Design, Fabrication and Gait Planning of Alligator-inspired Robot

چکیده
This paper reports design, fabrication, and gait planning based on high walk diagonal trot gait pattern of an alligatorinspired robot having eight degrees of freedom. Each leg of the robot described in this paper has two revolute joints representing the hip and knee respectively which are actuated by servo motors. The body of the robot was fabricated on a CO2 laser cutting machine. The 3D leg design was dividedinto two 2D components to enable manufacturing on a laser cutting machine to reduce fabrication cycle time. Finally, a general-purpose kinematics based model has been reported that is used to designand implement a high-walk gait on the developed robot.

Gait rehabilitation using body weight support on a treadmill is a recommended rehabilitation technique for neurological injuries, such as spinal cord injury. In this paper, a new robotic orthosis is presented for treadmill training. In the presented design the criteria such as low inertia of robot components, backdrivability, high safety and degrees of freedom based on human walking are conside...
متن کاملDynamics, Stability Analysis and Control of a Mammal-Like Octopod Robot Driven by Different Central Pattern Generators
In this paper, we studied numerically both kinematic and dynamic models of a biologically inspired mammal-like octopod robot walking with a tetrapod gait. Three different nonlinear oscillators were used to drive the robot’s legs working as central pattern generators. In addition, also a new, relatively simple and efficient model was proposed and investigated. The introduced model of the gait ge...
متن کاملStable Gait Planning and Robustness Analysis of a Biped Robot with One Degree of Underactuation
In this paper, stability analysis of walking gaits and robustness analysis are developed for a five-link and four-actuator biped robot. Stability conditions are derived by studying unactuated dynamics and using the Poincaré map associated with periodic walking gaits. A stable gait is designed by an optimization process satisfying physical constraints and stability conditions. Also, considering...
