Mechanics of six-legged runners.
Six-legged pedestrians, cockroaches, use a running gait during locomotion. The gait was defined by measuring ground reaction forces and mechanical energy fluctuations of the center of mass in Blaberus discoidalis (Serville) as they travelled over a miniature force platform. These six-legged animals produce horizontal and vertical ground-reaction patterns of force similar to those found in two-,...
متن کاملSix-Legged Robot Gait Analysis
This paper includes results of investigations of real six-legged robot. By the name of hexapod we call a robot that walks on six legs. Due to specific construction of legs, each leg has 3 degrees of freedom, prototype constructed by us allows to model gait of reptiles and insects. Presented system of rotation angle of each of the cells (servos) allows to analyze every single type of the movemen...
متن کاملAnalysis of Six-legged Walking Robots
In the present paper, an attempt has been made to carry out kinematic and dynamic analysis of a six-legged robot. A three-revolute (3R) kinematic chain has been chosen for each leg mechanism in order to mimic the leg structure of an insect. Denavit–Hartenberg (D-H) conventions are used to perform kinematic analysis of the six-legged robot. The direct and inverse kinematic analysis for each leg ...
متن کاملGait Analysis for Six-Legged Robots
We present a general method for the analysis of the gaits used by a six-legged robot independently of the mechanism used to generate the gait. The gait state of the robot is de ned as a function of the last executed steps and several classes of gait states as well as the transitions between them are identi ed. As an example, we apply our method to the well-know wave gaits (the most e cient and ...
متن کاملThe Effect of Six-Legged Concrete Elements on Hydraulic Jump Characteristics
In the present study, the six legged concrete (SLC) elements are placed at the bed of a flume downstream of a chute in different layouts, densities and number of longitudinal rows of SLC elements. Each test was run for different flow conditions (Froude numbers ranged 5.3 to 8.1). During each test, the water surface profile, the roller length and the jump length measured. Applying the experimen...
