A bit vague. Like hitting them with a hammer? Or launching large ball bearings at them? Or placing them in a compressed state beneath a seat cushion and having someone sit on them?will trigger some springs.
Linear actuators is more like what i am looking for but i need it to be strung out with decent power and be able to push it back to it's positionPhatFil wrote: ↑Thu Jul 19, 2018 11:11 pmmotors, stepper motors, linear actuators and solanoids are just a few of the devices you could employ to create motion on demand depending on the specifics its tricky to suggest which might be most optimal.
when looking to employ anything that draws more than a nominal current you will also want to consider if its compatible and within the capacity of the pi to power and if not employ a 2ndary power source.
Better, but still vague. If you want to compress a spring, then you need to know how much force the linear actuator requires and how long stroke to compress the spring That, in turn, will dictate how much electrical energy is needed and how to control it. So, it would be helpful to know more about the spring characteristics to calculate the mechanical and electrical requirements for the actuator.Linear actuators is more like what i am looking for but i need it to be strung out with decent power and be able to push it back to it's position
