Dynamic movement primitive
WebOct 5, 2011 · General-purpose autonomous robots must have the ability to combine the available sensorimotor knowledge in order to solve more complex tasks. Such knowledge is often given in the form of movement primitives. In this paper, we investigate the problem of sequencing of movement primitives. We selected nonlinear dynamic systems as the … WebDynamic Movement Primitives (DMPs) is a general framework for the description of demonstrated trajectories with a dynamical system. For example, in its simplest form, a …

WebThe movement representation supports discrete and rhythmic movements and in particular includes the dynamic movement primitive approach as a special case. We demonstrate the feasibility of the movement representation in three multi-task learning simulated scenarios. First, the characteristics of the proposed representation are illustrated in a ... WebMar 30, 2024 · Obstacle avoidance for Dynamic Movement Primitives (DMPs) is still a challenging problem. In our previous work, we proposed a framework for obstacle avoidance based on superquadric potential functions to represent volumes. In this work, we extend our previous work to include the velocity of the system in the definition of the potential. Our …
WebWe learn a dynamic constraint frame aligned to the direction of desired force using Cartesian Dynamic Movement Primitives. In contrast to approaches that utilize a fixed constraint frame, our ... WebSep 3, 2024 · Figure 1 shows an example of a possible search tree for the case where the movement library contains only 3 primitive movements. By using the search tree, we can now determine the sequence of primitives that minimizes the total cost. After each new critical point is discovered, the tree grows a level in depth and the node values are …
WebAug 28, 2024 · Dynamic Movement Primitives (DMPs) is a framework for learning a point-to-point trajectory from a demonstration. Despite being widely used, DMPs still present some shortcomings that may limit their usage in real robotic applications. Firstly, at the state of the art, mainly Gaussian basis functions have been used to perform function approximation. … Web346 subscribers.
