First, we cut an OSB board to the appropriate size and attached the motors to the underside. Then, we drilled two large holes in the board through which we fed the cables. Next, we attached the microstep drivers to the top using Velcro strips and screwed the Arduino board in … Weiterlesen …

In the last weeks we thought a lot about our camera detection system. We had an idea to find the middle point of all cans, so we can drive to this point and pick up all cans at the same time. We do this by finding the middle point of … Weiterlesen …

Last week we redesigned our superstar so that it now has an emergency stop on all sides if it falls off the lifter-SIMA. In addition, it now has enemy detection and can move on its own with the help of a monowheel. Also, we solved a specific problem with the … Weiterlesen …

In the last week we managed to get the camera detection to work. That means, we can now detect ArUco tags from a distance and tell, how far they are away from the main lens (see video). The next steps are to calibrate the camera more and to make the … Weiterlesen …

We managed to create three individual robots, as you can see on the picture. The left one is the current prototype of the superstar – it will be lifted by the right robot in the picture – our lifter SIMA. For testing purposes, we use the middle SIMA to test … Weiterlesen …

In the last week we managed to get a camera to work with our raspberry pi, that will detect ArUco markers in the future. This currently doesn’t work like we want, but it already detects aruco markers in the camera stream. We plan to use this feature with the cans, … Weiterlesen …

Over the last few weeks we spent our time building SIMAs. We now have a larger SIMA, which we are currently using to test how we lift the superstar onto the stage, and a smaller SIMA, which we use for general testing. We have also already tested the speed of … Weiterlesen …

This week we have continued to work on our SIMAs. We have now created a complete 3D model of the SIMA. Once we had designed it, we started to build the upper part of the SIMA. The chassis and the buttons of our test SIMA are completely finished, we will … Weiterlesen …
