Hey guys. I have a small ever I need to move occasionally in an instant back and forth motion. (The lever length is 3 inches and ROM is 90 degrees.) I would like to automate this so I can just press a button or send a signal. Would a high torque servo or stepper motor fit for this better? Also if you have an example for the mechanism itself it I would appreciate it.

My idea would be to have a motor turn it clockwise until it catches on a latch, and a spring that gets loaded by the motor to return it to 12 oclock once the latch is released.

Should I just attach a servo in such a fashion?

Sounds pretty good. You mind illustrating your idea?

possible
depends on the torque to turn the lever

assuming the servo has enough torque to turn the lever in the first place, wouldn't you be better off attaching the servo lever to the lever you are turning and mounting the servo somehow? This would give you 1:1 ROM.

Depends entirely on the load you're lifting, how often you'll be lifting it, and space constraints of your machine, but, OTTOMH I'd go with a crank and a high torque drive like pic related (not to scale or perspective). Use an end point switch at BDC of the stroke to tell your controller a cycle has completed, and to reset for the next stroke command. Stick with a 360 servo if you require to the degree precision or use a gearhead motor and switch if you want to simplify the control schema.

that's a fucking machine, isn't it?
