Title: Novel wall-climbing robot mechanism

Applicant: Shenyang Inst Automation (CN)

Patent number: CN201105774 (Y)

Publication date: August 27, 2008

Abstract

The utility model relates to a mobile robot mechanism, in particular to a novel climbing robot mechanism, which comprises bodies, a connecting rod and sucked feet, wherein, the two bodies are, respectively, connected with the sucked feet and adopt a rotating joint to be connected by the connecting rod, thus realizing the relative rotation of the two bodies, wherein, one body is provided with the rotating joint which is driven by a motor and is arranged vertically, and the other body is provided with a mobile joint which is driven by a motor and is arranged vertically and the rotating joint arranged vertically, thus realizing the rotation in place of the whole robot mechanism and the scaling of the sucked feet; the movement and the adjustment of the posture of the robot can be realized by the relative rotation of the two bodies and the alternating sucking and releasing of the two sucked feet; and by combining the advantages of fast moving speed of a wheeled mechanism and strong obstacle-surmounting capability of a foot-typed mechanism, the mobile robot mechanism realizes the purposes of fast moving speed, light weight, low energy consumption, and strong motor ability.

Title: Agricultural Automation System With Field Robot

Applicant: Deere & Co (US); Faivre Stephen Michael (US); Anderson Noel Wayne (US); Stelford Mark William (US)

Patent number: WO2008136804 (A1)

Publication date: November 13, 2008

Abstract

An agricultural automation system for use in an agricultural area includes an implement caddy carrying a plurality of implements, an elongate transport structure, and a field robot movable along the elongate transport structure. The field robot includes an arm, movable in at least one direction different from the movement along the elongate transport structure. The field robot interfaces with the implement caddy for coupling the arm, with at least one selected implement, such as a tool or sensor.

Title: Mobile robot for ice and snow surface

Applicant: Shenyang Inst Automation (CN)

Patent number: CN201148179 (Y)

Publication date: November 12, 2008

Abstract

The utility model relates to the advanced manufacturing and automation technology field, concretely relates to a mobile robot which can be used on ice and snow surface, comprising a carriage body, two travel mechanisms and four swing arm mechanisms. The travel mechanisms are installed at both sides of the carriage body and are symmetric left to right. The four swing arm mechanisms are arranged at the front and back of the carriage body and are symmetric left to right. The driving chain wheel of the travel mechanism is connected with the driving axle in front of the carriage body. The output shaft installed behind the carriage body is connected with a driven chain wheel by a bearing. The swing arm of the swing arm mechanism is connected with the output shaft of the carriage body. The swing arm chain wheel in front of the swing arm mechanism is bolt-connected the driving chain wheel of the travel mechanism by a shaft sleeve. And the swing arm chain wheel at the back of the swing arm mechanism is bolt-connected with the driven chain wheel of the travel mechanism by a shaft sleeve. The mobile robot can work in low temperature environment, has autonomous slope climbing and obstacle negotiation abilities such as crossing over ice crack, surmounting snow slop and snow dune and so on.

Title: Autonomous Mobile Robot

Applicant: iRobot Corp (US)

Patent number: US2008294288 (A1)

Publication date: November 27, 2008

Abstract

A mobile robot is equipped with a range finder and a stereo vision system. The mobile robot is capable of autonomously navigating through urban terrain, generating a map based on data from the range finder and transmitting the map to the operator, as part of several reconnaissance operations selectable by the operator. The mobile robot employs a Hough transform technique to identify linear features in its environment, and then aligns itself with the identified linear features in order to navigate through the urban terrain; while at the same time, a scaled vector field histogram technique is applied to the combination of range finder and stereo vision data to detect and avoid obstacles the mobile robot encounters when navigating autonomously. Also, the missions performed by the mobile robot may include limitation parameters based on distance or time elapsed, to ensure completion of the autonomous operations.

Title: Dual Tracked Mobile Robot For Motion In Rough Terrain

Applicant: Ariel University Res and Dev C (IL); Univ Ben Gurion (IL)

Patent number: EP1957349 (A1)

Publication date: August 20, 2008

Abstract

The invention is an autonomous dual tracked mobile robot system comprising two or more tracked driving units configured to travel in tandem and a separate mechanical linkage, which joins each of the mobile units to the unit immediately preceding and following it, and enables efficient power transmission between the two driving units. Each of the mechanical linkages comprises one connecting bar and three revolute joints located on each of the adjacent units and a connecting beam that connects the connecting bar on one of the units with the connecting bar on the adjacent unit.

Title: Four-foot creeping robot

Applicant: University of Shenyang Technology (CN)

Patent number: CN201120913 (Y)

Publication date: September 24, 2008

Abstract

The utility model relates to a quadruped crawling robot, in particular to a micro-miniaturized crawling robot and mobile robot with extraordinarily high movement stability and good adaptability to the environment which can perform various extreme operations in stead of human beings. The quadruped crawling robot adopts the structure that a single-chip microcomputer (2), a power source (3), a task planning device (4) and motors (13) are installed on a robot body (1), the power source (3) and the task planning device (4) are controlled by the single-chip microcomputer (2), the four motors (13) are controlled by the task planning device (4) and, respectively, control the movements of first arms of a leg (5), a leg (6), a leg (7), and a leg (8), thus ensuring the first arms to rotate within the specified angles; and second arms and third arms controlled by the motors are, respectively, installed on the four legs as well. The static stability of the quadruped crawling robot is good, the dynamic walking can be realized, the development of the industrial robots can be realized on the basis of the quadruped crawling robot, the transportation of small parts can be accomplished, and the quadruped crawling robot can perform operations which cannot be accomplished by the human beings.

Title: Mobile Robot

Applicant: Toyota Motor Co Ltd (JP)

Patent number: KR20080093460 (A)

Publication date: October 21, 2008

Abstract

A technique to wholly recognize the surrounding environment may be provided by excluding unknown environment which arises due to parts of a body of a robot hindering the sight of the robot during operations. The robot of the present invention is provided with a body trunk including head and torso, at least one connected member that is connected to the body trunk by a joint in which a driving mechanism is provided, a body trunk side camera that is arranged on the body trunk, and a connected member side camera that is arranged on the connected member. Further, the robot is provided with a composite image creation unit that creates composite image of a body trunk side image taken by the body trunk side camera and a connected member side image taken by the connected member side camera, such that a part of the body trunk side image is replaced with a part of the connected member side image so as to exclude the connected member from the body trunk side image.
