Comparison between different model of hexapod robot in fault-tolerant gait
نویسندگان
چکیده
This paper presents a gait analysis of the equilateral hexagonal model of hexapod robot. Mathematical analysis has been made on mobility, fault-tolerance, and stability. A comparison with the rectangular model of hexapod robot is also given, and it has shown that the hexagonal model shows better turning ability, a higher margin of stability during the fault-tolerant gait, and greater stride length in certain conditions.

The Offset Model of a Hexapod Robot and the Effect of the Offset Parameter
Generally, it is claimed that hexapod walking robots are superior to others. However, in some conditions hexapod suffers from stability problems. To solve the problem of stability, this paper proposes a new gait model of hexapod robot named offset model and also investigates the effects of morphological factor of hexapod robots on their locomotion. A comparison between the offset model and gene...
متن کاملFault-Tolerant Locomotion of the Hexapod Robot - Systems, Man and Cybernetics, Part B, IEEE Transactions on
In this paper, we propose a scheme for fault detection and tolerance of the hexapod robot locomotion on even terrain. The fault stability margin is defined to represent potential stability which a gait can have in case a sudden fault event occurs to one leg. Based on this, the fault-tolerant quadruped periodic gaits of the hexapod walking over perfectly even terrain are derived. It is demonstra...
متن کاملImproving the Navigability of a Hexapod Robot using a Fault-Tolerant Adaptive Gait
This paper encompasses a study on the development of a walking gait for fault tolerant locomotion in unstructured environments. The fault tolerant gait for adaptive locomotion fulfills stability conditions in opposition to a fault (locked joints or sensor failure) event preventing a robot to realize stable locomotion over uneven terrains. To accomplish this feat, a ...
متن کاملA 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...
متن کاملOptimal 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...
