Omnidirectional wheel
In Allseitenrädern (also omnidirectional wheel ) is the tread of the wheel of rollers, whose axes of rotation at right angles are to the rotational axis of the main wheel. This allows the wheel to be moved with little friction in the axial direction.
On the one hand, these wheels are used in mobile robotics for omnidirectional drives . These robots usually have three driven omnidirectional wheels, the axes of which intersect in the center of the robot. By driving the wheels at different speeds, the robot is able to move in any direction and perform any rotation.
On the other hand, omnidirectional gears are used in conveyor technology . Similar to the roller conveyor , an entire area is equipped with omnidirectional wheels. Goods can then be moved and rotated on this surface with little effort in any direction.
The Mecanum wheel is constructed in a similar way to the all -side wheel , in which the rollers are attached at an angle to the main axis (usually 45 °). As a result, the rotation of the wheel and the rotation of the rollers cannot take place separately from one another.
