GuardCom enables Mobile Industrial Robots (MiR) to communicate directly with conveyor stations

VISSENBJERG, Denmark – Wi-Fi instability is a common workplace challenge. In material handling applications with devices communicating through complicated setups passing data around between mobile robots, third-party receiving stations and conveyors, an intermittent Wi-Fi network is prone to cause costly errors and downtime.

Having witnessed these connectivity issues first hand, ROEQ is now launching GuardCom, a communication solution that enables Mobile Industrial Robots (MiR) equipped with ROEQ’s top rollers to communicate directly with conveyor stations to initiate the transfer of goods between mobile robots and conveyors.

The solution consists of two products; GuardCom installed on the stationary conveyor station, and GuardCom Connect installed on the autonomous mobile robot.

Multiple GuardCom Connects can work with the same GuardCom and vice versa. GuardCom is compatible with all stationary conveyor stations, replacing third-party wireless devices.

Once the mobile robot has arrived at the conveyor, GuardCom signals to the stationary conveyor station that the robot is in place and ready to receive or deliver the packages, same signal is simultaneously sent to the robot letting it know that the stationary conveyor is ready. Once the transfer task is completed, both units receive a signal that it is safe for the robot to leave. 

The GuardCom is integrated into the stationary system with a handful of cabled connections. The handshake process between the GuardCom and the mobile robot is completely wireless.

To prevent misplaced or dangling packages, GuardCom includes a physical guard installed on the conveyor station that goes up to prevent packages from rolling off and dropping to the floor when the autonomous mobile robot is not ready to receive. An alarm alerts the operator to come onsite to remedy the situation – or for the conveyor to roll backwards automatically.

Hartfiel Automation, a U.S. distributor of ROEQ products, sees the GuardCom system as a shift in the way robots are deployed. “In the past, significant engineering development and  third-party hardware was required to manage the logic of moving material from a stationary conveyor onto a mobile robot, which added substantial cost and time to deployments,” says Scott Albrecht, VP of Advanced Control Technologies at Hartfiel Automation.

“With the ROEQ GuardCom system, these challenges are minimized or eliminated resulting in lower risk, lower cost, and faster deployment for these users.”
