How do design a linkage arm for a servomotor controlled hinge mechanism?
Also how to choose the right servomotor?
While the servomotor is switched on, it is expected to hold a weight of up to 250g in its closed position. (Refer to Image for reference of schematic) (Refer to video for reference of the idea of the hinge mechanism)
I don't understand why you can't just do the same this that is on your own video link?
The one in the video did not really calculate and find out the linkage arm design or the servo motor spec so its difficult to adapt that to my application without knowing how it was done.
@MarkT with reference to your other forum...could you assist with this issue?
Sizing a servo for my project - does this motor have enough torque? - Using Arduino / Motors, Mechanics, Power and CNC - Arduino Forum
Well, your options are to test with a high torque servo and step up to at least a small geared stepper motor.
If you make a scaled drawing of the entire mechanism, you would get a better ideal. However the part left out is also important. HOW do you attach the servo to the box so it is not just waving in the air?
You also have to firmly attach the linkage arm to the servo shaft so the servo torque is applied to the linkage.
What experience do you have in building things?????
- Motor will be attached to a L shaped base. Btw, the box isnt the only component as it will be resting on another metal sheet so, there will be a part present to attach the motor
- Linkage arm will be attached via screws onto the servo motor, servo motors mostly come with an arm on it with through holes.
- Yes, I have experience making stuff, mostly mechanical so thats why Im unsure of the servomotor stuff
Servo is just a motor driven crank arm. A motor doing the work you would do to move the arm.
