SAND FLEA!? help

boa

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:

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

    Hi Carl - Here are some thoughts. Keep the mass to a minimum as each gram of added mass will increase the force that has to be delivered to make it jump. To simplify you might want to consider a one shot mechanism that you can *** like a mouse trap that can be triggered once. The force to make it jump has to be delivered through the center of gravity or you will just spin it. If the force is delivered through the center of gravity at a 45 degree angle to the horizontal you should get the most lateral distance for a give force. Since any force producing mechanism that can be put into such a small device will have a fairly short action distance in which to deliver the force it will have to be done quickly.  Another idea would be a CO2 powered piston controlled by a solenoid that can be triggered by the Arduino. This might give you multiple jumps. I loved the video. This is one of those devices that look simple but are actually very high technology. Sorry I can't help you more. Please let us know what you figure out.
