其實即使要做linear
你個motor係入面都係rotation,
最後叠埋啲belt drive/lead screw果啲先會出linear
pneumatic 同electric 個取捨我覺得係你個project spec
同埋筆直
pneumatic一個只可以去兩個位
再多你就要加stopper
或者叠埋兩個pneumatic
咁mech design難度上就會增加
Electric 成個panel就會開始加好多野
controller/IOs 有時要攞個大啲既power supply
不過控制上就多左好多野玩
multi position, speed, acceleration 係electric 上都易控好多
仲可以玩埋啲咩push force confirm
價錢比起用pneumatic隨時三倍起跳
stepper同servo我都係睇要求
servo generally 快啲大力啲
start-stop類都會揀番stepper
