| | | | | How true. But, to be fair, some 25 lb. things are easier to catch than others. What a silly little discussion this is! ;] (...) (25 years ago, 2-Jul-99, to lugnet.robotics)

| | | | | | Yeah, Except, I figured this one was going down entirely sarcastic lines of discussion. I mean, my sarcasm meter was pegging off the scale on these posts. However, I do think having it catch a 25 pound lump of feathers is a little trickier than a 25 (...) (25 years ago, 2-Jul-99, to lugnet.robotics)

| | | | | | Just having fun :) Thanks for the physics lesson. This is one of the aspects of robotics that I like; there are so many aspects that need to be taken into consideration.

| | | | | But *catching* 25 lbs of lead is different than catching 25 lbs of feathers. The G forces during impact (which in turn affect the forces needed to maintain balance) vary tremendously depending on the shape, size, and compressive properties of the (...)
