[TrackWalker-II] : Volcano exploration robot, TrackWalker-II

We developed a new locomotion mechanism, called TrackWalker in 2010. It consisted of three track modules. It mounts six actuators: three motors for standard tracked locomotion, two motors for sub-tracks' motion to change mounting angles, and one motor for simple legged motion. We conducted outdoor experiments in Mt.Asama in 2010, and we found some problems. Therefore, in 2011, we developed improved version of TrackWalker, called TrackWalker-II, that had low center of gravity, and longer tracks. To validate the mechanism, we conducted outdoor experiments in Mt. Asama again in Oct. 2011. In the field experiment, the robot traversed about 700m on a weak and steep slope (angle: 15-30deg, difference of elevation:160m). (Oct. 2011)

Robotic Observations in a volcanos using UAV and UGV on Mt.Asama 2014

Observation of an active volcano is very important to determine a strategy for estimating its eruptive activity and providing residents with an evacuation warning. Therefore, we have been conducting field tests of robotic observations in a volcanic area using a multi-rotor UAV (unmanned aerial vehicle) and a small ground robot. In this videoclip, we introduce our recent field test of cooperative motion between UAV and small UGV in Sept, 2014, on Mt. Asama. It is almost the same as the demonstration in Sept. 2013, shown the below. It used tether landing to improve its safety, and completed automatic delivering of the small ground robot. The ground robot was tele-operated 3km far away from the robot (Oct., 2014)

[Volcano] Development of Multi DOF Tracked Vehicle to Improve weak slope terrainability

In response to active volcano observation, our research group developed a novel multi-D.O.F. tracked vehicle, called ELF. The robot essentially consists of six tracks, and it has eleven actuators for locomotion and change of configuration. These actuators enable the robot to assume various configurations, which increase its ability to traverse weak and rough terrains in volcanic areas. In this movie-clip, the mechanism of Elf and its initial test in a volcanic field are introduced.
