:!: The "grabber" bit it might be more use on Andy's "Cuddle" as a tub extractor/loader.
Got your ears on Andy
I really don't gnow whather to say "thanks" or to curse you. Firstly, for anyone who doesn't know, Mindstorms was what gave rise to the Cuddle project in the first place.
Secondly, the video is a great example of how much fun this stuff can be and also for me a reminder of the heady days consulting for a mobile phone company on home automation. If we wanted to go get a pager, an internet ready server on a SIMM chip (TiNi) and a cheap camera to try make a webcam that could be stuck on a window and accessed via WAP (anyone remember that?) the money came out of a petty cash box and we went and did it.
I watched it several times because I was having difficulty following hte commentary and their enthusiasm reminded me of the U Utrecht team that built an internet clock using a Mindstorms set to make a clock with moving hour and minute hands, then pointed a webcam at it. Good job my German isn't better, because otherwise I'd have missed the clever bit about the grabber (intentional or not on their part. but I think deliberate since I don't see it in the earlier prototype.)
If you look closely at "it starts to work", there's a certain amount of play in the grab head as it runs in and out of the chassis. This actually reduces the number of outputs required by one, allowing the use of the light sensor as well, with a standard Mindstorms without any of the multi i/o kludges that are floating around. (Anyone who's looked at my Yard of Straight Track will recognise the colour combinations
I'm not sure if this can be used with a tippler, but I'm on the case.
