DEVLOG #6

What I did

So today, I decided that I should finish up my design before I apply to get funded. But there were a few things that I had yet to do. First, I created the top panel for OTIS. I don’t exactly know why I put it off until now, but I made a simple design that will just sit on top and be held in place by little stoppers. I also did a bit of research beforehand on what battery i should purchase, but a lot of them are too big. So I also increased the size of OTIS from 77mmx77mmx77mm to 80x80x78.5 (78.5 because the lid is 1.5 mm thick). Lastly, I went and updated the assembly video and drawing, and uploaded all the changed parts to the GitHub repo.

Challenges

Resizing the robot

When I initially changed the size of the robot, I thought everything was ok. I used joints to attach everything, so all the parts just kinda “shifted” into the right spot. But the challenges came when I had to edit the parts of the robot that were now disproportionate. One example of this was the LCD. The screen is supposed to sit right in the middle of the robot, but it was not in the middle of the LCD board, which means all the dimensions got messed up when I resized the enclosure. To make matters worse, the project tool that I used to make the holes kept bugging out and offsetting the projection to where it was BEFORE I shifted the design. Eventually I got it to work by creating separate sketches from the projections, which is a setting on the pop-up. This way, the projections would stay exactly where I needed them instead of trying to auto-correct to some past position. I also fixed some other parts; the spacer near the servo also got messed up, but I was able to fix those problems much more easily.

What Is Next

The microcontroller and wires will arrive today, so I will begin working with them and the AI to figure out how to synchronize them all. I also applied for funding, so I will wait and see where that goes. Thank you.
