| Research Abstract |
The prototype of Robot Arm was developed and verified of practical use and problems.
●For easy sterilization, the parts of arms and movements are separatable from the substance.
●The folding system of the vertical shaft were changed from screw fixation to rachet ball.
●The power transfer system of a zoom axis was changed into the gear drive from the friction drive, and smooth operation of it was attained.
●The connector was changed so that it could connect easily by one-touch.
●The radius which a horizontal axis moves was changed into 150mm from 200mm, and it has improved so that an arm may stabilize and move.
●The experiment of operation was conducted using the animal. The opinion of the doctor of other institutions and an endoscope maker was heard, and it has checked that it was practical apparatus.
As for operating an arm using a button, it is a problem that a way operator's consciousness will separate from an operation field. Therefore, it took into consideration adding the function to operate by speech recognition. The experiment with the assistant robot which added the speech recognition mechanism under development independently was conducted, and it was a problem that reaction time is late.
●A voice directions command needs to shorten.
●It was thought that English expression currently used daily should have been used like "OK" and "Good".
●In the voice recognition system which used the personal computer, a limit is in shortening of reaction time. Then, it is necessary to develop the system which specialized the function more.
