Whether you're thinking about upgrading your existing mobile warehouse or just getting started on the road toward warehouse automation, there's never been a better time to invest in mobile computing.
One of the great things about technology is as time goes on, prices continue to decrease while available features and performance continuously improves. This is certainly the case with RF (Radio Frequency) based mobile computers. With so many devices to choose from and so many options available, selecting the best hardware for your organization can seem complicated and confusing. In this article we'll present an overview of the various hardware options available today and provide some practical tips on how to get started down the road to warehouse automation.
Two Types of Computers
There are basically two types of units to consider for automating data collection in your warehouse: handheld units and tablet PCs. Defining these two categories is the first consideration to be taken because it clearly divides the field from the outset.
Ruggedized Tablet PC
The ruggedized tablet PC is similar to wireless touchscreen tablet PCs used by business managers and office workers with one important difference. Unlike office-capable tablet PCs, the ruggedized version is built to military specifications and designed to operate in harsh environments. The ruggedized tablet PC can be mounted to a forklift or cart, attached to a fixed docking workstation, or simply carried by the user.
The ruggedized tablet PC has a larger screen than a handheld unit. The screen looks very similar to a laptop screen and the ruggedized tablet PC runs a full version of Windows XP. A major difference between a standard laptop and a tablet PC is that the tablet PC's screen can be used as an input via touchscreen. With touchscreen and handwriting recognition, the ruggedized tablet PC does not require a keyboard or mouse.
The ruggedized tablet PC typically uses a separate barcode scanner device that connects via USB cable. Generally the scanner attachment is a gun type or a pen wand style.
In summary, if most of the data collection will take place while the operator is working on a forklift or within a fairly limited area, the ruggedized tablet PC can be a great option. If the operator needs to spend a good amount of time walking around, the bulkier, heavier, ruggedized tablet PC may not be the best option.
Handheld Mobile Computer
As the name implies, the handheld mobile computer is designed to be carried by the operator. The typical handheld computer is small and light and can be worn on a belt and carried by the operator for an entire shift.
Handheld mobile computers come in a wide variety of forms from PDA-sized non-ruggedized units (great for light duty use and maximum mobility) to sturdier, fully-ruggedized units that can be used outdoors and in very harsh environments. Most handheld mobile computers have a built-in scanner and can be configured in a gun form where scanning a barcode is a matter of pointing the device at the barcode and pulling a trigger.
Unlike a ruggedized tablet PC running Windows XP, the handheld mobile computer runs the Windows Mobile operating system specifically designed for a smaller screen size, lack of full sized keyboard, and reduced computing power.
In summary, the handheld computer is a great choice if your operators need greater mobility and will be scanning information as a primary part of their job. If an operator's work area is on a hard surface like concrete or in a harsh work environment, consider a ruggedized unit to prevent damage from drops, dirt, and moisture.
