Assembled from LEGO parts and programmed in just three days (and nights), these remarkable machines competed in two events that required them to navigate around obstacles -- in one case, to find a towering coffee pot, then push or pull it toward an image of a giant mug painted on the enclosure's floor; in the other, to escape from a room and reach an infrared beacon
Each time an ALI-SCOUT equipped car passes an infrared beacon, it transmits to the beacon stored data on its travel history since passing the last beacon.
When the car passes strategically located infrared beacons, typically attached to conventional traffic lights, the ALI-SCOUT unit receives approximately 8 kilobytes of data on area road networks and traffic, including route recommendations.
JCIMS is composed of combat identification panels (CIPs), thermal identification panels (TIPs), and Phoenix infrared beacons
. All three items have been around since the mid-90s and JCIMS remains the only platform marking capability within the US Army and our NATO Allies.
This goal can be met with the proposed localization system based on the infrared beacons. Infrared beacons cost is very low, but on the contrary to commonly used beacons the infrared beacons provide only the information about the bearing, not the ranging.
In the case of infrared beacons it is the measurement of relative angles between the robot and the beacons placed in known fixed positions;
Universal traffic management systems provide traffic information to drivers in real time using infrared beacons
that conduct two-way communications with individual vehicles.
"The robots have digital pheromones, digital compasses and infrared beacons
so they can learn the location of the recharging station and share this with the other bots.
Meanwhile, infrared beacons
mounted on the walls trigger a chimerical soundscape consisting of quotes from the poem as well as drum beats, a tolling bell and ocean noise.
were installed in the vehicles carrying athletes and officials.
Running from 1992 through 1997, FAST-TRAC uses infrared beacons
throughout the network to provide real-time traffic and route guidance information.
Optical sensors mounted on the head unit view panels of infrared beacons
