Option Pro (Good) Con (bad)
AM Works like pneumatics Same problems as pneumatics +
slow reaction time and
very low power.
EM No valves or hoses Big & heavy for same power as
pneu or hyd.
High power requirements,
Heat problems.
Hyd Most power for size Valves are very expensive,
High pressure available Leaks could be big problem,
Fast Very small cyl
inders
NOT available
LA Fairly strong Way to big and heavy for
android applications.
MW simple to operate Very little power,
no valves & hoses etc. SUPER SLOW (1 Hz or less).
Pne
u
Good power for size Gases are compressible so
Lightest for high power control is unstable.
fast High pressure NOT available.
Sv small, cheap & Very low power,
controller is cheap too Not as fast as steppers or
no valves or hoses etc. cylinders
St Small, fast Very low power unless geared.
no valves or hoses etc expensive controllers
