Creditors who say that ReconRobotics Inc. owes them $9.5 million have asked a federal court to put the robotics firm into chapter 11 reorganization, the Minneapolis Business Journal reported yesterday. Edina, Minn.-based ReconRobotics' creditors include Winona, Minn.-based RiverStar Inc. and Rushford, Minn.-based RiverBend, affiliated companies both listing Stephen Craney as president. RiverBend, a manufacturer, said in court filings that it's owed about $3.05 million for unspecified goods. Supply-chain management business RiverStar says it is owed about $5.38 million for goods.
