John Parker, president of Integrated Robotics Imaging Systems in Kenai, removes a more than 12-pound battery on Thursday from his Infotron coaxial rotor unmanned aerial vehicle, which recently arrived in Kenai from the France-based company. Parker is the North American representative for the company and returned from maintenance and flight training on the UAV in France about a month ago. Parker plans to integrate the UAV with collision avoidance radar developed at the University of Denver of which he has the exclusive patent rights. Photo by Kaylee Osowski/Peninsula Clarion
