concept and Analysis
This thesis presents a novel locomotion technique, called legless locomotion, for convex-bodied legged robots. The motivation for studying legless locomotion stems from the mobile robot recovery problem, stated simply as what should a robot do when trapped? Legless locomotion is the technique of locomotion for a legged robot which has no leg-ground contact, but can use the swinging legs to exci...

The aim of this study was to determine the parasitic and bacterial contaminations of houseflies found around various garbages, and to emphasize the necessity of fly control and taking more efficient strategies for garbage disposal. For this purpose, 800 houseflies from four garbage sources in the city of Kerman (hospital, urban, fruit & vegetable market, and slaughter house wastes) were collect...

In order to better understand the strategies of locomotion in small insects, we have studied continuous level locomotion of the wood ant species Formica polyctena. We determined the three-dimensional centre of mass kinematics during the gait cycle and recorded the ground reaction forces of single legs utilizing a self-developed test site. Our findings show that the animals used the same gait dy...
