Optimizing Next-gen Machine Vision Platform To Enhance Automated Inspection

With machine vision’s development and growth in the Industry 4.0 environment, the higher computing performance becomes essential to acquire high resolution images at high speeds, and expanding FOV (field of view). The associated hardware must therefore significantly enhance reliability, to guarantee smooth operation of the production line. Read this white paper to know more about characteristics the next-gen machine vison platform need.

Lunar Regolith Simulant Sample Collection Mechanism for Remote Operation in a Thermal Vacuum Chamber

The Sample Capture Mechanism (SCM) is a remotely actuated, spring-driven mechanism designed to remotely capture and seal a 15-mL sample in less than 1 second. It was used to capture a 10-g sample of simulated regolith dispensed from a drill in a thermal vacuum chamber with a minimum temperature of –100 ºC. The sample crucible temperature is controllable from ambient temperature to 70 ºC.

Sonar Inspection Robot System

The system surveys interior volume, interrogates structure integrity, and displays real-time video and sonar.NASA’s Johnson Space Center innovators have designed a Robotic Inspection System that is capable of surveying deep sea structures such as oil platform storage cells/tanks and pipelines in order to determine the volume of material remaining inside, interrogate structure integrity, and display real-time video and sonar. This inspection device and method could significantly reduce the cost of inspecting, and in the future, provide sampling of the structure contents. The technology is an all-in-one inspection device that includes cameras, sonar, and motion-sensing instruments with hardware and software components. This NASA-developed technology is available for licensing.

Robonaut 2: Industrial Opportunities

The robot handles factory tasks that are ergonomically difficult, fatiguing, or unsafe for humans. Robonaut 2 lifts a 20-lb. weight with one hand, demonstrating the robot’s strength and endurance. Researchers at the NASA Johnson Space Center (JSC), in collaboration with General Motors (GM) 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 many applications, such as industrial environments. For example, in a traditional robotic assembly line, there are multiple specialized robots that are tooled for a small set of unique tasks. R2 provides an alternative way to implement automated assembly using extraordinary task flexibility, dexterity, and rapid interchangeability with human processes and tools. This can lower automation infrastructure costs and increase manufacturing flexibility. R2 can serve as an assistant or work independently. R2’s dexterity is a key feature in industrial environments, as the robot can handle factory work that is ergonomically difficult, fatiguing, or even unsafe.

Vessel Sealing Device for Robotic Devices

Invasive surgical procedures are essential for addressing various medical conditions. When possible, minimally invasive procedures are preferred, but these technologies are often limited in scope and complexity. These limitations are due in part to mobility restrictions from the use of rigid tools in small openings, and limited visual feedback. The currently available robotic systems are restricted by the use of access ports, and have limited sensory and mobility capabilities.
