The electric flexible videoscope was developed. The developed components of the videoscope are insertion tube, 360 degrees full articulation tip with joystick control, detachable probe part, camera module equipped with CMOS sensor and adjustable high-intensity white LED light sources. The insertion tube can have strong torsional rigidity from the components of spiral spring and tungsten mesh tube. The handset with joystick control makes it possible to manipulate the videoscope tip articulation in 360 degrees of all directions easily. Over 90 degrees of bending angle measured from the straight camera probe makes it possible to inspect the surface of side wall. The detachable probe model can separate insertion tube with probe. It is useful to select proper length of insertion tube. Several tests were performed to check the development objectives.
