In artificial forest, thinning is essential for maintaining the forest normal. Usually, human power or winch are used in the case of carrying short distance. However, it involves danger and a lot of efforts to carry thinnings by those means. Add to that, those means limit the distance to be able to carry the thinnings. Sometimes, tractor is also used, but it is dangerous to drive rough terrain on it because there is a possibility to overturn. Therefore, we propose Non-boarding operation and hyper-tether. Non-boarding operation avoid the danger of vehicle tumbling accident previously and hyper tether enables to intuitive operation. This robot consists of several units which has two wheels and both wheels are able to drive and steer individually, so this system is all wheel drive and all wheel steer in the total.
