Omnidirectional wheels let an automated guided vehicle (AGV) move sideways and rotate without first steering its wheels into a new direction. By coordinating wheel speeds, a properly designed drive can combine forward, lateral and rotational motion. That helps a vehicle approach loads from different angles and maneuver in tight spaces—but the benefit depends on the wheel layout, floor, payload and control system.
How does an omnidirectional drive move an AGV?
Each wheel turns under motor power, while small rollers around its circumference redirect part of the contact force sideways. The rollers are not powered independently; rather, the vehicle combines the forces from multiple driven wheels. A controller sets each wheel’s speed to produce the requested motion across the floor.
With suitable geometry and synchronized control, the vehicle can translate forward or sideways, rotate in place, or combine translation and rotation. KUKA describes its production omniMove platform as able to move in any direction, including from a standing start. Its Mecanum drive uses independent barrel-shaped rollers and does not need to steer the whole platform to change direction. OmniAGV similarly says wheel-speed selection on its Aptius wheel can produce planar vehicle motion.
“Omnidirectional” describes a motion capability, not a guarantee that every vehicle can move in every direction equally well under every load or floor condition. Wheel geometry, traction, chassis layout and control calibration all affect practical performance.

What flexibility does this give an AGV?
Maneuver in a smaller working envelope
Lateral travel and in-place rotation can reduce the clearance needed for a turn or approach. Instead of making a multi-point maneuver, an AGV may be able to move directly alongside a rack, machine, trolley or fixture and then rotate to align. KUKA positions omniMove for precise movement in tight spaces and offers a modular system whose dimensions can be configured.
Fit the vehicle around the job
When the vehicle must pass beneath a trolley or work within an existing equipment layout, its height and the placement of its wheels, motors, bearings and battery matter as much as its turning behavior. OmniAGV describes an under-trolley approach in which the vehicle moves beneath a trolley, lifts it and transports it through a facility.

Separate travel direction from chassis orientation
A conventional steer-and-drive vehicle generally has to reorient its wheels or chassis to change its travel direction. A holonomic omnidirectional arrangement can instead translate sideways while keeping the chassis orientation, or rotate while moving. That can simplify approaches to constrained pickup and drop-off points, though the vehicle still needs enough clearance and traction to execute the commanded path.
Omni wheels and Mecanum wheels: what is the difference?
The terms are sometimes used loosely in product descriptions. In general, an omni wheel has rollers distributed around its circumference, while a Mecanum wheel has angled rollers—commonly arranged at about 45 degrees—and is often used in a four-wheel layout. Both can contribute to omnidirectional motion when wheel forces and speeds are coordinated. The names alone do not establish how a complete AGV will perform.

| Selection consideration | Mecanum arrangement | Omni-wheel arrangement |
|---|---|---|
| Typical wheel geometry | Angled rollers; commonly used in four-wheel arrangements. | Rollers distributed around the wheel circumference; layouts may use three, four or another engineered number of wheels. |
| What to assess on the floor | Roller contact, traction, vibration, scrub and sensitivity to unevenness. | Roller contact, traction and how the chosen layout distributes load; lateral resistance depends on geometry and installation. |
| Mechanical integration | Franke identifies minimum installation space, rigid bearing arrangements and higher tilting moments from eccentric loads as design requirements for Mecanum-wheel AGVs. | Check wheel dimensions and the mounting, hub, bore and motor interfaces against the chassis and duty. |
This is a design comparison, not a universal performance ranking. A wheel that works well on a smooth, level floor may be a poor choice where joints, debris or uneven surfaces interrupt roller contact. Compare complete vehicle layouts under the intended load and route rather than choosing by wheel name alone.

OmniAGV describes its Aptius wheel as an evolution of Bengt Ilon’s Mecanum wheel, patented under WO 2021/116847. The manufacturer claims that, at the same diameter, it can support significantly heavier loads, or, at the same load, use a smaller footprint. The published description does not provide an independently controlled benchmark, so treat the comparison as a manufacturer claim rather than a general performance result.

- Payload and load position: Specify the maximum payload, its eccentricity and the acceleration and braking loads. An off-center load changes wheel and bearing demands.
- Wheel and drive components: Confirm wheel diameter, roller material, bore, hub, motor torque and bearing rating. MECAWHEEL lists these as configuration dimensions and offers custom bores, rollers and hubs. Franke’s Mecanum application uses an LER2-120 double-bearing arrangement; Franke says its compact rectangular profile addresses load requirements and its one-piece plastic cage with retained rolling elements facilitates mounting in the wheel.
- Floor and traction: Check flatness, joints, ramps, contamination and surface grip on the actual route. Include transitions and turning areas, not only a representative clear floor.
- Required motion and stopping: Quantify lateral speed, turning radius, stopping distance and positioning accuracy. Validate these requirements with the loaded vehicle and the intended route.
- Packaging: Measure the required chassis height and clearance beneath or between pallets, racks, trolleys and equipment. Check battery, motor and sensor placement as part of the complete envelope.
- Control and navigation: Verify calibrated wheel geometry, synchronized drive control and navigation software that can command combined translation and rotation. Validate safety scanners, emergency stops and traffic management with the selected kinematics.
- Service access and lifetime cost: Plan access for roller, bearing, motor, battery and sensor maintenance. Include spare wheels and rollers, bearings, controls and commissioning when comparing full-life cost.
How do wheel and component suppliers fit into the decision?
Component descriptions can narrow a shortlist, but suitability still depends on the intended vehicle and duty cycle. MECAWHEEL presents more than 145 industrial wheel configurations and identifies Mecanum wheels for AGVs and robotic platforms, omni wheels for transfer movement, and hubs and accessories for shaft connections. Its listed configuration options—such as diameter, load, roller material, bore and mounting interface—are useful starting points for specifying a wheel.
OMNIA describes its industrial omni wheels as suitable for robotics, AGVs and AMRs, with an all-polymer design, polyurethane or Santoprene roller choices, bushed rollers and high impact resistance. It also describes integration with existing conveyor systems. These are supplier claims; confirm load capacity, floor compatibility and service life for the actual application rather than assuming a material or feature will suit every route.
When is an omnidirectional AGV the right fit?
Consider this drive when the task benefits from sideways approaches, in-place rotation or close maneuvering around fixed equipment, and when the floor and payload are compatible with the selected wheels. It is not enough to confirm that a wheel is called “omnidirectional”: the complete vehicle must deliver the required motion while carrying the load, stopping safely and remaining maintainable in its operating environment.
Manufacturer specifications and application examples show that omnidirectional platforms range from compact under-trolley vehicles to heavy-duty transport systems. They do not establish a market-wide figure for how much flexibility an AGV fleet gains. Make the decision against measured route constraints and vehicle requirements, and verify the resulting configuration with the supplier.
