Endo-Periscope III – Revolution from a Squid

Developed in 2003-2004, diameter 5 mm, steering range: ±110º in all directions.

Construction equivalent to Endo-Periscope II, however with Ring-Springs replaced by novel patented “Cable-Ring” mechanism based on tentacles of squid. The Cable-Ring mechanism consists of a ring of 22 steel cables (Ø0.45 mm) enclosed by two conventional coil springs, allowing only axial cable displacements to control the motion of the steerable tip. The Cable-Ring mechanism is entirely constructed out of standard parts and therefore very suitable for low cost mass production. The Cable-Ring mechanism is being commercialized worldwide by spin-off company DEAM.
