The Department of Defense has put out a call: design a pack of robots. A so-called Multi-Robot Pursuit System would be used to "search for and detect a non-cooperative human subject." Each robot has to weigh 100 kilograms or less, act autonomously (with a human squad leader), negotiate obstacles, and provide immediate feedback. The robots would report back to a human operator, and defer to that human when the robot AI determines that a "difficult decision" is required. The first phase of development is to create the sensors for detecting humans and to conduct feasibility experiments. Then comes the building of a prototype with fully functional sensors. At that point, a third phase would try to establish whether a pack of such robots -- about three to five in number -- could realistically be used for missions involving, according to the proposal, "search and rescue, fire-fighting, reconnaissance, and automated biological, chemical, and radiation sensing with mobile platforms."

Honda Unveils Robot That Helps You Walk, Funny-looking bipedal machine that supports weight, regulates stride actually very useful in rapidly aging Japan. Imagine a bicycle seat connected by mechanical frames to a pair of shoes for an idea of how the new wearable assisted-walking gadget from Honda works. The experimental device, unveiled Friday, is designed to support bodyweight, reduce stress on the knees and help people get up steps and stay in crouching positions.
