Hi beautiful people
concept:
to cut down on personnel for upcoming shows, i want to park a robot infront of a piano and have him sway back and forth and have the arms move. then I can use a prerecorded kybd track and it will sort of “look like” the robot is playing.
the robot is R.A.D. 2.0. a late 90s toy.
the arms move using a 6VDC motor and gears.
problem:
I need a circuit that will operate the motor in one direction for 1-2sec then reverse direction for 1-2sec
I have surmised that one route is using a dpdt relay to switch the pos and neg to the robot, but how do I add a timer circuit to this?
space inside is limited.
my plan is to have a push switch that i can step on to activate the entire circuit.
push once: arms begin to swing open and close
push again: arms stop
can anyone please help me?
i’ll be reading, but could use some guidance.
I am not sure if a microprocessor is the right route, because of the need to power it off and on quickly.
additionally, anyone with insight into how to dampen the noise from these plastic gears or the motion in general?
thank you!!!
this will be so cool eventually.
I am going to add some blinky light stuff or maybe a sound activated light situation for the eyes.
I plan to have the robot sway to and fro by maybe hacking apart an oscillating room fan and repurposing.
