UNMANNED AUTONOMOUS VEHICLES
Safety is always a concern when using large autonomous vehicles. For autonomy to become commonplace in heavy industries such as mining, agriculture, and construction, operation requires a trusted navigation technology that excels in environments and conditions where GPS and vision sensors are lacking. Precision UWB ranging is the key aiding technology that will allow these large vehicles to safely and precisely navigate around people, other vehicles, and meet precision location requirements in all weather, lighting, dust, and multipath environments.
There are two significant types of GPS errors: ionosphere time of flight (TOF) errors and multipath errors. While dGPS and WAAS address the ionosphere issues, until now no one could address the multipath problem. GPS performance can be greatly enhanced using UWB ranging to correct the multipath errors.
Moving robots from the factory floor to warehouses, offices, and homes is all about cooperation. Precision indoor distance measurements from robot-to-robot, robot-to-anchor, and robot-to-person enable cooperation like never before. Seemingly simple autonomous behaviors, such as following or avoiding, mapping, hunting, and gathering will be efficiently performed.
The robot of the future is a group of small robots. Miniature robotic swarms will be enabled by this small UWB module that provides the robot radio trifecta: through-wall localization, wireless communications, and multi-static radar. Simultaneous localization and mapping (SLAM) becomes relatively easy when the resources of multiple sensors are combined with simultaneous precision separation distances.
Time Domain partner 5D Robotics uses our PulsON ranging radios as tags with their proprietary Behavior Engine (BE™) navigation software, allowing a robot to follow a human or other tagged object while avoiding collisions with other non-tagged objects.
Lockheed Martin's Convoy Active Safety Technology (CAST) merges LIDAR, GPS, and Time Domain's UWB ranging radios to enable driverless vehicles.
Chalmers University in Sweden uses Time Domain's P400 radios for collision avoidance in their Gulliver miniature vehicle testbed for smart highway research.
