A ribbon-cutting and open house are scheduled Saturday, July 9, at Blueroof Technologies Smart Cottage in McKeesport.

The handicapped-accessible "smart" house at 400 Spring St. -- designed for seniors and others who want to live independently -- will be open from 10 a.m. to 1 p.m. and by appointment.

Federal, state, county and city officials who provided grants and aid to Blueroof will attend the ribbon-cutting, as will James Osborn, executive director of Carnegie Mellon University's healthcare robotics center.

CMU recently announced an agreement with Blueroof to use its model cottage as a testing ground for devices that help physically and mentally challenged people. The technology comes from a consortium involving CMU and the University of Pittsburgh.
