Industrial equipment, such as bulldozers, excavators, and cranes, requires human operation. Construction machines with better operability are necessary in order to improve productivity. The evaluation of such operational equipment is performed in order to obtain better operability, at the design stage, by sensory evaluation from a specific evaluator. Therefore, the design and evaluation of operational...
A lot of Industrial equipments need operations. Equipments such as excavators and cranes are evaluated by sensory evaluations of the specific evaluator at the design stage. Designs and evaluations of operated equipments depend on subjective evaluations. However, subjective evaluations require the skill of evaluation or a lot of sample data. In this paper, a quantitative evaluation is considered about...
Robots have been strongly demanded to substitute humans for tasks at dangerous places such as indoor and outdoor disaster sites or minefields. Most of these robots are remotely controlled by human operators with controllers which consist of joysticks and buttons. But we think it is an urgent issue to control robots more intuitively and quickly for this type of remote control systems. Therefore, the...
Manipulators, which are mounted on robots that substitute man at dangerous places like indoors and outdoors disaster sites or mine fields, have been mainly controlled by joysticks. However, joysticks are difficult to manipulate and complex tasks become hard to be done by operators because of a limit and discordance of controlled degree of freedom. Therefore, a controller with high operability like...
Detection of SF6 gas leakage from a gas insulated switchgear (GIS) has recently become an important issue from an environmental standpoint in addition to the demands for the insulating reliability. This paper describes a state-of-the-art gas leakage detection system, which consists of a high-performance gas pressure sensor and a new algorithm improving accuracy of the leakage rate calculation. The...
