Bedford’s iRobot Corp. said Tuesday that it has received a $7.7 million order from the Naval Sea Systems Command, or NAVSEA, for robot upgrades.

The order calls for software upgrades and the delivery of advanced sensor suites for 248 fielded Man Transportable Robotic System MK 1 MOD 1 robots, the company said. The company said it expects to complete these deliveries by November.
