The DARPA Robotics Challenge (DRC) requires teams to integrate mobility, manipulation, and perception to accomplish several disaster-response tasks. We describe our hardware choices and software architecture, which enable human-in-the-loop control of a 28 degree-of-freedom ATLAS humanoid robot over a limited bandwidth link. We discuss our methods, results,(More)
—This work presents a hierarchical navigation architecture and cascade classifier for sample search and identification on a space exploration rover. A three tier navigation architecture and inverse Jacobian based robot arm controller are presented. The algorithms are implemented on AERO, the Autonomous Exploration Rover, participating in the NASA Sample(More)
BACKGROUND Many physicians believe that the most effective way to treat chronic urticaria is to take a nonsedating second-generation H1 -antihistamine in the morning and a sedating first-generation H1 -antihistamine, usually hydroxyzine, at night to enhance sleep. But is this belief well founded? OBJECTIVES To test this belief by comparing the(More)
We present the design evolution of robotic prosthetic hands at WPI over the last couple years. Following a user-centered design approach, we have identified a series of requirements that good prosthetic hand designs should have. We describe in detail the mechanical, electrical, and software subsystems of each hand, and the relative advantages and(More)
We present our preliminary results from the design process for developing the Worcester Polytechnic Institute's personal assistance robot, FRASIER, as an intelligent service robot for enabling active aging. The robot capabilities include vision-based object detection, tracking the user and help with carrying heavy items such as grocery bags or cafeteria(More)
We describe the process towards the design of a safe, reliable, and intuitive emergency treatment unit to facilitate a higher degree of safety and situational awareness for medical staff, leading to an increased level of patient care during an epidemic outbreak in an unprepared, underdeveloped, or disaster stricken area. We start with a human-centered(More)
— We propose a shared control architecture to enable the modeling of human-in-the-loop cyber physical systems (HiLCPS) in robotics applications. We identify challenges that currently hinder ideas and concepts from cross-domain applications to be shared among different implementation of HiLCPS. The presented architecture is developed with the intent to help(More)
