Extreme Offroad Tracked Wheelchair AKA ‘Ripchair’

18 Nov2014
OffRoadFlex

People in wheelchairs want and should be able to go where anyone else does, and that includes over rough terrain. But sometimes, traveling in an SUV isn’t an option, which is when the Ripchair comes in handy. It is a vehicle that allows you to load pretty much any powered or self-powered wheelchair inside, thanks to a loading bay that measures 50 by 30 inches, turning it into a mini off-road monster with large, aggressive treads. It’s a solution that keeps up with ATVs, meaning that wheelchair users don’t have to miss out on any outdoor excursions.



While the design might look brutish, it is actually pretty advanced. Made of aerospace grade aluminum, meaning it’s both strong and lightweight, the Ripchair weighs in at only 1,200 pounds. The hydraulics and tracks are construction grade, and the draw bar pull is rated at 1,000 pounds. A four-stroke engine pushes out 29 horsepower, which is more than enough to overcome most obstacles. It also has a ground clearance of 10 inches, which beats out what you can get on most stock SUVs. While it can hit speeds of up to 17 mph, there is a governor that keeps the chair from going more than 10 mph. In short, the Ripchair will get you where you need to go safely.




According to Howe & Howe Technologies, the vehicle can take on all sorts of terrain. Among the surfaces listed are loose sand, rocky areas, and forest floors. When it comes to traveling through snow, it can safely traverse through as much as 18 inches of the white stuff. Even ice isn’t a problem, when picks are installed. Wheelchair users can even ford small streams in the vehicle, making it the ultimate way for them to get around in the great outdoors. The Ripchair is also incredibly maneuverable and is able to perform a zero turn, which really comes in handy on tight trails.One of the best things about the Ripchair is that it can be customized in a number of ways, so it can be used for more than just traveling around in the wilderness. For example, an optional snowplow attachment allows users to clear a driveway, private road, or any other area quickly. A 5,000 pound winch can also be added, which is handy for recoveries when the chair or other vehicles get stuck somewhere. D-rings can be attached to the front and back, providing four tow points on the vehicle. Various cargo management systems can be added. For the avid outdoorsman, there is an optional fishing system from Ken’s Power Caster, or an equalizer shooting system designed by Jeff Malloy. Those that enjoy upgrades to their vehicles will also be pleased: this off-road chair isn’t a no-frills machine. A standard package can come with niceties like a holder for a fishing rod or hunting rifle, cup holder, a class 2 receiver, controls that are customized for the user, plus front and rear lights rated at 4,000 lumens.

Chinese Drone Maker DJI Unveils More Powerful Model

SAN FRANCISCO—China’s SZ DJI Technology Co., aiming to expand its edge in the global market for commercial drones, unveiled a more upscale model for professionals and an initiative to let developers create apps for its devices.
DJI on Wednesday said it would start this month selling the Inspire 1, designed as a more powerful model than its Phantom line of camera-equipped, four-rotor helicopters, which have gained wide popularity since debuting in early 2013.
The Phantom’s success with hobbyists as well as filmmakers, construction contractors and other professionals has made Shenzhen, China-based DJI the largest company by sales in the burgeoning commercial-drone market. Executives said the Inspire is aimed at addressing needs of those professionals that the Phantom can’t.
“The Phantom’s been pushed to the absolute boundaries of what it can do,” said Eric Cheng, DJI’s director of aerial imaging.
The new model carries a 4K camera—able to capture footage with about four times the picture quality of traditional high-definition cameras like the Phantoms’--that can turn 360 degrees while filming. DJI plans to sell it for around $3,000, compared with roughly $1,000 for the Phantom.

DJI CEO Frank Wang, creator of the Phantom drone, speaks from the company's Shenzhen, China headquarters about DJI's start and the future of unmanned aircraft.

Both the Inspire and the new application-development platform announced on Wednesday illustrate DJI’s ambition to enable large-scale deployment of its devices by companies as well as individual consumers and professionals.
The platform lets outside programmers create apps that control the device and the information it gathers. DJI said it already has joined with with several software companies to create apps for the Phantom, including one that uses the Phantom to gather data to create three-dimensional maps of the terrain below, and another that lets users coordinate simultaneous flights among several Phantoms.

The world's biggest consumer drone manufacturer unveils its newest model, The Inspire 1, which features high-def video streaming, simultaneous dual control and 18 minutes of flight time on a single charge. The new drone from DJI will cost between $2,899 and $3,399.

Mr. Cheng said future apps could help farmers analyze their fields or help emergency workers search for missing people. DJI said that for now, developers will only be able to write apps for the Phantom, but that it would likely include the Inspire in the future. Any user can create apps to control the drone’s camera. However, because of safety concerns, users have to apply to DJI to create apps that control the actual device.
DJI’s two biggest rivals among consumer-drone makers, 3D Robotics Inc. of California and Parrot SA of Paris, also are wading into the commercial space with devices that are designed for surveying, farming and other industries
The efforts currently are constrained by Federal Aviation Administration policy, which allows recreational drone flights in the U.S., but largely bars them for commercial use. The FAA is finalizing rules for commercial drones, expected in the next one to two years, that could enable wider drone use—or, if too restrictive, could threaten industry’s development in the U.S.
Even with the current policy, many U.S. entrepreneurs are using drones commercially, and other countries, like Canada and Germany, have begun to open their skies to commercial drones.
The Inspire also seeks to appeal to higher-end users with a camera that is detachable, so they can attach upgrades, such as high-quality sensors for applications like crop monitoring. The Phantom’s camera is largely locked in a front-facing position, but the Inspire’s camera can rotate 360 degrees. That movement is enabled by legs that rise into a V-shape after takeoff, leaving the camera below the craft with an unobstructed view.
During a test-flight by Mr. Cheng, the Inspire was noticeably faster and more agile than the Phantom, quickly coming to a stop from full speed in midflight. After demonstrating the Inspire, Mr. Cheng powered up the Phantom and took it for a spin over the trees. “Man, now this feels like a toy,” he said.
