At the beginning of the new millennia, wireless capsule endoscopy was introduced as a minimally invasive method of inspecting the digestive tract. The possibility of collecting images deep inside the human body just by swallowing a “pill” revolutionized the field of gastrointestinal endoscopy and sparked a brand-new field of research in robotics: medical capsule robots. These are self-contained robots that leverage extreme miniaturization to access and operate in environments that are out of reach for larger devices. In medicine, capsule robots can enter the human body through natural orifices or small incisions, and detect and cure life-threatening diseases in a non-invasive manner. This talk provides a perspective on how this field has evolved in the last ten years. We explore what was accomplished, what has failed, and what were the lessons learned. We also discuss enabling technologies, intelligent control, possible levels of computer assistance, and highlight future challenges in this ongoing Fantastic Voyage.

Bio: Pietro Valdastri (Senior Member, IEEE) received the master’s degree (Hons.) from the University of Pisa, in 2002, and the Ph.D. degree in biomedical engineering, Scuola Superiore Sant’Anna in 2006. He is a Professor and a Chair of Robotics and Autonomous Systems with the University of Leeds. His research interests include robotic surgery, robotic endoscopy, design of magnetic mechanisms, and medical capsule robots. He is a recipient of the Wolfson Research Merit Award from the Royal Society.

Robotic grasping and manipulation has historically been dominated by rigid grippers, force/form closure constraints, and extensive grasp trajectory planning. The advent of soft robotics offers new avenues to diverge from this paradigm by using strategic compliance to passively conform to grasped objects in the absence of active control, and with minimal chance of damage to the object or surrounding environment. However, while the reduced emphasis on sensing, planning, and control complexity simplifies grasping and manipulation tasks, precision and dexterity are often lost.

This talk will discuss efforts to increase the robustness of soft grasping and the dexterity of soft robotic manipulators, with particular emphasis on grasping tasks that are challenging for more traditional robot hands. This includes compliant objects, thin flexible sheets, and delicate organisms. Examples will be drawn from manipulation of everyday objects and field studies of deep sea sampling using soft end effectors

Bio: Robert Wood is the Charles River Professor of Engineering and Applied Sciences in the Harvard John A. Paulson School of Engineering and Applied Sciences and a National Geographic Explorer. Prof. Wood completed his M.S. and Ph.D. degrees in the Dept. of Electrical Engineering and Computer Sciences at the University of California, Berkeley. His current research interests include new micro- and meso-scale manufacturing techniques, bioinspired microrobots, biomedical microrobots, control of sensor-limited and computation-limited systems, active soft materials, wearable robots, and soft grasping and manipulation. He is the winner of multiple awards for his
work including the DARPA Young Faculty Award, NSF Career Award, ONR Young Investigator Award, Air Force Young Investigator Award, Technology Review’s TR35, and multiple best paper awards. In 2010 Wood received the Presidential Early Career Award for Scientists and Engineers from President Obama for his work in microrobotics. In 2012 he was selected for the Alan T. Waterman award, the National Science Foundation’s most prestigious early career award. In 2014 he was named one of National Geographic’s “Emerging Explorers”, and in 2018 he was an inaugural recipient of the Max Planck-Humboldt Medal. Wood’s group is also dedicated to STEM education by using novel robots to motivate young students to pursue careers in science and engineering.
