Adam:

This week I was mostly a helping hand for Jacob and assisted him in most of the assembly, like putting parts together, drilling, crewing and advisor in terms of how to proceed next. We have also met with multiple teacher that were a big help to our work.

Adrian:

Now that the arm is assembled, I worked to test each joint and servo motor to make sure the arm can move as intended. At the end of the week and on the weekend, I’ve given the arm to test it’s strength and moveability. Some servo motors had to be replaced. Others weren’t the correct version. However, even with all the right servo motors, with the power Arduino gives out, it wasn’t enough to power all of them at once. Then, with an external power supply, it still had difficulties even with the max voltage I dare to give, which was 7.2 volts. At the end of the week, I gave the assembly to Farah to continue simulating and looking into integrating image recognition.

Jacob:

This week I took charge of the assembly. I first I put together the new reprinted model, then when I found out we didn’t get screws. After we got screws we found it the holes were too tight or they were not there at all. So I took the assembly to the machine shop and drilled some bigger and more precise holes. Then with help from Adam I screwed in the claps for servomotors. When I was screwing in the motors and immediately testing them, we found out out that some could have been damaged or not working properly. We met with almost every teacher in the school this week to help us with variety of things, but ultimately I was able to put the assembly together and gave it to Adrian and Farah for further testing.

This week Sergi and I tried to do the FEM analysis in the most critical position, which is when the robot is in a completely horizontal position and tries to pick up a certain weight.

However, we noticed that the robot hardly suffers from the force of the weight of the bottles it has to pick up. This made us realize that we were doing the FEM wrong.
