Design, Implementation, and Testing of a Force-Sensing Quadrupedal Laminate Robot

Description
In this article we present a low-cost force-sensing quadrupedal laminate robot platform. The robot has two degrees of freedom on each of four independent legs, allowing for a variety of motion trajectories to be created at each leg, thus creating a rich control space to explore on a relatively low-cost…

In this article we present a low-cost force-sensing quadrupedal laminate robot platform. The robot has two degrees of freedom on each of four independent legs, allowing for a variety of motion trajectories to be created at each leg, thus creating a rich control space to explore on a relatively low-cost robot. This platform allows a user to research complex motion and gait analysis control questions, and use different concepts in computer science and control theory methods to permit it to walk. The motion trajectory of each leg has been modeled in Python. Critical design considerations are: the complexity of the laminate design, the rigidity of the materials of which the laminate is constructed, the accuracy of the transmission to control each leg, and the design of the force sensing legs.

In this article we present a program that is supplemental to a low-cost force-sensing quadrupedal laminate robot platform previously developed by Ben Shuch. The robot has four legs with two degrees of freedom apiece. Each leg is a four-bar mechanism controlled by two servo motors. The program that has been developed allows the user to predict the force distribution of the robot based on its configuration and the angle of the ground it is standing on. Through the use of this program, future students working on research involving this robot will be able to calculate the force distribution of the robot based on its configuration and generate ideal configurations of the robot using data gathered from force sensors attached to its feet.
