Transport trolley AGV

Agri - System integration - Mobile control

An automatic transport trolley for handling internal logistics in horticultural companies.

Background

Achterbosch Mechanical Engineering offers a wide range of technical services. From welding to machining and bending using modern CNC machines to developing and manufacturing complete machines. We have been working together for many years to develop total solutions for the internal logistics of pot and tray plants in combination with sprinkling, pouring or control. Combining our proven concepts with customer-specific customization creates a cost-efficient total solution for growers. Together with Achterbosch, among other things, we developed the transport trolley.

Despite its substantial size, the transport trolley allows flexible maneuvering in two directions. Thanks to the smart safety scanner, the travel speed is infinitely adjusted to the distance from obstacles. The high degree of robustness makes this transport trolley suitable for the demanding environmental conditions demanded in the horticultural industry. The modern controls make the transport trolley suitable for fully automating the internal logistics of horticultural companies.

Challenge

To develop an infinitely adjustable automatic transport vehicle to move planting materials in a greenhouse complex. In addition to performing automatic tasks, the vehicle must also be easy to use by hand. This demands a lot from the drive concept to be able to drive steplessly from standstill under full load in two directions of travel. The vehicle must be usable both autonomously and in combination with a central process control system.

Solution

The basis of the transport trolley is a solid frame with a generous battery pack and a powerful drive system. The solid rubber, profiled wheels ensure optimal performance on slippery floors, and a well-thought-out mechanism ensures a surprisingly small turning radius relative to its size.

The transport trolley is also distinguished above all by its modern controls. For example, the touchscreen can be operated remotely via a smartphone, routes are tracked precisely, the trolley positions accurately, wireless communication with the environment such as doors or production machinery is provided, and the control works optimally together with an optional central process control if complex traffic situations or business processes are required.

The standard size is 8 x 2m, this can be customized to a maximum of about 9.6 x 2m. Despite this substantial size, the cart can drive and position accurately in two directions. Our Ribotic navigation antenna is used for reliable positioning, induction loop tracking, RFID transponder reading and RFID transponder navigation. Using robust three-phase induction technology, the travel drive delivers high torque over the full stepless control range. The differential drive provides extremely precise steering behavior.
