Make a machine, including the end effector, build the passive parts and operate it manually.
This topic was carried out as a part of group work. I joined to
group with Eino and Jari from Fab lab Oulu. We will publish also
our group
pages.
We talked a lot, what would be our machine. Individually and
together, we studied other earlier works and talked solutions. One
machine would be mechanics of a 3D scanner. The second might be a
walking machine. This idea inspired us. Maybe, three leg machine
can walk. Even, it turns left and right and go backwards.
Eino made a big work to prepare cutting plan and cut parts for
two linear actuators from cardboard and me and Jari assembled the
parts. It took several times. Especially, the lead screw and the
nut, how to fix them in place.
We need one more actuator for a walking machine. Also, a chassis
of the machine we need. First time I used color codes to control
laser power. We didn't engraved anything, only limited the power
for folding lines. Eino studied the correct values: cutting speed
90%, power 100% and frequency 35% for cutting (blue lines) and
speed 100%, power 50% and frequency 30% for folding lines (red
lines). We used Epilog Fusion CO2 laser with 75
Watts of power.
