-サーボモータに関して、基準座標は次のように定義する。
+## Basic Definitions
-- 歯車のついている側面に対する法線ベクトルを、y座標に関する正の向きと定める。
+Reference coordinates for servo motors is defined below.
-- 前述のベクトルに対して、右ねじの向きを回転の正の向きと定める
+- A normal vector which extends from the side of adding a gear, is defined as a negative vector of y axis.
+- Rotation direction for a positive vector of y axis, is subject to the right-hand rule.
+An angle of a servo that is controllable by PWM, is defined below.
+- Range of movement is defined as differences between an angle when input min PWM and an angle when input max PWM.
+- The neutral angle of range of movement, is defined as 0 [deg].
+## Specifications Each PLEN's Servos Have
+- **PLEN1.4**
+  Rotate clockwise by increasing PWM width.
+- **PLEN2**
+  Rotate counter clockwise by increasing PWM width.
