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 it to move the flap automatically. This construction allows us to switch between two modes of the vacuum cleaner. One mode is supposed to suck in the balls into a pipe. The second mode should put the balls back into a basket. We are testing it and looking forward to making it work in the weeks to come.
