Muscle Option Abbreviation 1. Airmuscle (rubber tube) AM 2. Electric motors EM 3. Hydraulics Hyd 4. Linear Actuator LA 5. Muscle wire MW 6. Pneumatics Pn eu 7. Servo motor Sv 8. Stepper motor St 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 Rating scale: H = high,heavy M = Medium, L = Low,Light F = fast, M = Medium, S = Slow Y = Required N = Not required V = very Table of Comparison of Muscle Options
