Valued throughout the world for their rugged versatility, Rovver® robotic crawlers include a distinctive modular design. The camera, control unit, cable reel and lighting are interchangeable on all three models, enabling a quick change from a 10 cm (4 in.) diameter to a 76 cm (30 in.) pipe in minutes with the same tool. Rovver robotic crawlers deliver full directional viewing in a horizontal pipeline with their pan-and-tilt or forward-only viewing color video cameras. Both cameras have remote adjustable focus, providing a clear view at all times.
