Scientists from Imperial College London have developed a 3D-printing Micro Aerial Vehicle (MAV) that mimics the way that swiftlets build their nests.The MAV is a quad-copter, with four blades that enable it to fly and hover. The vehicle, made from off-the-shelf components, carries in its underbelly two...

Thanks to a successful launch of the SpaceX-3 flight of the Falcon 9/Dragon capsule on Friday, April 18, the lower limbs for Robonaut 2 (R2) are aboard the International Space Station (ISS). Safely tucked inside the Dragon resupply vehicle, R2’s legs are to be attached by a station crew member to Robonaut’s torso...

University of Sheffield engineers have developed a way of making hundreds — or even thousands — of tiny robots cluster to carry out tasks. The robots do not require memory or processing power. Each robot uses just one sensor that indicates the presence of another nearby robot. Based on the sensor's...

Pepperl+Fuchs (Twinsburg, OH) has added flat-pack-style transmitter coupling devices to the WIS (short-range wireless inductive coupling system) product family. The new devices allow power and signal coupling to be transferred across an air gap of up to 20 mm. These wireless devices allow sensors to be connected to...

Two fundamental problems facing the development of a portable system to sustain life on extraterrestrial surfaces are (1) heat rejection and (2) rejection of metabolically produced CO2 to an environment with a ppCO2 of 0.4 to 0.9 kPa as is present on Mars. Portable life support systems...

A vehicle entering the atmosphere of a planet will do so at hypersonic speeds and will need to decelerate and maneuver through that atmosphere while protecting its payload from excessive heating. As a consequence, the vehicle shape must be designed to provide optimal aerodynamic lift and drag...
