Flexibility across the entire area for driverless transport vehicles

Whether in warehouses, production facilities, hospitals or offices - battery-powered automated guided vehicles (AGVs) are in demand wherever material flows. Especially when they not only drive on predetermined lanes, but can navigate freely across the entire area and also carry heavy loads. To do this, however, the transport vehicles must be able to recognize obstacles and drive safely around them. The basic prerequisites for this are high-resolution sensors, powerful drives, low-backlash mechanics and omnidirectional steering in the smallest of spaces.

The drive is the key
How flexible a driverless transport vehicle is depends primarily on its drive concept. ArgoDrive is a drive and steering system that is currently setting standards in this area. It combines the strengths of common drive concepts such as differential/armored steering, Mecanum, turntable and steering motor and is also IIoT-capable. It was developed by ebm-papst, the technology leader for air flow and drive technology.

ArgoDrive combines a superimposed gearbox with two powerful EC motors, omnidirectional steering, sensors and all the necessary connections in a single unit. Nevertheless, the system is extremely compact in its dimensions.

Both motors contribute to steering, accelerating, driving or braking as required. The infinite steering angle of the gearbox enables unlimited maneuverability. This means that a transport vehicle equipped with ArgoDrive can turn and turn from a standstill, even drive crossways and maneuver smoothly, space-savingly and with millimetre precision. Even when things get tight or the type of floor covering changes.

Strong performance in every case
As a rule, two ArgoDrive drive-steering systems are required per transport vehicle. Two freely movable support wheels provide the necessary stability. However, if very large or heavy loads have to be transported or if gradients of up to ten percent have to be overcome, three or four of the drive-steer systems may be required.

To meet all requirements, ebm-papst offers ArgoDrive in three variants: Light, Standard and Heavy. For weight classes up to 100, 300 and 500 kilograms respectively and for different ground clearances. If four ArgoDrive Heavy are installed on a transport vehicle, the AGV can move up to two tons of load. For example, it can maneuver an entire car body from A to B in the case of a modular production facility.

With ArgoDrive, nothing stands in the way of modern intralogistics and flexible material flow. And if a fully loaded pallet does block the lane or another AGV crosses it, the sensors and braking unit react immediately.
