Transferring Kinesthetic Demonstrations across Diverse Objects for Manipulation Planning
Dibyendu Das, Aditya Patankar, Nilanjan Chakraborty +2
Given a demonstration of a complex manipulation task, such as pouring liquid from one container to another, we seek to generate a motion plan for a new task instance involving obje…
Synthesizing Grasps and Regrasps for Complex Manipulation Tasks
Aditya Patankar, Dasharadhan Mahalingam, Nilanjan Chakraborty
In complex manipulation tasks, e.g., manipulation by pivoting, the motion of the object being manipulated has to satisfy path constraints that can change during the motion. Therefo…
Screw Geometry Meets Bandits: Incremental Acquisition of Demonstrations to Generate Manipulation Plans
Dibyendu Das, Aditya Patankar, Nilanjan Chakraborty +2
In this paper, we study the problem of methodically obtaining a sufficient set of kinesthetic demonstrations, one at a time, such that a robot can be confident of its ability to pe…
A General Formulation for Path Constrained Time-Optimized Trajectory Planning with Environmental and Object Contacts
Dasharadhan Mahalingam, Aditya Patankar, Riddhiman Laha +3
A typical manipulation task consists of a manipulator equipped with a gripper to grasp and move an object with constraints on the motion of the hand-held object, which may be due t…
Computing a Task-Dependent Grasp Metric Using Second Order Cone Programs
Amin Fakhari, Aditya Patankar, Jiayin Xie +1
Evaluating a grasp generated by a set of hand-object contact locations is a key component of many grasp planning algorithms. In this paper, we present a novel second order cone pro…
Motion and Force Planning for Manipulating Heavy Objects by Pivoting
Amin Fakhari, Aditya Patankar, Nilanjan Chakraborty
Manipulation of objects by exploiting their contact with the environment can enhance both the dexterity and payload capability of robotic manipulators. A common way to manipulate h…
