The technological issues and legal considerations associated with fully automated vehicles have prompted the automotive industry to focus more on supervised systems and advanced driver assistance systems (ADAS). Transportation departments worldwide are concerned with social, economic, or environmental objectives aimed at enhancing fuel and road network efficiency and quality of life. Recently, the...
The 2005 DARPA Grand Challenge, a 212-kilometer race through the Mojave Desert, showcased the state of the art in high-speed, autonomous navigation of trails and roads. To win the challenge, a team's robot had to complete the course faster than any other robot, and it had to do so within 10 hours. Carnegie Mellon University's Red Team developed two robots, which used a combination of autonomous and...
By combining smart sensors and traversability grids with a JAUS-based component and messaging architecture, DARPA Grand Challenge finalist team CIMAR quickly developed a robust autonomous ground vehicle (AGV), a custom-built off-road vehicle. Key components included six smart sensors for detecting environmental conditions and reporting a priori data, a smart arbiter for fusing data from multiple smart...
We perform an enormous number of functions while driving, and a computer trying to match a human driver must face all of them. Cornell University researchers offer an insider's perspective on the issues the DARPA Grand Challenge competitors faced in creating a humanlike driver - without the human. In preparing for the Grand Challenge, Cornell University's team divided the driving problem into three...
A new research system uses lasers to encrypt messages. A mirror reinjects part of the sending laser's initial signal back into the device's internal cavity, generating a new signal that chaotically fluctuates in amplitude. A modulator or coupler then injects a message into the new stream, which is all but unreadable if intercepted. The sending laser also transmits part of its initial signal into the...
As with early cinema, the serious and general game areas need to expand their collaboration with the technology community to advance games as media and further the technology and related computer science. Achieving this synergy will require additional formal collaborative frameworks with the technology communities. This synergy is perfectly natural - technology is used in all phases of modern videogame...
A new technique provides accurate, efficient ad detection for online TV rebroadcasts. As online television grows in popularity, providers are seeking cost-effective ways to replace original advertisements in rebroadcasts with new ads that are not only fresher but that can target individual viewers' interests and preferences. Alternatively, completely removing commercials might be desirable for subscribers...
The autonomous navigation systems (ANS), such as autonomous ground vehicles (AGVs), unmanned aerial vehicles (UAVs), and unmanned submersible vehicles (USVs), and modern vehicles with actuators, sensors, and computer control perform three basic functions: context gathering using sensors, processing, and action. Most researchers have put all three functions into the ANS or the robot itself to overcome...
