Researchers develop bionic arm that restores natural behaviors in patients with upper limb amputations

Cleveland Clinic researchers have engineered a first-of-its-kind bionic arm for patients with upper-limb amputations that allows wearers to think, behave and function like a person without an amputation, according to new findings published in Science Robotics.

DefGraspSim: A pipeline to evaluate robotic grasping of 3D deformable objects

Over the past few decades, roboticists and computer scientists have developed robots that can grasp and manipulate various objects in their surroundings. Most of these robots are primarily trained to grasp rigid objects or objects with specific shapes.

A policy to enable the use of general-purpose manipulators in high-speed robot air hockey

To perform well on highly dynamic tasks, robots should be able to move quickly and be highly reactive. As robots typically have physical constraints and hardware limitations, computer scientists should also develop planners and trajectory optimization techniques that will enable them to perform rapid movements.

An omnidirectional octopus-like robot arm that can stretch, bend and twist without a motor

A combined team of researchers from The Ohio State University and the Georgia Institute of Technology has developed a robot arm that moves like an octopus arm without the need for a motor. In their paper published in Proceedings of the National Academy of Sciences, the group describes their robot arm, which moves in response to changes in a magnetic field around it.

Robot mimics the powerful punch of the mantis shrimp

Mantis shrimp pack the strongest punch of any creature in the animal kingdom. Their club-like appendages accelerate faster than a bullet out of a gun and just one strike can knock the arm off a crab or break through a snail shell. These small but mighty crustaceans have been known to take on octopus and win.

Combined approach finds best direct trajectory for robot path generation

When a robot needs to move across a room, there are several paths, each with curves and multiple potential starting and ending points. How does it decide the most efficient, cost-effective approach? A collaborative team of researchers in the United States may have the answer. They developed a method to determine the optimal solution for this kind of general control problem, which could apply to the decision making needed to move from point A to point B to more complex automated, robotic navigation. They published their results in the August 2021 Issue, IEEE/CAA Journal of Automatica Sinica.

First steerable catheter developed for brain surgery

A team of engineers and physicians has developed a steerable catheter that for the first time will give neurosurgeons the ability to steer the device in any direction they want while navigating the brain's arteries and blood vessels. The device was inspired by nature, specifically insect legs and flagella—tail-like structures that allow microscopic organisms such as bacteria to swim.

Magnets could offer better control of prosthetic limbs

For people with amputation who have prosthetic limbs, one of the greatest challenges is controlling the prosthesis so that it moves the same way a natural limb would. Most prosthetic limbs are controlled using electromyography, a way of recording electrical activity from the muscles, but this approach provides only limited control of the prosthesis.
