I would like to attach a horizontal bar to a servo so that the spinning of the servo can raise either end of the bar. The idea is to use leverage so that the servo could spin 60 degrees and the bar would turn 30 degrees but with more force. Here is my crude diagram:
0 < -- Servo Rotor
/ \
/ \
----+----- < Bar that moves up and down around "+" pivot, with weight on both ends.
I am mechanically challenged. Does anyone have any suggestions or examples using the servo erector set parts and standard size servos? Specific parts to use is very helpful.
Thank you
George
would love to help. do you have a drawing?
there aer meny parts in the ses range so most things are possible.
meaning?.. sorry i need a better explanation of how it works and why! what its the purpose?
like a swing?
The easiest way to do this is with gears or a belt system. It’s a simple 2:1 reduction. If you’re generating the servo pulses yourself (you can get 180° rotation from the servo) you can actually do more like 6:1 which will be a little slower, but much stronger. It looks like your diagram is using maybe push rods or something. This is possible too, but may be more difficult to implement. servo city has some gears for servos that might help you.
R.D. Thank you I will check servo city. I was thinking about gears but I wasn’t sure what that entailed.
Sorry I couldn’t put in a drawing, I would have to link it from a site and I didn’t have time. Next time maybe, let me see if I can find the gears.
Thank you both.
