This week we take a number of important and urgent decisions regarding the construction, shape and programming the robot.
First, because the price of the solenoids that will be used as "fingers" is obscenely high ($ 230.00 MXN c / u), we chose to reduce the number of actuators 24 to 19 (7 in harmony and 12 in the melody), thereby maintaining the idea of \u200b\u200bplaying a keyboard and discarding the instrument change that arises as an alternative solution.
springs were tested to achieve the solenoid return to its original position (which as we saw there was a need for mobility between octaves) and it was observed that when using a spring 1.5cm (for the race to be stem 1cm) gives sufficient strength, however we expected to have speed was reduced greatly.
But a spring 1cm (which allows us to have a career of .5 cm) has an acceptable speed, but the shift was not enough to press a key. One solution proposed is to move the solenoid but inside the key (rather than at the end) so that, under the laws of trigonometry, it requires a shift to push it lower.
Evidence continues. 70 days left ...
