In the realm of driverless vehicles, the automotive sector is generating the most buzz among the general public. Even with the recent advancements made in driverless car technology, there are still many bugs in the system that must be worked out before cars drive on public roadways, free from human intervention. While road travel may need to be worked out, vehicles operated privately or off the roadways face their own challenges. Vehicles that are operated off of public roadways, sometimes referred to as off-highway vehicles, are used in many industries. Some of the biggest industries that utilize off-highway driverless technology are the mining industry and the agricultural industry. Vehicles in these industries benefit greatly from being driverless, and these industries have taken advantage of driverless technology for years.
Off-highway vehicles that are outfitted with driverless technology face a different set of challenges than those faced by vehicles operated on public roadways. Some of the challenges are easy to overcome, and some are not. For example, mining equipment must remain in a relatively well-defined area while operating. The area, or mine, is an area that can be properly defined by the driverless vehicle, providing easy navigation and reduction of unknown obstacles. Second, dynamic obstacles, such as humans or other car drivers, are minimized resulting in a decrease to unknown variables. Other challenges pose unique risks to the driverless off-highway vehicle. For example, many off-highway vehicles operate in a very specialized manner, such as agricultural tilling machines. While tilling machines may operate in a defined path, knowing the conditions necessary to properly till a field are much different than the conditions required for roadway travel. Thus, the controls and operations of such off-highway vehicles are more customized and taylor-made for the particular sector of industry. As many experts in these industries will relate, there is not a “one-size fits all” solution to off-highway driverless vehicles.

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.

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.
