The influence of gravity on trajectory planning for climbing robots with non-rigid legs
In this paper questions related to the occurrence of departures of a legged climbing robot from the given trajectory are considered. The basic idea of the paper is to show that, if there are slackness and non-rigidities, the legged climbing robot moving upon an inclined or vertical plane, departs systematically from the planned trajectory. It is demonstrated that these departures result from the gravity and are of systematic character. It is also shown how the inclusion of torsion effect changes substantially the nature of systematic errors arising from robot's movement along the inclined surface.
