Autonomous Aircraft To Help Fight Fires

Wildland fires are currently destroying many natural forested areas of the United States. These huge fires spread over natural terrain very rapidly and are difficult to control because they occur in remote areas, often burning everything in sight. Many people have lost their mountain homes due to wildland fires, and firefighters are having a difficult time controlling the fires from spreading further during the hot summer months. One weapon used against wildland firefighters is the heavy air tanker aircraft. Air tankers are designed to carry heavy payloads and when air tankers are used in wildland firefighting, they are equipped to carry enormous payloads of water or fire retardant to the location of the wildland fire and then drop their payload on the area of the fire as they fly overhead. Air tankers are invaluable in the fight against wildfires and are in high demand during fire season. Two companies, Thrush and Drone America, have teamed together to develop an autonomous air tanker that can be used to drop water and fire retardant on wildland fires while being piloted robotically. The autonomous air tanker is an enhancement of other drone-like aircraft currently in use by law enforcement and fire fighters. Current autonomous aircraft are used to monitor wildland fires from an aerial viewpoint, search for hot spots that may reignite, and photograph the spread of fires over time. Dropping a payload autonomously has significant benefits for emergency workers, however. Primarily, keeping pilots out of dangerous situations and flying over dangerous terrain is beneficial from a personnel standpoint. Also, autonomous aircraft have the benefit of being able to fly during the night time and navigate terrain successfully using onboard sensors. Since temperatures are usually lower at night, fires tend not to spread as quickly when the sun goes down, allowing autonomous air tankers to drop water and fire retardant on fires when they are less prone to spread. Plans for development are still under consideration, and teams from both companies are exploring other uses for autonomous aircraft as well. -taken from www.dronelife.com

Tesla Motors is Developing Driverless Cars

Tesla Motors’ autonomous vehicle system technology is progressing at a rapid rate towards being offered as an option on their vehicles. The autonomous system is being perfected to work in everyday driving situations to allow the vehicle’s driver to completely disengage from controlling the vehicle and allow the car to do all of the driving functions. Tesla has been developing their autonomous system for some time, and the system has undergone much iteration to get to the point at which it is capable of controlling a vehicle. Unfortunately, the current system, while very robust and dependable, is still prone to errors caused by circumstances that are unexpected under normal driving situations. Exact situations have not been shared, however speculations as to very quick moving obstacles in the path of travel, or even very small obstacles in the path of travel are thought to cause the autonomous system to fail. Driverless cars in general, including Tesla Motors, are under extreme scrutiny because of the significant dangers involved if a driverless car control system fails. Serious injury, property damage, or even death are all possible outcomes if a driverless car fails to operate properly. Tesla’s driverless autonomous vehicle system consists of a multitude of cameras and sensors that are supposedly capable of detecting objects around the vehicle as well as signage along the path of travel. Signs, such as stop signs or other warning indicators such as stop lights are identified by the driverless car and the car’s operation is changed appropriately to these signals. While the software behind controlling the vehicle’s sensors and cameras is currently still in development, the vehicles themselves are now being produced with the necessary hardware that will allow the cars to drive themselves in the near future. The software will be released as part of an update to the vehicle’s computer system and can be updated without significant maintenance to the vehicle.   Taken from Motor1
