Re-building Servo motor

The last review help me come to a decision. First I decided the that the objects will be like living creatures and not living creatures behind fabric. this will be their first position:

They will be like cramped creatures inside themselves.

After they will engage with the viewer their "arms" will start to open in a random way.

In order to create this movement I need to create 4 arms for each object. I found this video:

Im going to print the different arms in the 3d printer

but the parts works with continuous motors and not the regular motors I have. So I needed to re build the motors and change their movement

In addition I started to work with the 9960 sensor as a proximity sensor

The plan for next week is to print all of the parts and to have at least one object working (without fabrication)
