Vibrobots - a technical question

All vibrobots I have seen use an offset, rotating mass to induce vibration. I have access to a motor with a reciprocating output. Would it be best to set the mass vibrating front-to-back of the vibrobot, or up-and-down? Or at some angle between the two?

Given a not perfectly balanced creation will be made, I assume it will move, regardless.....too much forward to backward reciprocating motion may have it toppling over. Too much vertical motion may only have it doing jumping jacks in place. Maybe you can build in some adjustability into the mount so you can make it go more often then ending up face down or face up, without having to rebuild it with each try. Allow for some hysteresis in it's highest portion of the jump and you will have it moving randomly about in no time :-)

Actually, I'm hoping for some directability.
Oh ok, A bit of a challenge then..... :-)

One presumes that the Zeroth Law applies...

But he's not asking if he should post, he's asking for design assistance...

And then, ~~if~~ when it works, I shall post (but not for 3 or 4 weeks, thanks to holidays - I'm away for a couple of weeks from Saturday).
All right! Aw...where to?

A week in Cumbria with my parents, then a week in Northumberland renting a cottage with friends.

I will be taking my little laptop, though, so I'll be "here" for the first week at least, and maybe if I get near a McDonalds in the second.

(For reference for non-Brits, I live in Suffolk.)
Awesome! (Haha you'll miss Gmjhowe, sadly...)

Oh, yay! Glad to hear it. :)

Yes, at...well, finding his address is half the fun of this website! I won't spoil it for anybody. ;)
