Segway

Fascinating Mike,

Everyone knows about the Segway stand on rider unit, few have heard of the Segway wheelchair for the disabled.

Known as the Ibot 4000, and was introduced in advance of the Segway, it is a 4 wheel unit which can self rise and transport the occupant about on the two back wheels alone , I have seen one in action, it works on the principle of an inverted pendulum, the motor driven wheels react to maintain the centre of gravity above the wheel contact point.

Interesting fact is the travel range is greater when on two wheels than four according to publications.

The coolest engineering feat is that the wheels can go sideways and diagonal without the need to turn the vehicle.
I have seen the same principal used on some industrial conveyors.
Talk about an invention with the potential of making us all fat and lazy, but it also looks like fun. I wonder what the top speed will be?
The Ibot 4000 was a great invention, but they stopped making them from what I understand?

Wow...... Ive seen how to's to make your own segway, but that drive wheel would be hard to copy with off the shelf parts. I bet it may have issues with pea gravel or out door use.

The IBOT was a flop. When I was disabled everyone and their brother told me about it. Its great if it didnt cost 20 grand, had more than a 220lb weight limit and a range of rehab seating.

Interesting the segway isnt as popular as the stories and mystery that surrounded "its" release. Or for that matter knock offs.

I was searching ebay for electric wheelchairs and electric scooters. Came across 2 neat "scooters" that are self balancing. Both use gyros, fuzzy logic and lithium batteries. :evil:

One is a unicycle or monowheel like 190WH Electric Scooter 18km H Self Balancing Monocycle Moile Power Bank Charger | eBay

The other is a skateboard you ride sideways vs inline. WG01 Mini Smart Self Balancing Electric Unicycle Scooter Balance 2 Wheels Black | eBay

Lots of listings and variation of the uniwheel design. Seems all have similar specs, but the battery capacity and top speed varies with price. Lots of you tube videos on the single wheel model. If it werent for the fact the weight limit is 260 lbs Id give one a try.

Found the air wheel you tube channel. https://www.youtube.com/channel/UCEt-cdan_M-n4uvPrtg-Uyg they got quite a few products there for the US market. Seems on ebay you can order all of them, but they only have 3 for US.

Im torn between the airboard that has 2 wheels that you stand with your feet apart, then the one you stand with both feet closer together. TO make choosing more difficult they have some with 2 center wheels and some with 1 center wheel.

Ive always wanted a segway, but seems the price never came down even for used ones that are well worn. These seems to sell for less than 500 bucks and about 200 used with some minor damage.

personally i never have liked the idea of single wheel transportation. need to stop or swerve rapidly because someone steps in front of you? good luck. i hope it has training wheels for when you need to start, otherwise you need to find a place to sit to get on it. even if it is self balancing you are the thing that is out of balance on it.

Im still between the single wheel and the side by side one. The single wheel is about 275 and the dual wheel is about 400.

The videos shows you start up next to a wall and balance using it til you feel it out. I have riden a segway and imagine its a combination of that and a bicycle.

Seems they have a speed limit and alarm due to keeping balance. For example they are limited at like 12 km, but the absolute is like 19km but as you approach 12km it starts to alert you and pitch you backwards to make it slow down before it goes too fast to keep balance. Likewise when the battery starts to die.

I was going to use one of my mothers old rollators to feel it out and get use to it. Seems you turn it on so it sits level and once you put your foot on it and it rests against your inner calf its pretty stable.

Well, I won one in an auction on ebay for the price I wanted. Its the single wheel self balancing unicycle like. I got a cement pad out back Im going to learn on with one of my mothers rollators she no longer uses. Once I get the hang Ill go around the yard or maybe the mall or local walmart.

Ive always wanted a segway, but like mac computers they seem to hold their value for even a broken non functioning one. Ive visited the local science museum several times just to take a quick ride on the segway they have.

Its really neat how it can balance or move faster than you to keep the center of gravity where its needed. Its kind of like air bag technology. Its amazing how the signal can travel faster than your body when you enter into an accident and the bags are inflated to cushion the impact.

Here is one like I won TG T3 Self Balancing Monocycle Electric Unicycle Scooter Wheelbarrow to Airwheel | eBay Its heavy construction. The charger feels rather light and both have a nice new product smell. Plugged it in took an hour to charge up. Looked up the repalcement battery. Its a 60 volt cell lithium one. Looks like a shrink wrapped pack with no BMS of any kind. :confused:

I like how when you stand on it it braces against your inner shin/calf. With it on its neat how its self balancing. I fooled with it and to be 350 watts it feels rather strong. I haven not tried standing on it with it powered up. Im sure its like riding your bicycle for the first time and I want to be in an open area to run with it so to speak.

It is a bit on the heavy side so I cant imagine carrying it or getting the back pack to wear it to just travel the last km of your commute. I think the arm is a better option to wheel it like a piece of luggage if you are not riding it.

Thanks Sam. :-?

Interesting he had 2 fire extinguishers close by and wasnt afraid to use them. Interesting it left a streak on the floor. Wonder if it was modded, the video was staged or the lithium battery exploded like in soo many phones, laptops, etc due to poor construction?

I havent rode mines yet with the power on. I had ordered a folding luggage style handle to use. Ive seen Adam from one of the mythbusters episodes ride one of these and he had the handle bar attachment.

I have stood on it and practice mounting/dismounting and general balancing. Its low enough to the ground you can easily catch yourself if you are focused.

For the first time ever, the first YouTube comment is apropos.

"Once the scooter gets up to 8 mph... you're gonna see some serious ****."

Its a gearless brushless motor with a 14 inch tire on it. Most are rated at 350 watts. If the tire slips it enters fault mode, at least the model I have.
