Traditional robots have been designed to perform a single task extremely efficiently. But when the item or the task changes, which is often the case with food, these traditional machines need to be reintegrated and reprogrammed
We have created electronic circuitry that is soft and stretchable and capable of spontaneously reforming electrical connections when the material is cut, torn, or punctured. It is made of microscopic droplets of liquid metal that are suspended in a soft silicone rubber.
Professor Cagdas Onal receives $500,000 grant for robots that combine soft and rigid properties; Robots can help in disaster zones or assist those physically challenged with everyday tasks
If robots are capable of rapidly adjusting their dampness, stiffing and dynamics, like octopi are, the added flexibility can make for more versatile robotics than ever.
The watery creation could lead to soft robots that mimic sea animals like the octopus, which can walk underwater and bump into things without damaging them.
If a robot is dealing with electronics, it needs to know whether its hand is sliding along a wire or pulling on it. If the robot needs to hold a medical instrument, it needs to know if the object is slipping or in a firm grip.
The mission of my lab is to discover new types of materials that will allow machines, robots, and electronics to be more compatible with our everyday environment.
Soft, Self-healing Devices Mimic Biological Muscles, Point to Next Generation of Human-like Robotics
The soft devices can perform a variety of tasks, including grasping delicate objects such as a raspberry and a raw egg, as well as lifting heavy objects. HASEL actuators exceed or match the strength, speed and efficiency of biological muscle.
Scott Schrage, University of Nebraska-Lincoln via Phys.org: The technique, which creates a stronger chemical bond between silicone and an unprecedented array of plastics, could greatly reduce the time, complexity and expense needed to produce the microfluidic devices.
James Vincent for The Verge: Each muscle consists of a sealed bag filled with air or fluid, containing a folding origami structure that functions as the skeleton.
Duncan Geere for Tech Radar: Now researchers from Universit© Paris-Saclay are attempting to bestow the same benefits onto robots. Adriana Tapus and her colleagues are aiming to develop a humanoid robot that's sensitive to tactile stimulation in the same way people are.
Penn's School of Engineering and Applied Science: Burka hopes to build up a database of one thousand surfaces to help coach robots on how to identify objects and also to know what they're made of and how best to handle them.
David Gianatasio for AdWeek: Unless you've been lost at sea, you've probably heard about the giant robotic squid that Old Spice deployed last weekend for a wacky, high-profile internet game on Twitch.
Matthew Humphries for PCMag: Catching a fish can be tough, even if you are just trying to net a goldfish in a small tank. That's because the fish spots the danger and makes a swim for it. But what if you didn't need a net because you're controlling an invisible grabbing robot? That's what Xuanhe Zhao, a professor of mechanical engineering at MIT succeeded in creating, but its applications go way beyond catching and releasing fish unharmed. The robot is constructed of a transparent hydrogel, which is strong and durable but mostly made of water. As the video below explains, each arm of the robot is constructed from 3D-printed hollow cubes of hydrogel, which are then linked together. By injecting water using a syringe it's possible to make the arms curl and uncurl quickly in a grabbing motion. Cont'd...
Written by AZoRobotics: Most robots achieve grasping and tactile sensing through motorized means, which can be excessively bulky and rigid. A Cornell group has devised a way for a soft robot to feel its surroundings internally, in much the same way humans do. A group led by Robert Shepherd, assistant professor of mechanical and aerospace engineering and principal investigator of Organic Robotics Lab, has published a paper describing how stretchable optical waveguides act as curvature, elongation and force sensors in a soft robotic hand. Doctoral student Huichan Zhao is lead author of “Optoelectronically Innervated Soft Prosthetic Hand via Stretchable Optical Waveguides,” which is featured in the debut edition of Science Robotics. The paper published Dec. 6; also contributing were doctoral students Kevin O’Brien and Shuo Li, both of Shepherd’s lab. Cont'd.. .

Servo2Go - CANopen Input Sinusoidal Brushless Servo Amplifiers establish a new benchmark in versatility
CANopen digital servo drives are designed to drive brushed and brushless servomotors in torque, velocity, or position mode and employs Space Vector Modulation (SVM), which results in higher bus voltage utilization and reduced heat dissipation compared to traditional PWM drives.
