attuatore lineare

-

buongiorno,
ho una domanda:in futuro dovrò realizzare un braccio meccanico portatile che da una posizione completamente chiusa si apra totalmente. siccome ho paura che servo non bastino (saranno abbastanza pesanti,sono per un cosplay),pensavo di usare degli attuatori lineari. qualcuno ha mai fatto qualcosa del genere?grazie!

tieni presente che l'attuatore lineare di solito è piuttosto lento (3-5 cm/s), in compenso è molto potente (spinta 50 kg), ma pesa oltre 1 kg.
