Curved-Spoke Tri-Wheel Mechanism for Fast Stair-Climbing
2019
IEEE Access
Preserved Fulltext
In this paper, a curved spoke-based tri-wheel mechanism is proposed for fast and robust stair-climbing. The goal speed of stair-climbing is similar to the human speed for variously sized stairs. ...
The proposed wheel system is composed of a tri-wheel mechanism with a curved spoke, wherein the dimensions of the mechanism are determined based on a kinematic analysis. ...
CONCLUSION This paper presented a robot design for stair-climbing using a curved-spoke tri-wheel mechanism. Using the mechanism, the robot can climb stairs at a high speed. ...

In contrast to most hybrid platforms that have separate mechanisms and actuators for wheels and legs, this robot is implemented with a unique transformation mechanism that directly switches the morphology ...
The performance of the robot is evaluated in various scenarios, including driving and turning in wheeled mode, driving, step and bar crossing, irregular terrain passing, and stair climbing in legged mode ...
ACKNOWLEDGMENT The authors would like to thank National Instruments' Taiwan Branch for their kind support of this study through equipment and technical consulting. ...
