چکیده

In modern day disaster recovery mission has become one of the top priorities in any natural disaster management regime. Smart autonomous robots may play a significant role in such missions, including search for life under earth quake hit rubbles, Tsunami hit islands, de-mining in war affected areas and many other such situations. In this paper current state of many walking robots are compared and advantages of hexapod systems against wheeled robots are described. In our research we have selected a hexapod spider robot; we are developing focusing mainly on efficient navigation method in different terrain using apposite gait of locomotion, which will make it faster and at the same time energy efficient to navigate and negotiate difficult terrain. This paper describes the method of terrain negotiation navigation in a hazardous field. Keywords—Walking robots, locomotion, hexapod robot, gait, hazardous field.

Continuous free-crab gaits for hexapod robots on a natural terrain with forbidden zones: An application to humanitarian demining

Autonomous robots are leaving the laboratories to master new outdoor applications, and walking robots in particular have already shown their potential advantages in these environments, especially on a natural terrain. Gait generation is the key to success in the negotiation of natural terrain with legged robots; however, most of the algorithms devised for hexapods have been tested under laborat...

Image-based Method for Determining Better Walking Strategies for Hexapods

An intelligent walking strategy is vital for multi-legged robots possessing no a priori information of an environ‐ ment when traversing across discontinuous terrain. Sixlegged robots outperform other multi-legged robots in static and dynamic stability. However, hexapods require careful planning to traverse across discontinuous terrain. A hexapod walking strategy can be accomplished using a visi...

Multi-agent Application: A Novel Algorithm for Hexapod Robots Gait Transitions

In this paper, a gait transition method has proposed that allows a group of multi-agent hexapod robot to switch from one gait to another gait with stable condition, during different terrain navigation. Typical gaits of locomotion are analyzed for hexapod robot. Hexapod robots frequently operate various gaits to locomote over a variety of surfaces. To enable locomotion in a changing surface, hex...

Optimal Fault Tolerant Gait Sequence Of The Hexapod Robot With Overlapping Reachable Areas And Crab - Systems, Man and Cybernetics, Part A, IEEE Transactions on

This paper extends the authors’ previous results on fault tolerant locomotion of the hexapod robot on even terrain by relaxing nonoverlap of redefined reachable cells of legs and considering crab walking. It is shown that in fault tolerant locomotion two adjacent legs of the hexapod robot can have overlapping redefined reachable cells with each other and consequently the stride length of the ga...

A fault tolerant gait for a hexapod robot over uneven terrain

The fault tolerant gait of legged robots in static walking is a gait which maintains its stability against a fault event preventing a leg from having the support state. In this paper, a fault tolerant quadruped gait is proposed for a hexapod traversing uneven terrain with forbidden regions, which do not offer viable footholds but can be stepped over. By comparing performance of straight-line mo...
