The tool
The tool itself is a mechanism to hit the other machines buttons. So we designed a tool to attach to the common base.
We started by designing a 3d sketch of it in Rhinoceros
The operation, consists on a motor that rotates a wheel with hands through a closed rubber belt. The motor is fixed to the base with a support that allows to tense the belt
Then we started the proccess of defining all the pieces in order to send them to cut.
Materials:
After we have everything clear and tested, we cut the pieces for the tool:
The result was good, and it did its work smoothly as it can be seen in the final video.
