Pounding Mallet

[klunk]

Hi all,

I hope I've come to the right place, I need some help in the making of a mechanical/robotic object. I need to make a large scale pounding mallet that can repeat a pound every 5 seconds or so. I'd be using a mallet approximately 300mm in diameter. It would pound away at a large cube of compounded dirt - a mud brick of sorts - that is roughly 1.5sqm or so.

i did a very rough sketch of what i assume it will require:
2 x a frame supports on either side of the mallet
1 x rod attached

I also assume that some weight bar will be required on the end of the mallet stick to allow for a pendulum like motion.

If I've come to the wrong place, sorry. If not, I hope you can help. So sue me for being an artist.

Best

something like this...? http://homepage.mac.com/sami_ashhab/courses/strength/subjects/impact/impact.html

but it should be stressed that this is a temporal piece of equipment being made for non industrial use. it'll be used for a visual art exhibition, so the materials are preferably cheap and easy to assemble.

cheers

You've really come to the wrong forum for this -- this forum is for industrial robotic systems.

Still, a decently-balanced system should be able to work with a fair-sized stepper motor and an Arduino board or something similar.  Industrial-grade hardware for most of this would likely be too expensive to be practical. 

If you have a hackerspace or similar in your vicinity, that would be a good place to start.
