To lift up <em>vertically</em>, you will need to use Force=mass x gravity.<br />For 40kg, a force greater then 392N is required.<br /><br />You build robots and you don't know how to calculate force?? Wow....<br />

Lots of people build things and don't know the numbers.  They have very good intuition.  And they don't stop at the first failure.

Wish I had learned a few more of the numbers when I was younger!

Since you want to THROW it in the air, its not that simple to work out. You need to accelerate it to some speed. How high ? How long in time and distance have you got to accelerate it ?

 about 2 to 3 feet is sufficient dude:)...just to scoop the opponent and launch it in air so that it would topple.
