Buy Omni Wheel

Omni wheels or poly wheels, similar to Mecanum wheels, are wheels with small discs (called rollers) around the circumference which are perpendicular to the turning direction. The effect is that the wheel can be driven with full force, but will also slide laterally with great ease. These wheels are often employed in holonomic drive systems.

A platform employing three omni wheels in a triangular configuration is generally called Kiwi Drive. The Killough platform is similar; so named after Stephen Killough's work with omnidirectional platforms at Oak Ridge National Laboratory. Killough's 1994 design used pairs of wheels mounted in cages at right angles to each other and thereby achieved holonomic movement without using true omni wheels.[1]

They are often used in intelligent robot research for small autonomous robots. In projects such as VEX Robotics, Robocup and FIRST Robotics, many robots use these wheels to have the ability to move in all directions. Omni wheels are also sometimes employed as powered casters for differential drive robots to make turning faster. Omniwheels are often used to allow for movement on the horizontal axis on a drivetrain, as well as forward and backward movement. Usually, this is achieved by using an H-drive.

Omniwheels combined with conventional wheels provide unique performance properties, such as on a six-wheeled vehicle employing two conventional wheels on a center axle and four omniwheels on front and rear axles.[2]

Blumrich claimed that the design is described in the Book of Ezekiel as a component of a spacecraft created by extraterrestrial life, which is why the wheel is sometimes jokingly called the "Ezekiel wheel". The Spaceships of Ezekiel describes his process for the "discovery" and recreation of the Omni wheel as well as a traveling craft and its docking station.[3]

The 60mm Aluminum Omni Wheel is a robust, durable and double row wheel that provides easy 360 movement, with rotational and sideways maneuverability. It includes 10 rubber rollers, the rollers are mounted along its circumference and the rubber rollers to avoid slip.

Omni-Directional wheels roll forward like normal wheels, but slide sideways with almost no friction (no skidding during turns). Use these wheels to make your robot turn smoothly or build a holonomic drivetrain.

These Omni-Directional wheels were designed from the ground up to give the smoothest ride possible. Our construction method, using a dual roller design, allows for a constant contact patch with a narrow profile. Each roller is tailored for the individual wheel diameter, and provides the correct, constant radius. We don't share rollers between wheel types -- these wheels aren't "almost round" they're actually round. This smooth-ride provides higher efficiency and reduces wasted power!

Omni-Directional wheel assembly hardware is separate from sprocket mounting hardware. Sprockets are screwed into captive 8-32 standoffs. This allows for easy removal and replacement of sprockets without disassembling the entire wheel. No more worrying about your whole wheel falling apart just because you wanted to remove the sprocket.

Omni wheels or multi-directional wheels are the types of wheels which can move in any direction. With the use of rollers or sometimes called discs, they are able to rotate at 360 degrees, roll to sideways smoothly and also act as a regular wheel moving forwards and backwards. Rollers are small mostly rubber-made wheels placed at certain points with the same distance on the wheel.

One of the most important use of Omni wheels is in robotic competitions. There are many drivetrains designs which robotists have to choose from in order to create their robot according to the specific competition requirements they signed up for, but a robot with H-drive or holonomic drive are the two drivetrains which require Omni wheels to be able to move in any direction. In these designs, four or five Omni-wheels are used and placed at the corners of robot chassis at a certain degree in a way that the wheels are non-parallel to the chassis.

Omni Wheel, also known as Poly Wheel, it is similar to Mecanum Wheel. Omni wheel are very unique because they are able to move in many directions with small discs around the wheel that rolls with full force, and will also slide laterally with great ease.

Because each Rotacaster omni-directional wheel acts independently, multiple wheels and layouts can provide extra manoeuvrability and be customised to meet specific load weight and distribution requirements.

The 38mm Omni Wheel was designed as an odometry wheel that can fit inside most channel sizes. For ease of use, three cores were designed to fit 6mm D-Shaft, 5mm Hex Shaft, and 7mm Hex Shaft. The wheel is open for easy use in any ecosystem with the provided different-sized cores.

DUO Omni Wheels are compatible with the REV DUO System and have rollers mounted around the outside which passively rotate at 90 degrees to the powered direction of the wheel. DUO Omni Wheels can be used to make it easier to turn with skid steer robots or can be used to make more advanced robot drive trains like kiwi drive. DUO Omni Wheels can be double stacked to create a continuous outside roller surface.

The (4 inch) 100mm Double Aluminum Omni Wheel is a robust, durable and double row wheel that provides easy 360 movement, with rotational and sideways maneuverability. The 100mm double plate aluminium omni wheels have some rollers mounted along its circumstance and the rubber rollers to avoid slip. Each roller has two bearings allow the wheel to move smoothly and easily in ANY direction.

I set out to test all three options, beginning with good old fashioned pedal power. The Omni Wheel did not disrupt the handling or feeling of the bike. I felt like I was riding along on a regular bike and could even forget I had the option to switch to power. I was using the 700C version, which starts at $1,000 and according to Evelo, returns 15-25 miles of range, depending on how you use it. 26-inch wheels are also available.

Currently existing in prototype form, Poimo (that's POrtable and Inflatable MObility, obviously!) is made out of thermoplastic polyurethane and inflated with the aid of a small pump. It reportedly takes just one minute to inflate Poimo to its fully blown-up form, before the wearer/driver adds the remaining rigid components such as wheels, brushless motor, battery, and handlebars. Then they simply hop on, and they're off to the races -- or, at least, to the office. The creators have a short video on YouTube showing the Poimo in action.

Thanks but if you look at the link I sent, you will see that only two omni-wheels come in the products I bought. Imagine I had a standard drive-base: would you suggest two omni-wheel at the back (where the motors are and two normal wheels at the front, or would you suggest I buy more omni-wheels.

It will affect how the bot turns, so it depends. The center of rotation is between the traction wheels. You could try the traction wheels on the front and back and see what you like better. For this game I would think to probably put them on the front of the bot so the center of rotation is closer to the risers that you are placing. That would allow you to be more accurate with your placement.

if i were you i would get more omni wheels. i say this because you can do so much more with them. for example with traction wheels you are stuck doing a tank drive. but if you have 4-5 omni wheels you can create x drives, tank drives, H drives, and kiwi drives. 3 of the drives allow you have side ways and diagonal motion this is a huge advantage. also the traction wheels have a tendency to warp. the omni wheels allow you to spin about the center which is extremely advantageous be cause it allows you to be much more agile which is very important for this competition .

The UNI-CUB was first introduced in May 2012 as a new personal mobility device featuring balance control technology and an omni-directional driving wheel system (Honda Omni Traction Drive System) which originates from Honda's research into humanoid robots, represented by the research and development of ASIMO.

The front wheel features the Honda Omni Traction Drive System. The rear wheel moves laterally to facilitate turning.By leveraging this layout and the different rotational speeds of the front and rear wheel treads during lateral movements, UNI-CUB can move forwards and backwards, side-to-side and diagonally and also turn in place, making possible quick, nimble movement.

Honda has taken the balance control technology it developed in its robotics research to the next level. Thanks to optimized wheel shapes, higher-precision control of drive power and posture stabilization and more stable maintenance of vertical position, riders can enjoy riding UNI-CUB in barrier-free indoor environments with peace of mind.

Add the ultimate mobility to your robot with the 96mm Dual Omni wheel. The Dual Omni wheel has two complete wheels fully assembled and ready to install with 12 high grip rubber rollers. Includes 2 polycarbonate wheels with zinc plated hubs & set screw.

I'm specifically looking at something which can support in excess of 100kg/wheel, so around 400kg in total. Also, a possible mission profile would include a 300 meter excursion outdoors on asphalt path, so they should be a little durable. The only ones I can find online are small ones for experimenting. 041b061a72
