Abstract
We have proposed and developed a new quadruped walking robot with a spherical shell, called “QRoSS”. QRoSS is a transformable robot that can store its legs in the spherical shell. The shell not only absorbs external forces from all directions, but also improves mobile performance because of its round shape. In rescue operations at a disaster site, carrying robots into a site is dangerous for operators because doing so may result in a second accident. If QRoSS is used, instead of being carried in, robots are thrown in, making the operation safe and easy. We developed the QRoSS series and conducted basic experiments to verify performance, which includes landing, rising and walking through a series of movements. This paper reports details of a mechanical design to improve walking performance and development of the QRoSS V prototype model. We discuss the rising operation and performance of climbing over a high vertical step.
Highlights
Rescue robots have recently been developed as a way to gather information on rough terrain environments, such as disaster sites where it is difficult for people to enter
The actual height of the step that QRoSS V can climb over is not very high compared with previous research because its body is Conclusion We proposed a quadruped walking robot (QRoSS) with a spherical shell and developed the fifth prototype model
QRoSS V is a transformable robot and can change from its storage state, in which four legs are stored in the spherical shell, to deploy the legs outside the shell
Summary
Rescue robots have recently been developed as a way to gather information on rough terrain environments, such as disaster sites where it is difficult for people to enter. The rescue robots have a problem in that they must travel from a safe area to the investigation sites. This uselessly consumes limited power resources, thereby shortening operation time. If robots can be thrown into an uneven terrain from a safe area, consumption of electricity for travel is decreased, and operators will be safe with no need to enter the danger zone.
