SAND FLEA!? help

boa
boa over 11 years ago

hello,

 

i am currently studying computer engineering and for my dynamics class i was asked to make a arduino based project that had to do with dynamics.

basically i want to make this:

https://www.youtube.com/watch?v=6b4ZZQkcNEo

 

image

With the modification that it will calculate based on the angle and the force, how high & long it traveled and with what acceleration & velocity 

It doesn't have to jump as much, it would just have to jump about 2m at most, the thing is that i know how to do the build, wheels, circuits, programming my weak spot is the mechanics that will make this thing

jump. I would really appreciate and helpful ideas/tips/comments/ on how to make this thing jump.

 

Thank you element 14 community

    Darpa probably spent millions of US dollars on that cute jumper! This is a huge task to replicate anything close. You should use rubber bands or a spring with a small motor to wind up the action. Forget…

    Hi Carl, I had one other idea. A while ago I noticed in a toy store they had a mechanical dog that went back on its hind legs and jumped, performing a flip before landing on its feet again. If you could get your hands on one of these you could hack the mechanism. If the force from the dogs flip were vectored through the center of gravity it would jump instead of flip.
