Planning for Complex Non-prehensile Manipulation Among Movable Objects by Interleaving Multi-Agent Pathfinding and Physics-Based Simulation

no code implementations23 Mar 2023 Dhruv Mauria Saxena, Maxim Likhachev

In particular, our motivation is to allow the robot to reason over and consider non-prehensile rearrangement actions that lead to complex robot-object and object-object interactions where multiple objects might be moved by the robot simultaneously, and objects might tilt, lean on each other, or topple.

A fine discretisation allows for better approximations of the continuous search space, but makes the search for a solution more computationally costly.

Manipulation Planning Among Movable Obstacles Using Physics-Based Adaptive Motion Primitives

no code implementations8 Feb 2021 Dhruv Mauria Saxena, Muhammad Suhail Saleem, Maxim Likhachev

Unfortunately, it is infeasible to query the simulator for thousands of actions that need to be evaluated in a typical planning problem as each simulation is time-consuming.
