Robot leads senior fitness classes, corrects participant form

Robocoach uses motion-sensor technology to coach seniors during exercise classes. Created by Ngee Ann Polytechnic student Lim Pei Xuan, the robot has blue eyes and two teeth, and mimics human movements, Voices are recognized, including instructions to start the session. In large group workouts, the pace is slowed, to ensure that everyone can keep up.   Robocoach […]

Robot sensor reads facial expressions to determine emotions

Sungkyunkwan University‘s Nae-Eung Lee has created a stretchable, transparent sensor that helps robots read facial expressions.  It senses smiling, frowning, brow-furrowing and eye-rolling.  The robot then detects movements, including slight changes in gaze, to determine whether people are laughing or crying, and where they are looking. The ultra-sensitive, wearable sensor layers a carbon nanotube film on two types of […]

Robot helps build social skills in autistic kids

Milo by RoboKind is a humanoid robot designed to engage and build social skills in children with autism.  It is used with  the company’s Robots4Autism curriculum which includes conversation, social situation, and emotional understanding modules. Milo is 2 feet tall, with a childlike voice and facial features.  Its arms move and facial expression change. Sensors gauge eye contact, which is […]

Tiny robotic gripper for cancer diagnostics, remote surgery

Johns Hopkins professor David Gracias has created a tiny, flexible, microscopic, robotic,  hand-like hydrogel gripper that could help doctors perform remotely guided surgical procedures and biopsies.    He believes that the materials could also, in the future,  deliver therapeutic drugs to difficult to reach places. The hydrogel can swell in response to changes in temperature, acidity or light, providing […]

BCI enabled 10-D prosthetic arm control

Jennifer Collinger and University of Pittsburgh colleagues have enabled a prosthetic arm wearer to reach, grasp, and place a variety of objects with 10-D control for the first time. The trial participant had electrode grids with 96 contact points surgically implanted in her brain in 2012.  This allowed 3-D control of her arm. Each electrode point picked up signals […]

Applied robot control theory for more natural prosthetic leg movement

Prosthetics are lighter and more flexible than in the past, but fail to mimic human muscle power. Powered prosthesis motors generate force, but cannot respond with stability to disturbances or changing terrain. Robert Gregg and colleagues at the University of Texas have applied robot control theory to allow powered prosthetics to dynamically respond to a wearer’s environment. […]

NIH “Bionic Man” with 14 sensor and brain controlled functions

The National Institute of Biomedical Imaging and Bioengineering recently launched the “NIBIB Bionic Man,” an interactive Web tool detailing 14 sensor based technologies they are supporting.  They include: 1. A robotic leg prosthesis that senses a person’s next move and provides powered assistance to achieve a more natural gate. 2. A light sensitive biogel and […]

MIT’s running, jumping cheetah robot, now wireless

MIT‘s Biomimetic Robotics Lab has  unveiled a robotic cheetah that jumps hurdles and sprints at 10 mph, mimicking the natural bounding motions of a cheetah.   The robot can leap across uneven terrain while still maintaining a steady speed, and cleared a 33 centimeter foam hurdle.  The research team believes that the robotic cheetah could eventually reach speeds of […]

Context sensitive robot understands casual language

Cornell professor Ashutosh Saxenam is developing a context sensitive robot that is able to understand natural language commands, from different speakers, in colloquial English.  The goal is to help robots account for missing information when receiving instructions and adapt to their environment. Tell Me Dave is equipped with a 3D camera for viewing its surroundings.  Machine learning has enabled […]
