A robust automated system to collect protein crystals for X-ray crystallography is presented. This system uses an ultraviolet imaging system based on commercial off-the-shelf components, a magnetically manipulated tool, and a resilient behavior-based controller. The system is validated by collecting over 350 polystyrene beads, used as crystal emulators, and transporting them 2 mm to a predefined goal...
In this paper, we present a holistic system for automating the motion of a rolling microrobot for protein crystal harvesting. The RodBot, which was introduced in previous work, is able to perform noncontact manipulation of microscopic objects such as fragile crystals by trapping them in an induced vortex fluid flow. Here, we are concerned with navigating the RodBot autonomously in a liquid environment...
In this work, a magnetic visual control system for automated protein crystal harvesting is proposed. The system consists of a rod-shaped microrobot, a magnetic actuation system and a visual control system. A rotating magnetic field induces the microrobot to roll on the supporting surface, thereby creating a vortex in a liquid environment. This vortex enables the robot to trap and transport even delicate...
