Safe tree felling using expansion agentSpringer Science and Business Media LLC - Tập 4 - Trang 1-9 - 2017
Chyon Hae Kim, Hiroaki Abe, Akio Numakura, Jyunpei Koyama, Yukio Takahashi
We discuss about safe tree felling methods. In previous work, tree felling robots that were equipped with cutting instruments have been investigated in order to keep workers’ safety. However, these robots may take damage when trees fall down against them. We propose a tree felling framework that maintains the workers and robots both in safe. In the proposed framework, a robot inserts a slow-acting...... hiện toàn bộ
Structurally isolated photoactuation of graphene-mixed temperature-responsive hydrogels in soft-rigid series structureSpringer Science and Business Media LLC - Tập 6 - Trang 1-9 - 2019
Tomoki Watanabe, Yoshiyuki Yokoyama, Takeshi Hayakawa
This paper presents fabrication and actuation methods for a soft microrobot with a hybrid structure composed of soft microactuators and a rigid supporting body. This hybrid structure enables actuation of the microrobot with independent driving of multiple actuators to provide complex movement like that of living microorganisms. We use the temperature-responsive hydrogel poly(N-isopropylacrylamide)...... hiện toàn bộ
Assessment of a tracked vehicle’s ability to traverse stairsSpringer Science and Business Media LLC - Tập 3 - Trang 1-13 - 2016
Daisuke Endo, Keiji Nagatani
In some surveillance missions in the aftermath of disasters, the use of a teleoperated tracked vehicle contributes to the safety of rescue crews. However, because of its insufficient traversal capability, the vehicle can become trapped upon encountering rough terrain. This may lead to mission failure and, in the worst case, loss of the vehicle. To improve the success rate of such missions, it is v...... hiện toàn bộ
Development of ROS-TMS 5.0 for informationally structured environmentSpringer Science and Business Media LLC - Tập 5 - Trang 1-11 - 2018

An informationally structured environment (ISE) is a key technology for realizing service robots in daily life in the near future. In ISE, the information of the service robot and its surroundings is structured and provided to the robot on time and on demand. We started the development of a management system for ISE named TMS (Town Management System) in Robot Town Project in 2005. Since then we ar...... hiện toàn bộ
Compound locomotion control system combining crawling and walking for multi-crawler multi-arm robot to adapt unstructured and unknown terrainSpringer Science and Business Media LLC - Tập 5 - Trang 1-17 - 2018

How to improve task performance and how to control a robot in extreme environments when just a few sensors can be used to obtain environmental information are two of the problems for disaster response robots (DRRs). Compared with conventional DRRs, multi-arm multi-flipper crawler type robot (MAMFR) have high mobility and task-execution capabilities. Because, crawler robots and quadruped robots hav...... hiện toàn bộ
Bộ điều khiển nối tiếp admittance–impedance cho việc mở rộng kiểm soát lực mạnh mẽ và ổn định hơn Dịch bởi AI Springer Science and Business Media LLC - Tập 9 - Trang 1-16 - 2022
Takuto Fujiki, Kenji Tahara
Để kiểm soát một robot thực hiện công việc hợp tác giữa con người và robot, không chỉ vị trí mà còn lực cũng cần được kiểm soát từ góc độ tương tác giữa con người và robot. Thêm vào đó, khi một robot được sử dụng cho việc lắp ghép và xử lý, những nhiệm vụ mà thường được thực hiện bởi những con người có kinh nghiệm, việc kiểm soát lực nắm và lực tác dụng bởi các khớp có thể tạo ra những chuyển động...... hiện toàn bộ

Hopping path planning in uncertain environments for planetary explorationsSpringer Science and Business Media LLC - Tập 9 Số 1 - 2022
Kenkichi Sakamoto, Takashi Kubota
AbstractHopping robots, called hoppers, are expected to move on rough terrains, such as disaster areas or planetary environments. The uncertainties of the hopping locomotion in such environments are high, making path planning algorithms essential to traverse these uncertain environments. Planetary surface exploration requires to generate a path which minimises the ...... hiện toàn bộ
