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.

Dike Inspection Robot is Energy-Autonomous

The robot's drive train, including the dual-hemisphere system. (Image: University of Twente) Inspecting the condition of dikes and other sea defense structures is typically a task for robots, working in a team and in a highly autonomous way. But if they move around across the dikes, perform tests, and communicate the results for six hours a day, they use a lot of energy.

System Harvests Energy from Automotive Shock Absorbers

The energy harvesting device focuses on the car’s suspension – specifically, the shock absorbers. Boosting the fuel efficiency of motor vehicles by “harvesting” the energy generated by their shock absorbers and feeding it back into batteries or electrical systems such as air conditioning has become a major goal in automotive engineering. A University of Huddersfield (UK) researcher has designed a new system and built a prototype that is ready for real-world testing.

Laser-Driven Light Source

Energetiq Technology (Woburn, MA) has introduced its 5th generation, ultra-bright, Laser-Driven Light Source (LDLS™), the EQ-77. The EQ-77 offers higher radiance and irradiance from a truly broadband white light source. The EQ-77 features a compact lamp house, with clean construction that ensures long life and ultimate stability. With a wavelength range from 170nm in the deep ultraviolet to >2µm in the near infrared, and a choice of dual-beam output or a single-beam output with retro-reflector, the EQ-77 is flexible for a broad variety of applications.To learn more, click here

Diffuse Reflectance Probe

The Ocean Optics (Dunedin, FL) Diffuse Reflectance Probe (DR-Probe) measures 45° diffuse reflectance, enhancing UV-Vis and NIR spectroscopy results. The DR-Probe integrates a light source and collection optics into one unit. With the probe’s collection optics fixed in place relative to the light source, the measurement geometry is constant. An included standoff accessory ensures a consistent 40 mm focal length between the probe and the sample. The DR-Probe has rugged, all-metal construction for durability, and its 6W tungsten halogen bulb has a 10,000-hour lifetime.To learn more, click here

CoaXPress Frame Grabber

Responding to the need to create a cost-effective, high-speed interface to fully leverage CXP cameras, BitFlow (Woburn, MA) has introduced the Aon-CXP single link CoaXPress frame grabber. The Aon is powerful enough to support camera speeds up to 6.25 Gigabits/second, which is almost twice as fast as USB3 and over six times the speed of current offerings of GigE Vision. While capturing video at those speeds, it is simultaneously sending control commands, triggers and up to 13 W of power over a single piece of 75 Ohm coaxial cable.To learn more, click here
