Adam:

Nothing much has happened this week, me and Jacob have redesigned a few parts of the jaws, assembled them and patiently waited for the rest of the arm to be completed.

Adrian:

I decided to hardcode movements into the Arduino IDE to have something ready for testing, even if this method wasn’t my original goal. I made two different programs to test the complete assembly. One program uses buttons on the keyboard to move individual joints and servos, while the other utilizes a joystick. The X-axis controls the rotation of the base, while the Y-axis extends and retracts the arm.

Jacob:

Me and Adam assembled the redesigned mechanical claw, but sadly the redesign of the whole arm was not ready, so we could start the assembly. In the meantime we prepared stuff for the assembly.

During this week while the computer science team was testing the arm movement they noticed that one servomotor wasn’t working so we had to remove it and change it. Also we changed 2 continuous rotation servomotor to the standard ones, because for the programmers it’s easier to programm and also we don’t need continous rotation motors in the arm. So the arm servomotors are now standard ones (180 deg).

Also during this week I watched some videos on how to make a FEM analysis becasue in my case I have never done it before so it was completly new for me.

Some of the videos that I watched are the ones that follow:

The FEM analysis is a very important part, to be able to see how much weight/force the robot can lift and also to find the most weak points or parts of our robot, were is easier to break.
