This modular flying vehicle would then break apart in the air and then repeat the process over again but in a new randomly-generated configuration.
and created a linear dynamics model of the vehicle in order to provide us with some intuition about its physical dynamics.
Our initial hope was to demonstrate each of the key abilities using a single set of vehicles
in order to make the vehicle lighter for flight. Its primary limitation however was its inability to demonstrate coordinated mobility for randomly assembled configurations.
One additional revision of the vehicle was created prior to arriving at the current design. In designing Revision 1 one of our major goals was to integrate both driving and flying capabilities.
Although lightweight and mechanically robust the ethyl polypropylene foam chassis we used in the proof-of-concept vehicle was difficult to manufacture
when conducting experiments with our vehicle within the environment of a 3d motion capture system (needed for ground truth measurements)
and (2) measurement information (or control information) needed to be transmitted to the vehicle wirelessly for control purposes which at the time of development (using Wifi) generally incurred a lot of latency and packet loss.
and utilized an electrical bus to clean up the mess of communication lines we had in Revision 1. A detailed description is given in the next section.
Standard on most aerial vehicles is a 3-axis rate-gyroscope which is used for measuring body angular velocities as well as estimating the attitude of the vehicle in flight.
An infrared distance measurement sensor is used for measuring the distance of a unit to the ground.
Not only is used this for estimating the altitude of the vehicle but if units share their distance measurements with one another they can also estimate the vehicle tilt
when flying over a flat surface. We have designed each unit with magnetic interfaces located along each of its six sides.
in order to achieve flight â##without it the vehicle would simple rip itself apart before takeoff.
Thus each unit is generating the appropriate control effort necessary to keep the vehicle in flight
The only information that a unit needs for flight is its local sensor data and its position with respect to the vehicle centre of mass.
if each unit knows the physical configuration of the vehicle. In order for a unit to determine this on its own each unit can work out its relation to neighbouring units by sharing appropriate information.
By forwarding this information around the network each unit can arrive at the physical configuration of the vehicle much like how one might establish his/her family tree.
Assuming a rigid body for the vehicle which was taken into account when designing the chassis local sensor information provides a unit with a rough estimate of the vehicle tilt and altitude.
And knowing its position with respect to the centre of mass it straightforward to work out the appropriate control effort needed to counteract any disturbances.
We instead developed a means for automatically computing the tuning parameters for any flight-feasible configuration of the vehicle that would result in best flight performance.
In carefullly analyzing the parameters obtained for a variety of configurations we then developed a scalable method for mapping the configuration of a vehicle to its approximated optimal control tuning parameters.

Supervised traffic jam assist After a short day looking at robocars at CES a more full day was full of the usual equipment cameras TVS audio and the like and visits to several car booths.
Ie expanded my gallery of notable things with captions with cars and other technology. Lots of people were making demonstrations of traffic jam assist at CES simple self-driving at low speeds among other cars.
All the demos were supervised of a traffic jam assist. This style of product (as well as supervised highway cruising) is the first thing that car companies are delivering (though they are also delivering various parking assist
and valet parking systems). This makes sense as it an easy problem to solve. So easy in fact that many of them now admit they are working on making a real traffic jam assist
This is a readily solvable problem today you really just have to follow the other cars
and you are going slow enough that short of a catastrophic error like going full throttle you aren going to hurt people no matter what you do at least on a highway where there are no pedestrians or cyclists.
As such a full auto traffic jam assist should be the first product we see form car companies.

The most impressive car is Delphi a collaboration with folks out of CMU. The Delphi car a modified Audi SUV has no fewer than 6 4-plane LIDARS and an even larger number of radars.
It helps if you make the radars as otherwise this is an expensive bill of materials.
With all the radars the vehicle can look left and right and back left and back right as well as forward
Called Project Wing, the system was based on a mechanically simple ailsitterdesign a hybrid vehicle that takes off vertically like a multirotor
For fast forward flight, the vehicle tilts to a near-horizontal orientation, resulting in efficient lift production due to the conventional wing design.

#Google Self-driving cars Ready for Public roads Google announced Friday its self-driving prototype cars were ready to leave the test track
in a step forward for its autonomous automobile program. The move comes after Google's internal testing of the bubble-shaped vehicle over the past year
and more extensive experience with technology adapted for existing cars.""Now we're announcing the next step for our project:
this summer, a few of the prototype vehicles we've created will leave the test track and hit the familiar roads of Mountain view, California,
with our safety drivers aboard,"said project chief Chris Urmson in a blog post.""We've been running the vehicles through rigorous testing at our test facilities,
and ensuring our software and sensors work as theye supposed to on this new vehicle."
"The Google car uses the same technology as its fleet of Lexus SUVS which has logged some 1. 6 million kilometers (one million miles)."
"So the new prototypes already have lots of experience to draw on--in fact, it's the equivalent of about 75 years of typical American adult driving experience,
"and during this next phase of our project we'll have safety drivers aboard with a removable steering wheel, accelerator pedal,
and brake pedal that allow them to take over driving if needed, "Urmson said.""We're looking forward to learning how the community perceives
and interacts with the vehicles, and to uncovering challenges that are unique to a fully self-driving vehicle."
"Google said earlier this week its adapted vehicles on the road had been involved in 11 minor accidents, but that none were the fault of the technology.
That included being hit from behind by other cars or sideswiped p

The distance between the car coils and road coils can be up to 20 centimeters (7. 8 inches) for the technology to work,
which limits their usefulness for cars with larger ground clearance. The system aims to provide several options to EV owners,
Scientists in the UK, for example, are developing electric highways to charge electric cars. However, unlike other options, this coil system from Fraunhofer Institute can also discharge the electricity stored in a vehicle battery

#Sonic Tractor Beam Levitates Plastic Beads The future, apparently, is going to be loud. In what is being termed the world first sonic tractor beam,
researchers in Britain have developed an acoustic hologram that can hold, move and manipulate objects in mid-air.
Tractor beams have been a reliable staple in science fiction movies like tar Wars, where theye used to reel in uncooperative Rebel blockade runners and pesky Corellian freighters.
The tractor beam developed by the U k. team uses high-amplitude sound waves and works on a much smaller scale.
Hence the tractor beam effect. Similar freestanding haptic holograms have been developed previously, but without the precision required to hold an object in place
The sonic tractor beam could have some interesting applications down the line, according to the research team.

#Daimler unveils first self-driving truck approved for U s. highway testing The future of self-driving commercial vehicles is unclear,
but the lure of fewer accidents, reduced fuel costs not to mention less human error have generated excitement in the trucking industry as well as the transportation safety sector.
The Daimler Inspiration Truck will be tested rigorously on Nevada roads as the company gathers data about the truck performance
Daimler is the parent company of Council Lead Partner Mercedes-benz, which also is working on next-generation vehicles,
including hybrid electrics intended for city use. What different about Daimler truck? Self-driving work rigs are not new.
You can see them on farms in the form of grain harvesters and planters; and mining operations use them too.
But those vehicles aren't designed to operate alongside other cars and trucks on the highway.
The Inspiration Truck has been licensed by the state of Nevada to do just that share the roads.
Autonomous trucks could provide several advantages for the trucking industry. They could dramatically reduce the chance for human error,
The savings in fuel costs would come from the truck's ability to accelerate and decelerate more gradually than humans normally do.

#An Electric car Heater Can't Be Too Thin or Too Economical Just about every electrical device seems to want to slim down to a thin filmf possible,
Its first application will likely be as a heater in an electric car, which, unlike conventional vehicles, can exploit the warmth of air that been passed over an internal combustion engine.

#Business models For Cars Need To Evolve Beyond Ownership Annie Hsu is the strategy director at global design and strategy firm frog.
A host of new car sharing and ride-hailing services have chipped away at the landscape of car ownership over the past several years.
Alixpartners, a global advisory firm, estimates that car sharing services have cannibalized sales of 500,000 vehicles over the past decade,
U s. car sales in 2014 totaled 16.5 million units. These estimates do not even account for the impact from ride-hailing services such as Uber or Lyft.
Many car manufacturers are responding by concentrating efforts on improving the product itself, incorporating new features from semi-autonomous driving modes to interior scent release.
