Motion Control/​Automation

Two new fluidic actuator designs were developed to control fluid flow in ways that will ultimately result in improved system performance and fuel efficiency in to improve the aerodynamic performance of a variety of vehicles. These flow control actuators, often referred to as fluidic oscillators or sweeping jet...

In situ measurements of antenna patterns on rovers in a simulated terrain are difficult to make with conventional antenna range techniques. The desired pattern data covers a hemisphere above the antenna of interest, which is close to the ground. This is incompatible with traditional measurements that place...

In two new papers, MIT researchers demonstrate the promise of printable robotic components that, when heated, automatically fold into prescribed three-dimensional configurations.One paper describes a system that takes a digital specification of a 3-D shape — such as a computer-aided design,...

EPFL scientists from the Biorobotics Laboratory (BIOROB) have developed small robotic modules that can change their shape to create reconfigurable furniture. Like Lego bricks, Roombots pieces can be stacked upon each other to create various structures. Each 22 cm-long piece, which looks like...

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...
