Algodoo

Xray -- I had also made one with just a cicle and axle. The circle used the following script: angle = Scene.my.atan2(pos(1), pos(0)). In this case the pointed end of the circle cake always pointed towards zero. The function, Scene.my.atan2(), can be found in this scene.

I would like to take credit for that, but I got the Atan2 function definition from Wikipedia.

Well done. Nice graphics.

Yes, this beats my new bot. As far as "any other stuff", that is something that only Algobot5000 knows, and I think we should just disregard. So I accept defeat, for now...

I have revised my original Contest Ender Ender scene to handle your negative attraction bot. Looks like you better try a little harder next time.

Works well. I don't see why anybody would downrate this.

I disagree. You should move my bot straight down so that the wheels touch the surface of the gold block. In that case it is a draw since the projectile is deflected without knocking my bot off. However, my (3,289 kg) bot is then unable to push your (1,789,673 kg) bot off the side. Try again.

I agree with animator13.

Very cool. Is this your idea, or did you see it somewhere else? How did you make the wheel? Did you use a laser cutter to shape the wheel?

Nicely done.

Nice scene, but I have the following suggestions:

1. Add a parking brake indicator.
2. Use a different key other than "shift" for charging. Windows users may get a "sticky keys" message if shift is held down too long.
3. Make the car bidirectional. This may be difficult, but when I blow by the charging station I can't seem to back up and end up dragging the car to the charging station.

This is very good scene even without the suggested changes. I will probably rate it highly within the next week regardless of if the changes are made or not.

Good idea.

I just modified the bot in my original scene to be just a little harder for you to defeat. You may as well just give up now rather than waste your time trying to defeat it.

I made it because Xray mentioned that he would like to see it work with BOTH wheels being an odd shape. Improving something you made is easier said than done. I tried replacing your stretched hinge drive with a sprocket and chain but the chain did not behave well.

Interesting. I looked for spinthariscope on YouTube and your simulation looks believable. I don't know much about radiation, but a spinthariscope doesn't seem like a very safe toy.

I suspect that is much less than the radiation from the vacuum tube diode in the high voltage section of an old television set.

Very good. The more I play with it, the more I like it. I like how you can do very controlled wheelies after charging.

I was just trash talking. I didn't expect you to give up. Well, you can always try again later.

#1 damps the collision the most, is the least effective, and absorbs the least energy.
#2 is the most effective, and absorbs the most energy.
#3 damps the collision the least, is almost as effective as #2, and absorbs slightly less energy than #2.

I judged effectiveness based on maximum deceleration value. The lower the value, the less trauma to the car occupants, the higher the effectiveness.

I measured the energy absorbed by plotting the energy for the dampers.

I judged the damping by the total travel of the cars after impact. The greater the travel, the lower the damping.

Nicely done. Good demo of something we can try in real life.

Elegant

I rated the scene highly because it is done very well. However, I am opposed to the lottery because it unfairly extracts money from people who, often times, can least afford it. I suggest Algodoo users pick some numbers and then play this Powerball until they hit the jackpot. Here is an interesting presentation of Powerball Odds. Be sure to read the 2nd and 3rd thoughts at the end of Powerball Odds.

P.S: Be sure to send Xray half of the money you save by playing this Powerball as opposed to the real Powerball.

My expectation, that this scene was probably good, was true.

I'll rate this highly also. I assume this is an original idea. Well done.

I agree with Kilinich. I found myself laughing as things melted and got sucked up. Awesome effect.

Great workmanship and visual effect. Best Zippo I've seen so far.

Yes, much easier with max drag force = 400.

Another way to show this is to attach a small circle with a tracer on the tire. You can then plot the speed of the small circle. The tracer will show the path and the plot will show the speed of one small element of the wheel.

I agree, your scene stands well on its own without any added info.

Thanks.
