Function Based Sim-to-Real Learning for Shape Control of Deformable Free-form Surfaces

RSS 2024poster

For the shape control of deformable free-form surfaces, simulation plays a crucial role in establishing the mapping between the actuation parameters and the deformed shapes. The differentiation of this forward kinematic mapping is usually employed to solve the inverse kinematic problem for determini…

Singularity-Aware Motion Planning for Multi-Axis Additive Manufacturing

RA-L 2021

Multi-axis additive manufacturing enables high flexibility of material deposition along dynamically varied directions. The Cartesian motion platforms of these machines include three parallel axes and two rotational axes. Singularity on rotational axes is a critical issue to be tackled in motion plan

Plant Phenotyping by Deep-Learning-Based Planner for Multi-Robots

RA-L 2019

Manual plant phenotyping is slow, error prone, and labor intensive. In this letter, we present an automated robotic system for fast, precise, and noninvasive measurements using a new deep-learning-based next-best view planning pipeline. Specifically, we first use a deep neural network to estimate a

Steering micro-robotic swarm by dynamic actuating fields

ICRA 2016

We present a general solution for steering microrobotic swarm by dynamic actuating fields. In our approach, the motion of micro-robots is controlled by changing the actuating direction of a field applied to them. The time-series sequence of actuating field's directions can be computed automatically.

Computing stable contact interface for customized surgical jigs

ICRA 2015poster

This paper presents a framework to compute stable contact interfaces for automatically designing customized jigs used in bone surgeries. Given the surface model of a bone represented by polygonal meshes, we find out a small region on the surface to be used as the interface of a customized jig so tha…

Photometric Stereo With Near Point Lighting: A Solution by Mesh Deformation

CVPR 2015poster

We tackle the problem of photometric stereo under near point lighting in this paper. Different from the conventional formulation of photometric stereo that assumes parallel lighting, photometric stereo under the near point lighting condition is a nonlinear problem as the local surface normals are co…
