During the CES 2019 show in Las Vegas earlier this year, there were many different drone manufacturers displaying the newest technologies used in air travel. Drones are taking over many realms that were otherwise thought as unachievable. Amazon has been working with drones for years in order to develop a new method for shipment deliveries. Their work towards this goal has been met with much criticism due to the obvious obstacles that must be overcome, however the progress that Amazon has made has spurred other concepts for new technology. During the CES show, for example, there were manufacturers who were displaying autonomous taxi drones that are capable of carrying human passengers for relatively short distances. These drone taxis, such as the Bell Nexus, use vertical take off and landing technology and a high payload capacity to carry 5 passengers up to 150 miles in distance. While Bell originally planned for the Nexus to be flown by a pilot, new drone technology has made it possible to make the Nexus completely autonomous and capable of flying itself from one point to the next. The idea of aerial autonomous taxi services has caught the attention of ride share companies such as Uber. In fact, Uber has partnered with Bell to help promote the Nexus as a new vehicle for passenger transportation. While Uber has high hopes for the futuristic autonomous taxi drone technology, there are many obvious safety and legal concerns involved with developing this technology. For one, drones in general have become very well regulated by the Federal Aviation Administration because they are becoming so prevalent. Improper drone flights that pose safety hazards to manned aircraft are also becoming more prevalent and the reputation for drones in general is not a positive one. Because of the increase in regulations, new concepts for autonomous drones will require strict testing to ensure that passengers on drone taxis as well as other manned aircraft remain safe during flight. It will likely be quite a while before this technology sees commercial operation. However, regardless of the obstacles, companies like Bell and Uber are very optimistic that the future of passenger transportation will be accomplished by unmanned autonomous vehicles.

The United States Air Force recently tested a new autonomous
flight system for use on small unmanned aerial vehicles, or drones. The system
was developed in conjunction with John’s Hopkins University. The unmanned
aerial vehicle system is designed to communicate flight information, such as
position, speed, and aircraft orientation back to an artificial intelligence
system that is designed to control the aircraft if it has violated
predetermined course information. The system, called the Testing of Autonomy in
Complex Environments, or TACE for short, can monitor autopilot software and
re-direct the unmanned aerial vehicle back to a safety area if it approaches a
virtual border. This functionality could be useful for many purposes, and one
main commercial use would be to prohibit drone flight around manned aircraft or
within certain restricted airspace. Flights of unmanned aerial vehicles in
prohibited areas is a common occurrence among amateur pilots and poses a
significant safety risk to manned aircraft. A system to virtually block
unmanned aerial vehicle flight from prohibited areas would be a step towards
safer air travel.
The Testing of Autonomy in Complex Environments system also fulfills the function of an simulated entity for use with live aircraft flight. In other words, the Testing of Autonomy in Complex Environments system will be able to fly along other aircraft as a “virtual wingman” with simulated sensors, to enhance constructive flight training and during combat. An autonomous flying system could be a significant asset to the warfighter. The Testing of Autonomy in Complex Environments development comes as a part of the 2018 National Defense Strategy to develop, test, and implement autonomous and AI systems for use by the Air Force. The Air Force’s Combined Test Force with John’s Hopkins University plans to conduct more autonomous flight testing of the Testing of Autonomy in Complex Environments system and will test on unmanned aerial vehicles that can fly up to 250 miles per hour during the summer of 2019.

Batteries are destined to change the future in many ways. One of those ways is by completely disrupting the fossil fuels industry by replacing gasoline powered vehicle with electric vehicles. What is one of the key limiting factors on battery production? Cost. The cost of battery production has dropped significantly in recent years, but it is still expensive to produce batteries. Not to mention, the energy contained in batteries is still substantially less than that of gasoline or other fossil fuels. Therefore, significant obstacles must still be overcome. Even with these obstacles, batteries will someday replace the need for fossil fuels in many applications. Electric cars have recently changed from a niche novelty into a mainstream reality. The main reason for this is because of the decrease in cost and availability of batteries. What was once a very expensive component to produce is now much less expensive. Experts at Bloomberg Energy Finance predict that batteries must reach approximately $100 per kilowatt hour to produce. Current battery production costs are somewhere around double that, and at the rate that production costs have dropped, this goal should be attainable by the year 2025. Additionally, demand for electric vehicles continues to increase. A report from Bloomberg states that worldwide demand for electric vehicles will continue to increase rapidly in the next 30 years. By the year 2040, nearly half of new car sales are forecast to be electric vehicles, up significantly from the roughly 3 percent of sales that electric vehicles currently make up. Aside from transportation uses, batteries will also continue to enhance and improve the world’s power grid. Technologies such as wind power will be able to take advantage of improving battery technology by using batteries to store energy and release it into the power grid when electricity demand is high but wind production is low. This will benefit many types of renewable energy technology as the world’s energy consumption continues to rise.

light are being used to notify pedestrians of automated vehicle travel. It is
well known that automated vehicles are a thing of the future, and that future
is quickly approaching. The streets that have been shared by pedestrians and
vehicles driven by other people will soon be shared with vehicles driven
completely automatically. There are still many obstacles, literally and
figuratively, that must be overcome before driverless cars become a reality.
One of the main hinderances to future development of automated vehicles is the
dangerous or untrustworthy perception held by the public eye. How will
automated vehicles properly indicate to surrounding pedestrians the path that
the vehicle plans to travel? Jaguar Land Rover has developed a system that will
help to inform pedestrians of nearby driverless cars and their planned
behavior. The technology uses a series of light beams that are projected out of
the front of the driverless vehicle and onto the roadway surface. The light
beams run the width of the vehicle and spread apart when the automated vehicle
is traveling faster and move closer together at slower speeds. During
acceleration and braking, the spacing between the light beams changes, to
notify surrounding pedestrians of the vehicle’s planned actions.
Currently, Jaguar Land Rover is developing the technology concurrently while studying the effects of automated vehicles and the “trust” level that pedestrians have around these driverless machines. In order for the automated vehicle technology to launch effectively, pedestrians and the general public must wholeheartedly trust the actions of driverless vehicles. Jaguar Land Rover is studying how to increase this trust level. Current studies show that approximately 41% of pedestrians observing the behavior of automated vehicles are concerned about sharing the roads with robot-controlled machines. The projected light beams are designed to increase the public’s trust of driverless vehicles and will be a key safety feature for automated vehicles moving forward.

A competition to help influence new drone technologies is
being put together by Air Force Research Laboratory (AFRL) and the United
Kingdom’s Defense Science and Research Laboratory. The competition will find
the best drone design to help with fighting wildfires, and will use new drone
technologies such as drone swarms. The competition is being called the “Swarm
and Search AI Challenge: Fire Hack” and is designed to promote drone swarm
technologies used in a real world scenario. Drones, or Unmanned Aerial Vehicles,
are becoming more and more popular for many different applications. Their small
size and simple design bodes well for situations unsuitable for humans, and new
technologies are turning drones into massively capable little machines.
The idea of drone swarms is a relatively new concept. A
drone swarm would consist of a large number of independently flying drones that
are computer controlled. The drones would all be “aware” of each other to avoid
in-air collisions, be fully autonomous, and would be able to fly together in
close proximity, with the same goal of each delivering a small payload, perform
widespread searches of an area, of other related functionality. It’s easy to
envision how drones could be effectively used to fight wildfires: the drones could
deliver a fire suppression payload quickly and effectively, and a drone swarm
could cover a large area of wildfire.
Aside from the above mentioned usage, the Swarm and Search AI Challenge: Fire Hack competition aims to show how drone swarms could be used to effectively map out a wildfire area from a safe location. Benefits of using multiple drones for mapping include the ability to cover a large area quickly, and the ability to create almost real-time updated maps of wildfire spread in an area that would otherwise be too dangerous for firefighters to enter. Capabilities discovered during the challenge may be further developed for military applications. The competition will culminate in March, 2019.
