Combining the advantages of active and passive walking robots, we have developed a novel active biped walking robot with only six DoFs. The robot is built with six 1-DoF joint modules and two wheels as the feet. It achieves locomotion in special gaits different from those of traditional biped robots. In this paper, this novel biped robot is introduced, and four walking gaits, namely turning-around...
A novel biped robot that can climb poles, trusses and trees for high-rise missions has been recently developed. Consisting of an arm as the main body and two grippers mounted at the two ends as the end-effectors, the robot has both climbing function and manipulating function. One key issue with the robot is that its gripper must grasp the object firmly to support the whole robot when it performs climbing...
Most of current biped robots are active walking platforms. Though they have strong locomotion ability and good adaptability to environments, they have a lot of degrees of freedom (DoFs) and hence result in complex control and high energy consumption. On the other hand, passive or semi-passive walking robots require less DoFs and energy, but their walking capability and robustness are poor. To overcome...
Although a large number of wall-climbing robots have been developed in the past decades, most of them suffer from shortcomings such as poor ability to omni-directional locomotion, lower capability to transit between walls and to negotiate obstacles on the walls. To overcome these drawbacks, we have developed a novel biped wall-climbing robot - W-Climbot using modularization method. Consisting of an...
Modules have been widely used in the development of re-configurable robots and snake-like robots. Modular methodology can also be applied in design of other robots. To build robots flexibly and quickly with low costs, we have developed two basic joint modules and several functional modules including grippers, suckers and wheels/feet as end-effectors. In this paper, we introduce the development of...
Inspired by the motion patterns of inchworms, a miniature biped climbing robot is developed with modularization method for some tedious and dangerous high-rise tasks. This inchworm-like mini-robot consists of several modules including I-typed joint modules, T-typed joint modules, and gripper modules, which are all driven by small RC servo motors. In this paper, the development of the robot prototype...
For high-rise work in fields such as agriculture, forestry and architecture, and inspired by the climbing motion of inchworms, chimpanzees, and sloths, we have developed a biped climbing robot - Climbot. Consisting of five 1-DOF joint modules in series and two special grippers at the ends, Climbot is capable of grasping objects and climbing poles, trees and trusses. In this paper, we first introduce...
Modules have been widely used in development of various robots including re-configurable robots and snake-like robots. To build robotic systems more flexibly and quickly with low costs of manufacturing and maintenance, we have developed two basic types, which are called T-type and I-type, of robotic joint modules with one degree of freedom for general purpose. The modules are designed to be compact,...
