A team at the University of Japan have developed a camera system for tracking fast moving objects automatically and accurately without motion prediction. The example video shown on their website demonstrates the camera tracking a ping pong game. Even a high-speed object like a bouncing pingpong ball in play can be tracked at the center due to a high-speed optical gaze controller Saccade Mirror and a 1000-fps high-speed vision. The Saccade Mirror controls a camera's gazing direction not by moving the camera itself but by rotating two-axis small galvanometer mirrors. It takes no more than 3.5 ms even if it controls the gaze by 60 deg, the widest angle, for both pan and tilt. The newest prototype system accesses a Full HD image quality for an actual broadcasting service.

The International Association for Robots in Architecture has released an update to it's Grasshopper plugin: KUKA:prc. Grasshopper is visual programming language built on top of the Rhino3D modeler. Grasshopper can be used to generate complex 3d structures procedurally by chaining together operations using its node-based IDE. KUKA:prc enables you to program industrial robots directly out of the parametric modeling environment, including a full kinematic simulation of the robot. The generated files can be executed at the KUKA robot, without requiring any additional software. The new release includes several preset profiles existing KUKA robots and is free (at least for the time being) to download and test here .
An old video recently surfaced demonstrating Pantomation, a tracking system built in 1977. The system was built with some variation of the PDP and could track body movement by isolating objects held by performers and was used to drive music or live performances. Cool early stuff.

The MPU-9150 is a System in Package (SiP) that combines two chips: the MPU-6050, which contains a 3-axis gyroscope, 3-axis accelerometer, and an onboard Digital Motion Processor™ (DMP™) capable of processing complex 9-axis MotionFusion algorithms; and the AK8975, a 3-axis digital compass. The part’s integrated 9-axis MotionFusion algorithms access all internal sensors to gather a full set of sensor data. For precision tracking of both fast and slow motions, the parts feature a user-programmable gyro full-scale range of ±250, ±500, ±1000, and ±2000°/sec (dps), a user-programmable accelerometer full-scale range of ±2g, ±4g, ±8g, and ±16g, and compass with a full scale range of ±1200µT. Designworld has a video from InvenSense's CES 2012 booth demonstrating the MPU-9150. The DIYDrones post has additional info and comments. Official product site.

IEEE Spectrum has info about a new autonomous lawnmower from the German company Bosch. Seems the only official info available at the moment is a Swedish press release but it appears the mower communicates with its docking station (and maybe GPS) allowing the unit to cut areas in ordered parallel lines rather than the chaotic back and forth paths you see from other sensor based robotic lawnmowers or vacuums. You will still have to install wire around the perimeter so the robot stay on the grass. The battery lasts 20 minutes per charge and resumes where it left of after a 90 minute charge.
The Fluid Mechanics Laboratory and the Swartz Lab at Brown University are in development of a biological inspired bat robot platform that aims to reproduce the amazing maneuverability of these flying mammals. Bats exhibit extraordinary flight capabilities that arise by virtue of a variety of unique mechanical features. These flying mammals have developed powerful muscles that provide the folding and extension of their wing-membrane during flight (morphing). The maneuverability is achieved by reproducing the flapping and morphing capabilities of their wing-skeleton structure. This structure is composed by several joints and a membrane that generates the required lift forces to fly. Each wing has 4 degrees of freedom: the shoulder has two, the elbow joint is actuated by Migamotors SMA-muscles, and the wrist is an under-actuated joint that moves as a function of the elbow. The robot morphology is alike in proportion compared to the biological counterpart (half the size): total wingspan: 50cm, humerus length: 5.5cm, and radius: 7cm. The total weight of the skeleton is 34g (including both wings). The morphing actuation mechanism attached to the humerus bone is based on smart muscles that provide elbow rotation. More info can be found on their research site here .
ROSCon 2012 was held in St. Paul, Minnesota over the weekend. Willow Garage was showing off a prototype refresh of the TurtleBot. The biggest change is that the iRobot Create bases are being replaced by a new base designed by the South Korean company Yujin Robot. They are calling the new base Kobuki and it has a number of upgrades from the Create base. Changes include an odometry system, integrated gyroscope, large batteries, and access to all the hardware through a panel at the back of the base. Kobuki will also have the ability to use a self-charging dock that can feed power to both the base and the attached laptop make 24/7 operation possible. The Kobuki official site.
Honda Motor Co. unveiled the new UNI-CUB personal mobility device. UNI-CUB features Honda's proprietary balance control technology and the world's first omni-directional driving wheel system (Honda Omni Traction Drive System). The technology thrown into the making of UNI-CUB comes from Honda's research into the ASIMO robot. The UNI-CUB allows the rider to control speed, move in any direction, turn and stop, all simply by shifting his or her weight. Since the rider can freely move forward, backward, side-to-side and diagonally. Starting in June 2012, Honda will jointly conduct demonstration testing of UNI-CUB with Japan's National Museum of Emerging Science and Innovation.
HyQ is a fully torque-controlled Hydraulically actuated Quadruped robot (pronounced [hai-kju:]) developed in the Department of Advanced Robotics at the IIT. HyQ is designed to move over rough terrain and perform highly dynamic tasks such as jumping and running with different gaits (up to 3-4m/s). To achieve the required high joint speeds and torques, a combination of hydraulic cylinders and electric motors are actuating the robot’s 12 active joints.
Travis Deyle at Hizook has some interesting info about Redwood Robotics, a Silicon Valley startup with backing from Willow Garage, Meka Robotics and SRI. The company has been in stealth mode for the past year but yesterday at an event in Menlo Park they announced the first real statement about their plans for the company. At the event Aaron Edsinger, who is CEO of Meka Robotics, said the goal of the new company would be: "To enable the personal and service robot markets through a new generation of robot arms that are simple to program, inexpensive, and safe to operate alongside people." Sounds like a smart plan. Be sure to read Deyle's full post over at Hizook.
The Artisans Asylum in Boston Massachusetts s a non-profit community craft studio. In their next robotics class their goals are fairly simple: build a car-sized two-person hexapod robot and ride it. What makes their plans different from the scribbling of every 12 year old who just found Japanese animation is that the guys teaching the class have worked on projects real projects like Boston Dynamics PETMAN, AlphaDog and BigDog. Hizook does a good job of summarizing what Artisans Asylum is and Stompy. The project is still in the conceptual stages but the team has a blog with some of the tests and presentations they've done so far.
The ExoHand from Festo is an exoskeleton that can be worn like a glove. The fingers can be actively moved and their strength amplified; the operator's hand movements are registered and transmitted to the robotic hand in real time. The fingers can be actively moved and their strength amplified; the operator’s hand movements are registered and transmitted to the robotic hand in real time. The objectives are to enhance the strength and endurance of the human hand, to extend humans’ scope of action and to secure them an independent lifestyle even at an advanced age. .
