MAI Cup 2021/2022

At friday before this week we put our bot to a real-life-test. At first we had problems with the power source and the hall sensor but those weren’t the big problems we had at this day. We noticed problems everywhere: Like our bot suddenly stopping to work. Yes, we had … Weiterlesen …

In the past few weeks we have changed from the laser tof sensors to ultrasonic sensors since we couldn’t get those to work properly. We furthermore encountered some trouble with one gearbox that turns unreliably. We are also looking for new hall sensors for the magnet because ours don‘t work. … Weiterlesen …

Now for the last two weeks we all had holidays, but also lots to do because of our deadline today. So, one of our main advances was our new case of the bot. We now have 5 extra centimeters to house our parts and cables which we really needed. Now … Weiterlesen …

We held a tech dayfor the MAI Cup competition. All teams can prepare for the finals now.

This week we measured the power the bot needs all-in-all. Sadly, this doesn’t even give us any kind of information because the motors take more power, for example, in the moment they start. Also we didn’t find any information about our motor types so we can’t look up how much … Weiterlesen …

This week we again tried to connect the port expander, but it didn’t work as expected. We’ll try solving this problem next week. But we successfully connected our 9V battery to the DC-DC, so we can now use one battery instead of two. This also allows us to easily connect … Weiterlesen …

In the last two weeks we focused on tests about the floor and the magnet that’ll be used in the final maze. At first, we couldn’t connect the third infrared module because of a missing pin, but now we solved the problem by disconnecting a pin from the hall sensor … Weiterlesen …

This week we mainly planned our to-dos for friday. We’re planning lots of things like measuring the floor in the area the maze will be in, so that our sensors won’t think they’re a line, or testing how big the minimal distance the magnet that will be used for giving … Weiterlesen …

This week we focused on programming. So we had a close look at the bot: how the bot was following the lines, was turning right or left and was following the lines after turning right or left. We went on coding the bot. After uploading the code on the bot, … Weiterlesen …

This week we rebuilt the line sensors because they hadn`t worked properly. Finally, they do their job. We went on coding the bot. We coded more than 300 lines. The first code is almost finished. The bot can now drive through the maze. We are about to fit in the … Weiterlesen …
