"keyboard" has many meanings. Please clarify which one you mean.
And describe the expected function.
Example: computer keyboard.
Do you want to press a single key and never any other (to test how many strokes the key can survive)
Or you need a single sroker to be moved over the whole keybord to be able to press every of the more than 100 keys
Or ten stroker that emulate two hands
Or one stroker for every key
Adjustable stroke speed or adjustable force
How to be controlled? Electrically, pneumatic,
What lifetime to you expect?
This kind of user interface.
I want to program different predetermined exercises sequences in this walking machine, so I need some apparatus for doing the keystrokes.
Let say I want a predetermined exercise routine (five minutes at 10mph 10degrees, 3 minutes at 8 mph 6 degrees, etc) so I only press 1 button (with an aditional interface) and the device will do the respective keystrokes in that panel.
I'm thinking about doing this with solenoids , but may be there's a better idea from y'all.
