چکیده

In this work, we consider the problem of manipulating a polygonal object through an obstacle-filled environment using only push interactions, or nudges. For this problem, we propose a manipulation planner that could handle multiple queries and offer solutions with a higher probability of success than traditional planners, especially in the face of uncertainty. We have implemented our approach in simulation, and offer some preliminary results to demonstrate the technique.

Planar Molecular Dynamics Simulation of Au Clusters in Pushing Process

Based on the fact the manipulation of fine nanoclusters calls for more precise modeling, the aim of this paper is to conduct an atomistic investigation for interaction analysis of particle-substrate system for pushing and positioning purposes. In the present research, 2D molecular dynamics simulations have been used to investigate such behaviors. Performing the planar simulations can provide a ...

Stable Prehensile Pushing: In-Hand Manipulation with Alternating Sticking Contacts

This paper presents an approach to in-hand manipulation planning that exploits the mechanics of alternating sticking contact. Particularly, we consider the problem of manipulating a grasped object using external pushes for which the pusher sticks to the object. Given the physical properties of the object, frictional coefficients at contacts and a desired regrasp on the object, we propose a samp...

A mild protocol for the preparation of 2-amino-dihydropyrano[3,2-b] pyran-3-carbonitriles via cobalt nanoparticles-catalyzed multi-component reaction in water

An improved rapid one-pot and green synthesis of substituted pyranopyranes by condensing Kojic acid, malononitrile, and different aldehydes and using a catalytic amount of cobalt nanoparticles as green and reusable catalyst is reported for the first time. The reaction proceeds in aqueous media at ambient temperature. Furthermore, the structural and morphological study of the cobalt nanoparticle...

Sampling-Based Planning and Local Reactive Strategies for Environment Manipulation

We address the motion planning problem for a single robot that manipulates passive objects in an otherwise static environment. We handle uncertainties in passive object responses while abstracting their dynamics by creating a roadmap that encodes the possible passive object responses. The robot extracts reference paths from the passive roadmap to plan approaching motions with an active roadmap....

Optical micromanipulation of active cells with minimal perturbations: direct and indirect pushing.

The challenge to wide application of optical tweezers in biological micromanipulation is the photodamage caused by high-intensity laser exposure to the manipulated living systems. While direct exposure to infrared lasers is less likely to kill cells, it can affect cell behavior and signaling. Pushing cells with optically trapped objects has been introduced as a less invasive alternative, but th...
