(Waseda Kyotokagaku Elbow-No. )
1. Introduction

WKE-1(Waseda Kyotokagaku Elbow No.1) developed in 2011-2012 have following problems.
1) Thicker than the arm of adult women.
2) Maximum force in the elbow is insufficient.
3) Range of the elbow joint is insufficient.
4) Strength is insufficient because of the use of a wire drive system.
Then, the norm of the design was improved, WKE-2 for nerve medical examination training and involuntary movement in elbow was developed.
