關於Servo選擇

選擇力矩的大小　＝　重心重量　X　重心到Servo距離　X　Sin（角度）

假設有一機器人上半身約重0.7/kg，而上半身到腳踝關節的距離是10/cm，當腳踝彎曲45度時，則： 0.7/kg * 10/cm * 0.707 = 4.949 kg/cm

M42接環與T-Mount接環

最近在玩這類老鏡頭，然後收到有一個Soligor 28mm/f2.8的鏡頭，想說接上Praktica MTL50之前先看一下螺紋是否有符合，用游標卡尺量了一下這顆的T-Mount接環大約是41.62mm，離M42還差大約38條，可是很神奇的可以合上相機而且無限遠有對到焦距，然後很好奇去爬文發現T-Mount其實也是M42，只是說牙距傳統的M42是1mm而T-Mount是0.75mm。
