This paper considers engineering and educational challenges of the assistive robot contest RoboWaiter and interactions experienced by participants, both students and people with disabilities.

By designing, building, and operating autonomous robots students learn key engineering subjects and develop systems-thinking, problem-solving, and teamwork skills. Such events as the Trinity College Fire-Fighting Home Robot Contest (TCFFHRC) offer rich opportunities for students to apply their skills by requiring design, and implementation of autonomous robots that are tested during competition. Started in 2003, the TCFFHRC Robotics Olympiad offers junior-high and high school students, working alone or in teams, to demonstrate their knowledge by taking a challenging 50-minute written examination in four key areas related to robotics: mechanics, sensors, software, and electronics. The Olympiad comprises a second evaluation medium that supplements a regular contest survey, which has been in place since 1999. The contest survey solicits information about motivation and progress in subject areas from all contest participants--a large and diverse group that includes junior-high and high school students, working engineers, university students, and team supervisors/guides. As a further evaluation step, we have conducted supplementary case studies of courses and curricula at Trinity College and at the Technion. Assessment indicates that the TCFFHRC has achieved its primary goal: to foster and improve robotics education on an international scale.
