3D printed vacuum ejector: First test

After a previous prototype which didn’t work, I tried to make a new one.

This time I decided to start from scratch with a new design and using ABS.

I printed this part vertically to have better alignment in the main axis.

Although some reinforcement with acetone was needed, the prototype is ready to hit the lab.

This time a quick and dirty trial using the hand air gun.

The results are amazing!20150520_111807_HDR[1]Even without the silicon suction cups, this ejector was able to pick small and big parts.

More about this is still to come.

 

Presented Master Thesis about robot self-tooling

Today, Jose María Herrero presented his work about robot self-tooling.

Jose María Presented the Robot Self-tooling concept.

Jose María Presented the Robot Self-tooling concept.

This a new concept involving 3D printing and robotics, where a robot can build and change his fingers automatically.

This setup uses a 3D printer extruder and a fingerless gripper with two dynamixel ax12 servos. He also had to deal with VAL3 for the programming the staubli TX60, and made a program in Python to send the G-codes.

Good job, José María.
