I say ironically because HAL is the Artificial Intelligence villain of science fiction. But the exoskeleton HAL is in fact far friendlier. It has been designed to support and expand the physical capabilities of its users, particularly people with physical disabilities.

UPDATE 04/03/2014:

In this video update, we show that a quadrocopter can be safely piloted by hand after a motor fails, without the aid of a motion capture system. This follows our previous video, where we demonstrated how a complete propeller failure can be automatically detected, and that a quadrocopter can still maintain stable flight despite the complete loss of a propeller.

Tjin Van Der Zant helped found “Robocup at Home” in 2006, and since then the organization has spread to include a number of new locations everywhere from Brazil to Thailand. As a professor at the University of Groningen in the Cognitive Robotics Lab, and founder of a Robotics startup and machine learning startup – he’s pretty “involved” when it comes to robots – and it made me eager to pick his brain about the future of home robotics.

RoboEarth - mapping in the cloud

UPDATE: New video of a collaborative, cloud-based mapping experiment. Mapping is essential for mobile robots and a cornerstone of many more robotics applications that require a robot to interact with its physical environment. It is widely considered the most difficult perceptual problem in robotics, both from an algorithmic but also from a computational perspective. Mapping essentially requires solving a huge optimization problem over a large amount of images and their extracted features. This requires beefy computers and high-end graphics cards – resulting in power-hungry and expensive robots.

Update: New video of final robot! My colleagues at the Institute for Dynamic Systems and Control at ETH Zurich have created a small robotic cube that can autonomously jump up and balance on any one of its corners.

The DelFly Explorer is the first flapping wing Micro Air Vehicle (MAV) that is able to fly with complete autonomy in unknown environments. Weighing just 20 grams and with a wingspan of 28cm, it is equipped with an onboard stereo vision system. The DelFly Explorer can perform an autonomous take-off, keep its height, and avoid obstacles for as long as its battery lasts (~9 minutes). All sensing and processing is performed on board, so no human or offboard computer is in the loop.

Gimball is a flying robot that survives collisions. It weighs just 370g for 34cm in diameter. Photo credit: A. Herzog, EPFL.

Generally, flying robots are programmed to avoid obstacles, which is far from easy in cluttered environments. At the Laboratory of Intelligent Systems, we think that flying robots should be able to physically interact with their surroundings. Take insects: they often collide with obstacles and continue flying afterwards. We thus designed GimBall, a flying robot that can collide with objects seamlessly. Thanks to a passively rotating spherical cage, it remains stable even after taking hits from all sides. This approach enables GimBall to fly in the most difficult places without complex sensors.

Kawasaki Heavy Industries has developed the world’s first all stainless steel robot with seven degrees of freedom.

It will be used in the drug discovery and pharmaceutical fields to automate experiments which use dangerous chemicals.

Due to its stainless steel body, it can be sterilized using Hydrogen Peroxide gas, for work in sterile environments.

This remote medical care robot for use in emergency situations, is under development by a research group at Waseda University, led by Dr. Hiroyasu Iwata.

“If a person receives an impact in an accident, there is a possibility that they could have internal bleeding. In emergency rooms, there’s a diagnostic method called FAST, using ultrasound imaging to check for internal bleeding. But that can’t be done until the patient reaches the hospital. So our idea is that this robot can be put on the patient in an ambulance, and while on the way to the hospital, it can be controlled by a doctor in a remote location. As there is ultrasound probe attached, this robot can be used to check for internal bleeding.”

Unlike larger robots, microrobots for applications in the body are too small to carry batteries and motors. To address this challenge, we power and control robots made of magnetic materials using external magnetic fields. Developed at ETH Zurich’s  Multi-Scale Robotics Lab (MSRL), the OctoMag is a magnetic manipulation system that uses electromagnetic coils to wirelessly guide microrobots for ophthalmic surgery.

This camera system can track very fast moving objects, keeping them in the center of the screen at all times. Currently under development by the Ishikawa Oku Lab. at the University of Tokyo, this latest version captures Full HD video and can be used outdoors.

“Ordinarily, to change the direction a camera faces, you move the camera mechanically. But in this system, it’s not the camera that moves, it’s the mirrors. This makes it possible to change where you’re looking really quickly. In this demonstration, we’re tracking a table tennis ball. The ball moves extremely fast, but this system can keep compensating for the ball’s motion, so the ball stays in the middle of the image.”

Fujitsu has developed technology which can measure a person’s pulse in real time by analyzing video of their face.

“As blood circulates through the body, the amount of light absorbed by the face varies, depending on how much blood there is in it. The first point about this technology is, it identifies minute changes in light intensity on the face, and converts them to a pulse. Also, it accurately detects people’s movements, to distinguish noise. Consequently, it can make a measurement in as little as five seconds.”

How do you like to go up in a swing,
Up in the air so blue?
Oh, I do think it the pleasantest thing
Ever a child can do!
