Bot Sugar Bowl

Hopefully, this will work - this time. About 5 3/4" diameter, in poplar, is a simple somewhat familiar object - that behaves in a very unfamiliar way. when the lid is lifted off - or there's a loud noise in the vicinity of the sugar bowl - it waddles away - stops - and looks and listens. There's a little autonomous micro robot called the CRAB, by HexBug, underneath the bowl. It has a light sensor and a sound sensor, a little tiny electronic "brain" and a motor that opereates the crab's legs when either light or a loud sound is detected. The challeng of turning this piece was getting its weight down to 62 grams - a bit over 2 ounces - the maximum carrying capactiy of the CRAB. The cross section of the piece is that of an overhanging rim bowl - with an upside down bowl inside - the latter to hide the micro robot under. Did a lot of light turning - weighing - turning a little bit more - weighing - put a light inside and check for really thin areas - turning then sanding some more - weighing . . . Challenging piece to turn and really fun to watch reactions to it.

      Life is short - and then you die. There ARE times that require being serious - but they're usually rare. The rest of the time - when possible, enjoy and have some fun. If you can cause a smile, or maybe an outright laugh - why not? Lord knows, we can use a little levity these days.
