Grasping of Deformable Objects. Building on the well-established form closure framework for holding rigid parts, Co-PI Goldberg introduced D-space (deformation space), a new framework for holding deformable parts [79]. This work consideres the class of deformable objects that can be modeled as linearly elastic polygons with a triangular nite element mesh, and denes the D-space of a part as the conguration space of all its mesh nodes. An object is then dened to be in deform closure when positive work is required to release the part from a grasp.

In many cases, the control basis representation facilitates the formation of schema. For example, a general plan to first locate an object, reach to it, and then grasp it (the sequence, localize- reach-!grasp) is independent of decisions about how to locate it, and with which arm and hand to grasp. In the control basis, the general plan is captured in a sequence of potential functions, {!|%}, that convey the intention to locate, reach, and then grasp. This is a form of declarative description of the task. The procedural details—locate the object with the eyes, reach with your left arm, and grasp with your left hand—can be deferred until run-time. These details are the sensors, ", and effectors, # , that will work best given a particular context.
Motion Planning for Robotic Medical Devices. Co-PIs Alterovitz and Goldberg developed motion planning algorithms for human-controlled and robot-assisted medical needle insertion procedures, such as, biopsies and brachytherapy cancer treatment [21, 13, 8, 23, 9, 14]. A key challenge physicians face when guiding needles is tissue deformations due to needle forces. Alterovitz and Goldberg introduced planning methods that use physically-based simulation of soft tissue deformation as a component of an optimization-based planner that minimizes placement error while avoiding obstacles in the tissue. They applied this approach to both traditional clinical needles [21, 14] as well as steerable needles, a new class of exible, bevel-tip needle, co-invented by Alterovitz and Goldberg with colleagues at Johns
