This week we wrote an algorithm for our ultrasonic sensors to remove some noise from the sensor. This is important because the sensors aren’t always quite accurate, so we must filter the values. In the algorithm, we have a variable “a” to adjust the graph. If we make “a” smaller … Weiterlesen …
In the past weeks we got our bottom plate. we can start building the first prototype of our bot: Additionally we completed the full aluminum case which we are going to install the hardware in: (author: Lucian)
In the last week we finally managed to finish our model of the base plate so it’s now ready to be milled. We also updated our 3d model so it now fits our needs. We also got our motor holders printed, and some important parts we need to start building … Weiterlesen …
This week we thought about the communication and the tasks of our two Raspberry Pi Pico. Our idea is that one board we’re going to use for reading out our sensors, calculating what the motors need to do, and sending these instructions with some parameters to our second Pico, which … Weiterlesen …
This week we successfully built the suction system for picking up the cake plates. We can now lift objects up to a weight of 150g comfortably and don’t worry that it will work with the actual cake plates which weigh 100g. We also tested our distance sensors which work great. … Weiterlesen …
This week we have ordered parts we need for the small bot. We improved the 3D-model by mending the middle decks. Besides we created holders for the decks and other aluminum profiles. We built a small box. The box contains a moving flap inside. We also attached a servo to … Weiterlesen …
This week we started with developing a cherry dropping system which can accurately drop cherries on the cakes. This system is also designed to have a hopper mounted on top of it so it can hold 10 cherries in total. After that worked well, we started to design the lift. … Weiterlesen …
In the last productive week we finally finished our first 3D-model of the small bot, and we’re really confident that our plans could work out. In this design, there’s already the vacuum cleaner in it, a color sensor for following the lines, ultrasonic sensors, which will be in the walls … Weiterlesen …
