MAI Cup

In the holydays we finally wired up our new rechargeable battery, which now works really well. We also worked on our idea about the line following mode, so we can concentrate on it if it’s necessary. This code snippet also works really well, so we had extra time to set … Weiterlesen …

This week we’ve worked on the accuracy of the color sensor by creating a diagram. We also created a script which shows us when our sensor can detect a line and when it can’t. Now we can see which figure goes with which colour. We’ve also came up with a … Weiterlesen …

This week we focused on installing the color sensor, so we soldered the cables and wired it up. We also changed the code so we can see its output, the color values, right away. Now the only things left to do is to test it on the black lines and … Weiterlesen …

As seen in the videos we are currently testing the robot in different situations and improving the code accordingly. We think we could run into some problems with the infrared sensors, but we will find a solution for that. We still must implement the hall sensors for the magnet detection … Weiterlesen …

In this week the color sensor arrived and we already started testing it. We now know that this sensor is compatible with our set of parts and it really is working well. Now we just have to install it in order to use it as a detector of the final … Weiterlesen …

In this week our new color sensor arrived. At first we planned that we’d be only using it to detect the target zone, but because we already have a problem with our infrared-sensors, we thought we could also use it for the main line-following-code. We also tested this sensor and … Weiterlesen …

As seen in the video we are now able to test drive our robot. The bot’s electronics is mostly finished so we don’t have to worry about that anymore. The plan for the next week will be to be able to drive trough the maze without touching the walls. We … Weiterlesen …

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 …
