| - | 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 | + | |
| - | PWM角度制御が可能なサーボモータに対して、角度を次のように定義する。 | + | - 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. | ||
| - | - 最小幅PWM入力時における位置と、最大幅PWM入力時における位置の差から、10%を間引きした値を可動範囲と定める。 | + | An angle of a servo that is controllable by PWM, is defined below. |
| - | - 可動範囲の中点を90°と定める。 | + | |
| + | - 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]. | ||
