WiFi-free AMR communication

08 April 2021

ELIMINATING THE risk wifi communication can present in terms of unstable connection and resulting operational inefficiency, RARUK Automation has introduced GuardCom for its range of MiR autonomous mobile robots (AMRs).

Developed by ROEQ using proven sensor-based technology to remove the robot’s reliance on wifi, GuardCom connects directly with any model of ROEQ top roller modules and to the stationary conveyor station, enabling safe, fast, reliable and cost-effective handling and transfer of goods between conveyor stations. 

As communication is directly between GuardCom and the top rollers, no complicated and expensive implementation procedure or third-party system is involved. 

The basic system comprises of GuardCom and GuardCom Connect which are affixed to the stationary conveyor station and the top roller unit respectively.  A minimum complete solution would require two GuardCom and one GuardCom Connect which would enable the AMR to receive goods from destination A and deliver them to destination B.

Additionally, GuardCom safeguards against misplaced or dangling goods, by allowing the user to either programme the system to set off an alarm to alert a human operator to remedy the problem or set the rollers to roll back automatically.  A physical guard is also provided to stop goods falling off the conveyor station accidentally.

Communication between the GuardCom modules is a secure and safe wireless connection. GuardCom Connect signals to the stationary conveyor station through the GuardCom that the AMR is in place and ready to receive or deliver goods.  The guard is then lowered so transfer can commence.  Once the process has been completed the AMR receives another signal to move on to other stations.

GuardCom has been designed to be plug-and-play so it is quick and easy to set up; no costly commissioning time is required.  And because GuardCom is a small unit with sensor technology that connects directly with the stationary conveyor station it occupies minimal space by comparison to other solutions.  Overall, the system lowers the barrier to automation for any manufacturer or logistics company thanks to its simplicity and low cost.
