Steep Slopes

We discuss the generation of maps of steep slopes covered with concrete frames and map information application for a quadruped walking robot, TITAN XI. Suspended by a pair of tethers, the robot requires map information of the environment, localization for walking and tether control for weight compensation. After introducing TITAN XI, we propose map generation using Topcon’s Total Station range-finder, robot self localization, and weight compensation by tether control based on map information using one Total Station. We conclude with a review of the results of walking experiments on an undulated slope using TITAN XI.

Steep Slopes

We detail a step over gait for a quadruped walking robot that maintains a continuous walking with sufficient stability margin for avoiding ferroconcrete reinforcement frames covering steep slopes. For this gait, the robot must adapt itself to terrain and step over these frames. We propose a terrain-adaptive gait based on an intermittent crawl gait using map information. After introducing the gait control algorithm, we show results of graphical simulation to verify the proposed algorithm. Then, these discussions are established by walking experiments using the developed quadruped walking robot named TITAN XI.

Steep Slopes

Construction work on steep slopes is difficult and dangerous, but it is also difficult to automate work at such type sites. One reason is that construction sometimes calls for movement across a ""Free Frame"" - a structure built to keep a slope from collapsing - and because of the ups and downs of the natural slope, it is difficult to design a purposeful simple mechanism to move on this frame. We propose a sensor-based quadruped walking robot that moves on the slope without damage to the surface of the frame, and developed a TITAN VII prototype robot. We detail the techniques required by this type robot to move and work on steep slopes. Practical ways of A) detecting positions and orientations of frame surfaces on rough slopes and B) stepping over the frame and maintaining the stability of the robot using positioning, are presented and their effectiveness is verified through experiments.
