Abstract
Disclosed is a mobile robot adapted to traverse vertical obstacles. The robot comprises a frame and at least one wheel positioned in a front section of the robot, at least one middle wheel positioned in a middle section of the robot, at least one back wheel positioned in a back section of the robot, and at least one further wheel in the front, middle or back of the robot. The robot also comprises at least one motor-driven device for exerting a downward and/or upward force on the middle wheel and at least two motors for driving the wheels and the motor-driven device. Also disclosed is a method of climbing using a mobile robot as disclosed.
Claims31
A mobile robot adapted to traverse at least vertical obstacles, the robot comprising a frame structure having a front end and a back end, and further having a front section, a middle section, and a back section, the robot further comprising:
- (a) at least one front wheel positioned in the front section of the robot and extending beyond it in the front, at least one back wheel positioned in the back section of the robot, and at least one middle wheel positioned in the middle section of the robot;
- (b) at least one further wheel positioned either in the front section, middle section and/or back section of the structure;
- (c) a motor-driven device for exerting a downward and/or upward force with respect to the ground, selectively on the at least one middle wheel;
- and
- (d) at least two motors, each of which being adapted to drive the wheels and/or the motor-driven device,
- wherein the mobile robot is configured such that the relative order of the at least one back wheel and the at least one middle wheel is maintained while the robot traverses at least vertical obstacles.
