This paper introduces an effect of tactile contact lens (TCL) on a rubber artificial skin layer with a strain gauge. The TCL is a non-mechatronic touch enhancing device. The TCL makes tactile perception of a surface undulation enhance when the TCL is traced a surface of a tactile target and laid between human skin and the surface traced. The rubber artificial skin layer with a strain gauge is a tactile...
Recently autonomous navigation technique for a mobile robot becomes very important. In a field of navigation, the technique for localization and mapping by laser range finder is one of the major interesting topic. In order to use the method, an environment map including navigation root is need to be prepared in advance. Then, it is necessary to travel the route once before to make the map and the...
The authors have developed the autonomous loading system by wheel loader. In this paper, we propose the path planning algorithm to optimally place both one unloading point and a set of several scooping points corresponding to that point. For simultaneously determining the set and streamlining the whole series of operations, this algorithm include the step of estimating the shape of rock piles collapsing...
The authors have developed an autonomous loading system for a wheel loader. In this paper, an algorithm is proposed to decide on both an optimized unloading point and several paths between the unloading point and several scooping points. The optimal unloading point that minimizes the total length of those paths has been obtained by using a three-dimensional configuration score space. In the configuration...
We have developed a wearable mobility and the interface to control the mobility, which is operated according to motions of lower legs of a wearer with the mobility. They are small wheeled mobile robots, which are mounted at sole of the both feet. In this paper, we introduce the developed mobility and propose a new interface to handle the mobility instinctively for the wearer with the mobility. Then,...
There is a demand of mining automation by heavy equipment in an open mine. Authors aim to automization of motion for wheel loader in scooping and loading operation. In this paper, we applied the optimization method by Genetic Algorithm to the path planning for the wheel loader on scooping and loading operation. We showed the quasi-optimized path and demonstrated by the miniature wheel loader robot.
Recently, e-assessment has become popular, and it is now technically possible for people to take exams at home. However, because the testing environment is dramatically different from the traditional one, new technologies are required to prevent cheating. Many studies have addressed testing environments where a keyboard and mouse are used as input devices, but few have focused on an environment using...
The objective of this research is to perform a long distance navigation in indoor environment, with a unicycle robot that has a wide-type wheel, and has a laser range finder installed on top of the robot. At present, there is no report for long distance navigation by unicycle robot in real indoor environment. We have developed a system that consists of two subsystems; “Balancing and Maneuvering System”...
The purpose of this research is to realize a motion along a straight line by a unicycle robot. The robot consists of upper and lower bodies connected with a joint. Our final target of this research is to realize navigation in indoor environment with the robot. In this paper, we describe the driving control system, and show results of the motion desired.
We are interested in making and control a small sized two-wheels bike robot and we aim to balance the robot and to lead it to desired direction only with automatic steering control. Our research purpose is to make an original small sized bike robot and to move the robot for over 300 meters in indoor corridors under the automatic steering control only. We report the making of the original small bike...
