Heated Legos

 Halfbaked, indeed.

There are robot competitions which mandate use of onl Lego parts; no glue, tape or nonLego issue stuff is permitted. Sometimes a stressed Lego robot will shed bricks - especially problematic with long delicate claws and such.

I wonder if heating the Lego bricks before or after clipping them together would produce a stronger bond? This would not violate the rules against glue and exogenous materials but potentially would produce a very strong robot.

Ultrasonic welding http://en.wikipedia.../Ultrasonic_welding
nifty! Better than my idea. Except you need an ultrasonic welder instead of a cig lighter. [bungston, Feb 27 2010]

       I am thinking along the lines of heat-induced tack between peg and hole. Alternatively one could gently melt an entire little brick and use it as mortar, not technically violating the rules.

       Yup. I remember a red lego wall, got left in the back window of the car, turned into a fine tool for bashing my sister over the head.   

       I thing you're having a miscommunication with [21Q] - maybe if you made explicit that you'd allow the bricks to cool before applying stress...

       Ultrasonic welding could work too.

       fit them together then microwave spotweld the interior ? (in other words pretty well what Wrongfellow just said)

       perhaps lego should manufacture lego screws and bolts.
