3D-Printed Soft Robot ‘Walks’ on Any Terrain

Traditional robots often feature isolated mechanical joints. These discrete components limit a rover’s ability to traverse sand, stone, and other challenging environments.

A team at the University of California San Diego has demonstrated a more flexible option: a soft robot that lifts its legs over obstacles and operates on a variety of terrains. The 3D-printed quadrupedal technology may someday support search-and-rescue missions requiring intelligent navigation capabilities.

Interface Simplifies Remote Robot Operation

Georgia Institute of Technology researchers created a new interface to remotely control robots that is much simpler and more efficient than current techniques. The user simply points and clicks on an item, then chooses a grasp. The robot does the rest of the work.

The traditional interface for remotely operating robots employs a computer screen and mouse to independently control six degrees of freedom, turning three virtual rings and adjusting arrows to get the robot into position to grab items or perform a specific task. But for someone who isn’t an expert, the ring-and-arrow system is cumbersome and error-prone. It’s not ideal, for example, for older people trying to control assistive robots at home.

Origami-Inspired Robot Can Ride with a Rover

The Pop-Up Flat Folding Explorer Robot (PUFFER) that’s in development at NASA’s Jet Propulsion Laboratory in Pasadena, CA, was inspired by origami. It travels with a rover, and its lightweight design can flatten itself, tucking in its wheels and crawling into places rovers can’t fit.

Six-Legged Robots Move Faster with Bipod Gate

Researchers have discovered a faster and more efficient gait, never observed in nature, for six-legged robots walking on flat ground. Bio-inspired gaits, which are less efficient for robots, are used by real insects because they have adhesive pads to walk in three dimensions. (Credit: EPFL/Alain Herzog)

Researchers in Lausanne, Switzerland have determined that a bipod gait is the fastest and most efficient way for six-legged robots to move on flat ground, provided they don’t have the adhesive pads used by insects to climb walls and ceilings. This suggests designers of insect-inspired robots should make a break with the nature-inspired tripod-gait paradigm.

Tool Helps Design Soft Robots That Can Bend and Twist

Designing a soft robot to move organically — to bend like a finger or twist like a wrist — has always been a process of trial and error. Now, researchers from the Harvard John A. Paulson School of Engineering and Applied Sciences and the Wyss Institute for Biologically Inspired Engineering have developed a method to automatically design soft actuators based on the desired movement.

Prototype Capture System Simulates Asteroid Mission

A prototype of the robotic capture module system is tested with a mock asteroid boulder in its clutches at NASA’s Goddard Space Flight Center.

A robotic capture module system prototype was built to help NASA engineers understand the operations required to collect a multi-ton boulder from an asteroid’s surface. The hardware includes three space frame legs with foot pads, and two seven-degrees-of-freedom arms with microspine gripper “hands” to grasp onto the boulder.
