Since I'm starting to test different configurations this week, it would be easier if we could change the control accordingly. Right now, I've successfully adjusted forward/backward/up/down control even people have messed up with the wire connection in the wrong way. This is pretty useful since in...

I'm testing different motor + propellers combinations since we change our control board to feather board esp32. And I will use feather board as the development toolkit in the paper, so it's necessary to test these combinations because the thrust and weight are the input parameters to our system. ...

We had learned from the non-ML-based ball detection algorithm that a color-and-contour-based algorithm cannot always detect the ball with enough accuracy. As a result, I have been developing an ML-based platform for training a model with multiple images of the ball and identifying a bounding box aro...

Last week, the engineering effort was focused on setting up the hardware and building the blimp and any other required electronic components. Initially, we couldn't set it up using the balloon that we bought from Amazon, so we had to reuse the blimp that was used in the previous tournament. Due to t...

Over the past week, I have been working on getting the dashboard to display video. As shown in this image, the dashboard can now do so. To do this, one can pass in JPEG binary data or base64 encoded JPEG images, which it will then display. I do this by having the OpenMV cam send this info to the...

I have been working on allowing the user to review their robots runs within the dashboard. There is now a Download txt file button at the top of the screen, which allows one to download a text file containing a JSON object that represents every input the dashboard received. However, this currentl...

I have built the first prototype of a boat with rudder steering. This video shows the rudder steering in action. We ran the boat four times and obtained these results: When the rudder is straight, the boat goes (relatively) straight. When the rudder is tilted to the left, the boat veers to...
