Segway Centaur Concept

(from Segway Press Release) Like the mythical half-horse, half-man of Greek lore, Concept Centaur combines the best of several technologies to create an innovative whole. The result of exploration by Segway LLC's product development team, Concept Centaur will challenge the way you think about four-wheeled transportation.

From time to time Segway's product development team devotes days, or even weeks, to creating new product concepts with the goal of finding a prince among frogs. It's a product exploration process they call "frog kissing." During this time, engineers and designers are encouraged to use any available materials in a very short time frame to prove a concept will work.

Recently, the product development team demonstrated that Concept Centaur was a prince—a concept that passed this initial feasibility test, but is not yet ready to become a product. Concept Centaur demonstrates Segway's continued commitment to breakthrough innovation and the innumerable possibilities for the future of personal transportation.

Concept Centaur combines proprietary dynamic stabilization technology with advanced propulsion and suspension systems, and an intuitive user interface to create a unique four-wheel device that is easily controllable on two or four wheels. Its full suspension and aggressive rider positioning provide an exhilarating ride for one or two people while maintaining control over a variety of terrain. Its rugged performance, zero emissions, and quiet operation make it a good low-impact way to explore the world. Its power and versatility make it suitable for a variety of indoor and outdoor recreational and commercial applications.

Intuitive user controls:

Thumbs forward: The Centaur's forward and backward propulsion is easily controlled by pushing a thumb throttle located on the underside of the right-hand handlebar.


Pop a wheelie: The Centaur uses dynamic stabilization technology to limit and/or maintain the angle at which the rider experiences the device. What would normally be a dangerous maneuver on a motorcycle or ATV becomes safe and controlled on the Centaur. In addition, the rider can position his/her body in three different ways, which makes for a fun ride. This technology also allows for a high-performance design with a short, compact wheelbase - a combination that traditionally can be very difficult to control.


Lean forward, go forward: If you've haven't yet experienced the Segway HT, now is the time. If you have, you know what we mean by intuitive controls. Concept Centaur uses dynamic stabilization in a similar way. When on two wheels, the Centaur is controlled by how the rider shifts his or her weight. To go forward, lean forward. To go back, lean back.

Simultaneous mechanical and drive-by-wire steering:

Smart steering: The front two wheels turn left and right mechanically, which is made possible by an innovative linkage system designed by Segway engineers. The Centaur's advanced controls software also allows the rear wheels to turn at different rates in response to data received from the rider's steering direction. When on two wheels, steering is accomplished in the same manner, by turning the handlebar. Sensors in the vertical portion of the steering column monitor the rider's input and sends a signal to the controller boards, which then issues a command to drive either or both of the rear wheels. Turning rate is coordinated so that even with the wheels off the ground, Centaur follows the path defined by the front wheel angles. This allows smooth transitions between two-wheel and four-wheel operation.

Environmentally friendly:

No exhaust: Batteries power the Centaur, which means that there are no emissions. In addition, the Centaur uses regenerative braking, which means the batteries are recharged during deceleration and hill descents.


Quiet: Electric motors and an innovative gearbox design result in a quiet ride.


Low-impact tires: The Centaur prototypes use the same non-marking silica-based tires as the Segway HTs'. These tires are smooth, which allows the rider to perform exciting maneuvers while having little impact on the terrain.

Distinctive design, elegant suspension:

A profile X-shape: The profile of the Centaur creates an "X." Right after the Centaur was crowned a prince by the engineers, they quickly pulled in Segway's industrial design team to integrate their vision into the product's form and function. What resulted is a concept with a sleek minimalist design that elegantly showcases the rider, leaving the simple mechanical elegance of the underlying design visible.


Three shocks: There are three shocks on the Centaur that absorb bumps and help the wheels maintain contact with the ground. There is one in each front "arm" and one in the rear.


Lightweight: Concept Centaur only weighs about 150 pounds and can be easily transported in the back of a large SUV or small pick-up truck. If developed, its light weight would allow for transport on the back of small cars through a hitch-mounted rack, similar to that used for carrying bicycles.

How fast does it go?

Concept Centaur prototypes have gone just over 20 miles per hour. If Concept Centaur were to be manufactured in the future, more testing would be required to determine the appropriate top speed

Spark Design PALV Concept

(from Spark Design Press Release) What happens if you cross a gyrocopter with a car and a motorbike?

The PALV. A personal air and land vehicle. A solution to increasing congestion in our cities, highways and skyways.

On the ground, the slim line, aerodynamic 3-wheel vehicle is as comfortable as a luxury car. But has the agility of a motorbike, thanks to its patented cutting-edge ‘tilting’ system. The single rotor and propeller are folded away until the PALV is ready to fly.

Airborne, the PALV flies under the 4,000 feet (1,500 m) floor of commercial air space. With land and air space reaching capacity, this is some of the last free space.

The PALV is highly fuel-efficient and powered by an environmentally certified car engine. It runs on petrol like a conventional car and can reach speeds of up to 200 km/h both on land and in the air.

Its straightforward autogyro flying technology means that the PALV is economically and technically feasible in comparison to other forms of air travel. Like a helicopter, it has a Very Short Take Off and Vertical Landing (VSTOVL) capability making it possible to land practically anywhere. It can be driven to the nearest airfield or helipad and, because it flies below 4,000 feet, can take off without filing a flight plan. The autogyro technology means that it can be steered and landed safely even if the engine fails as it descends vertically rather than nose-diving. Lift is generated by the forward speed produced by the foldable push propeller on the back.

At less than 70 decibels it is much quieter than helicopters due to the slower rotating of the main rotor. A licence to fly the PALV is more accessible than one for a helicopter or plane because of the regulations controlling autogyro craft. In the United States and soon in Europe the infrastructure is in place for ‘digital freeways’ that provide a safe corridor using GPS technology to aid regulation and avoid collisions for low flying vehicles.

What makes the PALV attractive is the convenience of fully integrated door to door transportation. Providing smooth transition from road to air without having to change vehicle. The versatility to allow the driver to change their mind.

Such flexibility and independence would appeal to business and recreational users alike. Its capacity to reach destinations inaccessible by road combined with ability to fly low means that the PALV has potential applications from first aid/search & rescue to surveying and observation. Or simply offers a new personal experience.

John Bakker, a Dutch entrepreneur working closely with Spark design engineering and other partners, is developing the PALV. The concept was inspired by living in one of the most world’s most densely populated countries, with a can-do approach to space issues.

Private jet ownership is becoming more popular in affluent society. With further investment this hybrid prototype can pave the way for an affordable and feasible alternative. Soon private flying will no longer be the exclusive domain of executives and celebrities. If congestion or obstacles block the destination – fly. If the weather is too bad to fly – drive. Driving and flying combined in one vehicle that could cost little more than an executive saloon car.

but what would all the ricers do ?


IT ALREADY COMES WITH HUGE WINGS :)

On a serious note, coudl you imagine the line of lawyers if these things took to the air ?????

hahaha... that helicopter thing is funny... who would actually want to buy that? :D
wouldnt the blade be a bit dangerous tho if u let it off outside where there are people around?

it was that concern that had me thinking the lawyers woudl be lining up to handle the law suits. But thinking about it, that coudl be a good idea. Get all those lawyers lined up and then land beside them. All those empty heads flying woudl be fun :)
Lawyers - hate 'em !!!!

It's not a new idea.

in the late 40s, 50s and 60s there was the "Aerocar".

It cruised at 120 mph (193 kph) in the air.
In 1970 Ford Motor Co. even considered marketing the vehicle, but the decade's oil crisis dashed those plans.....

You could take off the wings and the tail with the propeller and carry it in a trailer.
