Adaptive Autonomous Navigation of Multiple Optoelectronic Microrobots in Dynamic Environments

Laurent Mennillo, Christopher Bendkowski, Mohamed Elsayed, Harrison Edwards, Shuailong Zhang, Vijay Pawar +3

RA-L 2022

The optoelectronic microrobot is an advanced light-controlled micromanipulation technology which has particular promise for collecting and transporting sensitive microscopic objects such as biological cells. However, wider application of the technology is currently limited by a reliance on manual co

Autonomous object harvesting using synchronized optoelectronic microrobots

Christopher Bendkowski, Laurent Mennillo, Tao Xu, Mohamed Elsayed, Filip Stojic, Harrison Edwards +6

IROS 2021poster

Optoelectronic tweezer-driven microrobots (OETdMs) are a versatile micromanipulation technology based on the application of light induced dielectrophoresis to move small dielectric structures (microrobots) across a photoconductive substrate. The microrobots in turn can be used to exert forces on sec…

CHESS - Calibrating the Hand-Eye Matrix With Screw Constraints and Synchronization

Krittin Pachtrachai, Francisco Vasconcelos, George Dwyer, Vijay Pawar, Stephen Hailes, Danail Stoyanov

RA-L 2018

Hand-eye calibration is a classic problem in robotics that aims to find the transformation between two rigidly attached reference frames, usually a camera and a robot end-effector or a motion tracker. Most hand-eye calibration techniques require two data streams, one containing the eye (camera) moti

A Continuum Robot and Control Interface for Surgical Assist in Fetoscopic Interventions

George Dwyer, François Chadebecq, Marcel Tella-Amo, Christos Bergeles, Efthymios Maneas, Vijay Pawar +6

RA-L 2017

Twin-twin transfusion syndrome requires interventional treatment using a fetoscopically introduced laser to sever the shared blood supply between the fetuses. This is a delicate procedure relying on small instrumentation with limited articulation to guide the laser tip and a narrow field of view to

Hand-eye calibration for robotic assisted minimally invasive surgery without a calibration object

Krittin Pachtrachai, Max Allan, Vijay Pawar, Stephen Hailes, Danail Stoyanov

IROS 2016poster

In a robot mounted camera arrangement, hand-eye calibration estimates the rigid relationship between the robot and camera coordinate frames. Most hand-eye calibration techniques use a calibration object to estimate the relative transformation of the camera in several views of the calibration object…
