Rapid Forest Triage by Sub-Canopy Micro Air Vehicles

Applications include rapid assessment of biomass for commercial forestry and carbon offsets. NASA’s Jet Propulsion Laboratory, Pasadena, California Today, tree distribution maps can only be generated manually in a very time-consuming process, and real-time microclimate mapping of a large 3D volume under tree canopy is not possible. A prototype small quadrotor unmanned aerial vehicle (UAV) system was developed that is able to maneuver in cluttered environments like forests, and under tree canopy to map tree distributions from 3D point clouds gathered from an onboard stereo vision system. The UAV uses a small onboard sensor board to record micro-climate parameters during flight.

Insertable, Miniature, In-Vivo Surgical Robot with Embedded Control

Lyndon B. Johnson Space Center, Houston, Texas This innovation is a miniature, in-vivo surgical robot that is able to be inserted into the peritoneal cavity under insufflation. It is designed to perform Laparoendoscopic Single-Site Surgery (LESS). This robotic device is capable of direct visualization of the surgical procedure, and manual or autonomous repositioning within the abdominal cavity.

Executive Perspectives: Robotics

CHETAN KAPOOR Senior Director of Technology Innovation Yaskawa America, Motoman Robotics Division Miamisburg, OH www.motoman.com Programmable machines are increasingly joining the ranks of the workforce. Ironically, these machines have been around for 40 years. I call them Generation Bot. Since the 1970s, industry and consumers have seen robots successfully perform highly repetitive tasks where the value proposition was improving the rate of production, controlling or reducing labor costs, ensuring quality, and addressing ergonomic concerns.

Executive Perspectives: Robotics

JIM LAWTON Chief Product and Marketing Officer Rethink Robotics Boston, MA www.rethinkrobotics.com In 1961, Unimate — the first large-scale industrial robot — transformed the assembly lines at General Motors. Reading the headlines today, it seems we’re on the precipice of a new era where robots will do just about anything that humans can. These machines will drive our cars, report the news, perform surgery, and fold our laundry — and it all comes across as though the innovation just started at the turn of the century.

Soft Robot Fingers Collect Delicate Coral

Most deep sea robotic manipulators are constructed from hard materials that are not geared to collect fragile coral. Researchers at the Wyss Institute, Harvard Paulson School, and City University of New York have developed a soft robotic gripper that can safely handle delicate specimens, including biological specimens on deep reefs.

Contact State Estimation for Multi-Finger Robot Hands Using Particle Filters

This method identifies the location, orientation, and shape of an object touched by a robot hand. Lyndon B. Johnson Space Center, Houston, Texas A method, using a particle filter, has been created for identifying the location, orientation, and shape of an object that a robot hand touches. An appropriate motion model has been defined that characterizes the motion of the robot hand as it moves relative to an object. The measurement model also estimates the likelihood of an observation of contact position, velocity, and tactile sensor information given handobject states, and is approximated analytically based on a geometric model, or on a corpus of training data. In either case, the measurement model distribution is encoded as a Gaussian, or using radial basis functions.
