Thanks, Al, for that input. I would think that both problems must be not too difficult to fix, and that the fixes would be primarily a matter of tweaking sensors.
I'm sure that work is ongoing given the success of the Kinect. Heard those limitations from one of the suppliers developing robotic tools to use with the Kinect.
Al, thanks for those additional details on the Kinect sensor's limitations. The fact that it doesn't detect objects less than two feet away should not be a deterrence to its use in checking out a new environment for military tasks, such as in advance of first responders. But I'm surprised that it doesn't work well in sunlight--that seems like a major limitation for these applications, and for helping the elderly or disabled, both of which were two applications the MIT team mentions and which occur at least partly in sunlight. I would not be surprised if this research team is working on methods for overcoming that problem, also.
Ann, Used as a tool to aid in developing mobile robots, the Kinect sensor provides a unique type of feedback which can be used in conjunction with flexible I/O, software algorithms and real-time controllers to quickly and easily prototype, test and deploy robotic applications. The development tools already available make it great for prototyping. But while the Kinect is useful for common robot tasks such as obstacle avoidance, like most sensors it also has limitations. For example, the Kinect cannot detect obstacles that are closer than two feet and does not work well in the sunlight. Still great technology at a mind boggling cost.
Al, I agree that obstacle-avoidance and mapmaking software is a big deal. Specifically, the map-making/obstacle avoidance algorithms based on Simultaneous Localization and Mapping (SLAM) techniques mentioned here, which may also be what's behind the tiny swarming robots' mapmaking ability:
One additional area of software innovation for mobile robots is algorithms for obstacle avoidance. Especially in systems where the mobile robot will encounter humans, such as the tire warehousing application, where the robot is "delivering" a completed tire to a storage/retrieval system, the mobile robot can encounter workers during that delivery process. The software to control those interactions are interesting and also critical to the success of the application.
Ann, The key technology with the mobile robots I've seen is software enhancements and intelligent algorithms. Enhancements in vision systems, for example, provides the mechanism to visualize and ultimately "map" the factory environment but in the end the most difficult task is the mass of intelligent software required. It ranges from becoming an expert system (gathering information to make more informed decisions) to advanced databases for storing information. Lots of software
Beth, I agree, I've also seen mentions of the Kinect motion sensor device all over. Combined with a tiny camera and software, it's revolutionizing input devices and user interfaces in a lot of apps.
ChasChas, that's an interesting question you pose. But some of these newer robots will be functioning autonomously, like this one, i.e., not under direct human control. So if these are designed as soldiers, not as merely explorers, the ethical situation changes somewhat.
was my first encounter with what are called autonomous robots, and the one in this story is my second. Both made me wonder where else that idea is being used, and what different technologies make them possible, in particular, the navigation and map-making abilities. The industrial environment is certainly an obvious choice.
By refining topologies and using new fluid technology, Moog's new peak sine drive controller increases available power without increasing controller volume.
Lantronix Inc. has expanded its line of controllers for sensor networks with the release of a rugged controller that improves management of automation systems used in a number of industries, including manufacturing, oil and gas, and chemicals.
Inspired by the hooks a parasitic worm uses to penetrate its host's intestines, the Karp Lab has invented a flexible adhesive patch covered with microneedles that adheres well to wet, soft tissues, but doesn't cause damage when removed.

A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
