Forward and Inverse Dynamics of a Unicycle-Like Mobile Robot

Abstract: In this research work, a new method for solving forward and inverse dynamic problems of mechanical systems having an underactuated structure and subjected to holonomic and/or nonholonomic constraints is developed. The method devised in this paper is based on the combination of the Udwadia-Kalaba Equations with the Underactuation Equivalence Principle. First, an analytical method based on the Udwadia-Kalaba Equations is employed in the paper for handling dynamic and control problems of nonlinear nonholonomic me… Show more

“…One of the significant and mostly used ML approaches is deep reinforcement learning (DRL) which applies two actor-critic networks to adjust Markov decision processes according to the maximization of cumulative rewards. Unlike supervised/unsupervised learning, DRL receives samples without labels and just considers reward functions in determination of selected policy and state-action pairs [8], [9]. The advantage of DRL over the other ML methods is application of minimal prior information to reach optimum control [10][11][12][13][14][15].…”

“…However, since we use the same robot manipulator, we change the mobile platform to find which one is the most appropriate to be used in the construction site. In particular, we test the following configurations: unicycle, car-like and four wheeled omnidirectional with mecanum wheels [34,35]. We test the performance of the mobile manipulator mounted on the three different platforms in terms of error and effort, when printing several types of building elements.…”
