SKI JUMP Profile



very creative. I like that guy with the yellow ski. But your speed calculation is wrong since the speed of the minifigure changes while it is between the sensors. But it should still be a good gues

wow do more do more

Probably, but if I had a longer ramp, the skier would eventually reach a terminal velocity.

Yes, that's true

have you seen my latest bot?you do not want to miss it :)and what is terminal velocity?

Yep, I checked it out, the biplane (or monoplane), right? And terminal velocity is where something reaches a constant speed because there is 0 acceleration because the forces of friction and propulsion are the equal. Orlando_2k was simply trying to say that the skier accelerates between the two light sensors.

streamliners:thanks for following me!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

yes thanks!and how do you program live sensor readings??


I don't think the skiers can reach terminal velocity until they are are not touching the ramp. Then they would be in complete free-fall, AKA terminal velocity.

Really sweet!!! A super clever idea! Congrats on the bronze streamliners!

Impressive! I must admit, I never saw this robot before now. I like how it calculates the speed, and especially like the minifigure stuck in the snow. :P Congrats on winning Bronze! :D

wee hee

I like it! Rating: ****

Wow! Is it possible to make a ramp?

The SKI-JUMP! is for making skiing more exciting in the Lego world. Before the SKI-JUMP! (in the first video clip) Lego skiing looked like a minifigure sliding down a slope and coming to a stop at the end. But now with the SKI-JUMP!, an RCX calculates their speed in SPS (Studs Per Second), and at the end, they are flung into the air, producing a variety of stunts (and I'm proud to say that in the very last clip, the minifigure does a full flip).
