After following the building instructions contained in the Lego Mindstorms NXT set, I wasn’t sure what to build next. I asked my wife and she said she wanted a robot that could fetch biscuits on demand. I thought about this for a while, and got to work. This is the result:
Now, it doesn’t actually fetch the biscuits, but it does produce them on demand. Once the hopper at the front is filled with biscuits (digestives are particularly effective) then you need only reach forward for a delicious snack and the perfect accompaniment to a cup of tea will be pushed out to your waiting hand.
It is likely though, that this convenience could be taken for granted and the biscuits will run out quicker than expected. For this reason, the light sensor on top of the biscuit stack will detect the presence of suitable confectionery. When the Biscuitron’s stock is depleted, it will not dispense anything and will apologise for the inconvenience.

Cool a cookie dispenser. How many cookies can it hold?

The only limit is the biscuit sensor arm, so I guess about 20 or so.
Unfortunately the Biscuitron is now dismantled in favour of a bigger project I’m planning on posting about soon.
do you think you will put building instructions and the program?
