Self-Learning Robot Hands Adapt to Grasp Objects

By connecting tactile sensors with intelligent software, the robot hands control their strength for a fine-touch grip that won’t damage delicate objects. (Bielefeld University)

A new grasp system with robotic hands works without previously knowing the characteristics of objects. The system, which learns by trial and error, was developed by researchers at Bielefeld University in Bielefeld, Germany. It features two hands that are based on human hands in terms of both shape and mobility. The robot brain for the hands must learn how everyday objects like pieces of fruit or tools can be distinguished based on their color or shape, as well as what matters when attempting to grasp the object; for example, a banana can be held, and a button can be pressed. The system learns to recognize such possibilities as characteristics, and constructs a model for interacting with and re-identifying the object.

Crawling Robot is Powered by Moisture

Researchers used flash-treated graphene oxide to create a crawler that moved when humidity was increased. Switching the humidity off and on several times induced the crawler to move 3.5 millimeters in 12 seconds, with no external energy supply. (Credit: Jilin University)

Using an off-the-shelf camera flash, researchers at Jilin University, China, turned an ordinary sheet of graphene oxide into a material that bends when exposed to moisture. They then used this material to make a spider-like crawler and claw robot that move in response to changing humidity, without the need for any external power.

Fast-Tracking ADAS and Autonomous Vehicle Development with Simulation

In Conjunction with SAE

Developing Advanced Driver Assistance Systems (ADAS) and autonomous vehicles is a challenge without precedent. Whole new engineering fields – such as artificial intelligence – need to be developed, yet time-to-market is short with intense competition. Estimates indicate that billions of miles of road testing will be necessary to ensure safety and reliability of ADAS and autonomous vehicles. This impossible task can only be accomplished with the help of engineering simulation. With simulation, thousands of driving scenarios and design parameters can be virtually tested with precision, speed, and cost economy.

Taking Manufacturing Control By Force

In today's data-driven world, there's no such thing as having too much information. From a product manufacturer's perspective, there are countless variables that can impact their production process. Among these variables are changes in force, where the slightest contact can make a major impact on efficiency and quality.

Autonomous Combustion-Powered Hopping Robot

Applications include military assistance, law enforcement, search and rescue, and homeland security.

Robots are conventionally made mobile by rolling on wheels; however, wheeled robots have limited ability to traverse large obstacles. Obstacles much taller than the robot's wheels can prevent passage, and obstacles with significant horizontal gaps, such as trenches, can also prevent passage. One solution is to use bigger wheels and a bigger wheelbase. Both of these require more drive power, so the entire robot must be larger. This can be prohibitive in applications with cost, size, space, or transportation constraints that limit the size of robot that can be used.

Omnidirectional Mobile Robot with Two Moving Parts

A spherical induction motor (SIM) eliminates the robot's mechanical drive system.

SIMbot is an updated version of the ballbot, an elegantly simple robot whose tall, thin body moves on top of a sphere slightly smaller than a bowling ball. SIMbot features a motor with just one moving part: the ball. The other active moving part of the robot is the body itself.

Interactive Robot Control System and Method of Use

Robonaut 2 can enter hazardous areas or tackle difficult terrain without endangering its human operator.

Researchers at NASA's Johnson Space Center (JSC), in collaboration with General Motors and Oceaneering, have designed a state-of-the-art, highly dexterous, humanoid robot: Robonaut 2 (R2). R2 is made up of multiple systems and sub-components: vision systems, image-recognition systems, sensors, control algorithms, and much more. R2's nearly 50 patented and patent-pending technologies have the potential to be game-changers in multiple industries. One of the most promising applications for the R2 technologies is in the area of hazardous environments. R2 has the capability to work in remote locations separate from the human controller. R2 can function autonomously, or it can be controlled by direct teleoperations.

Integrated High-Speed Torque Control System for a Robotic Joint

This highly dexterous humanoid robot is designed to handle complex and delicate operations.

Researchers at the NASA Johnson Space Center (JSC), in collaboration with General Motors and Oceaneering, have designed a state-of-the-art, highly dexterous, humanoid robot: Robonaut 2 (R2). R2's nearly 50 patented and patent-pending technologies have the potential to be game-changers in multiple industries, including logistics and distribution. Even though R2 is currently designed with only a mobile upper body, R2's ability to accomplish complex and delicate operations provides a higher level of sophistication not currently seen in the existing robotics field for logistics and distribution. In terms of handling inventory, R2's dexterity would allow it to handle a multitude of items, including delicate ones. R2 can safely work in close proximity to humans, making the robot suitable to work in complex environments such as distribution centers. R2 has the ability to operate equipment and machines designed for humans, like handheld power tools or inventory-scanning equipment. R2's design enables many useful applications in logistics and distribution.

Wearable Robotic System for Minimally Invasive Surgery

This tool supports and enhances the surgeon's performance in urology, cardiovascular, and orthopedic fields.

Researchers developed a wearable robotic system for minimally invasive surgery (also known as keyhole surgery) that will offer surgeons natural and dexterous movement, as well as the ability to sense, see, control, and safely navigate through the surgical environment. The need for better tools in robot-assisted minimally invasive surgery was identified to support and enhance the surgeon's performance in urology, cardiovascular, and orthopedic fields, and to expand the potential for this technology to more complex surgical procedures.
