AGVs can have many shapes and configurations depending on the load it is designed to transport. The vehicle type, load, and path are all used to determine the right drive type for the vehicle.
Automated Guided Vehicle (AGV) Drive Configurations by Type
AGVs can have many shapes and configurations depending on the load it is designed to transport. The vehicle type, load, and path are all used to determine the right drive type for the vehicle. Usually a vehicle has one or more Steer and Drive wheels with an appropriate number of supporting wheels. As an example, a vehicle can have one Steer Drive Wheel, and two supporting fixed wheels.
AGVs use a virtual reference point that affect the vehicle’s drive pattern and how the vehicle will be located on the start and stop point of a path. The system uses a global coordinate system for positioning components like reflectors, spots, etc. The vehicles reference point is also used together with the safety zone parameters to determine a vehicles safety.
Different types of drive configurations include:
Steer and Drive Wheel – A Steer Drive vehicle has both a steer and driving wheel which can typically turn 90° degrees in each direction.
Caster Wheel and Fixed Wheel- A caster wheel is usually a support wheel with no other function than to support a vehicle turning 360°.
Steer Drive Vehicles (S/D) – Steer drive is popular with many pallet vehicles. This configuration is normally one steer/drive wheel and two fixed wheels.
QUAD Vehicles – Mainly used where close attention is needed with how the vehicle is entering and exiting a station. This vehicle includes two or more S/D wheels and two or more supporting caster wheels.
QUAD Vehicles in Diff Drive Mode – An example of Diff mode is at stations where there is no space for the vehicle to turn around before entering the station. This is where a QUAD vehicle works by changing from 2*S/D to Diff mode; that is the steer drive wheel is rotated to a 90° angle.
Other Configurations – There is nearly an unlimited amount for configurations that can be achieved which are all determined by the task the vehicle should perform.
Transbotics can independently drive and steer 16 wheels in any configuration. This ability allows our vehicles to move in any direction without limitation on vehicle or load size. To learn more about AGVs or to find the right AGV solution for your business, consult with an AGV Specialist today.
