Algodoo

Очень хорошо.

Nice door and guide. Suggestions:
1. Reverse door motor so up arrow raises door.
2. Change collision group of back wall so car can't back through wall.
3. Use auto brake on car instead of toggle.

P.S. Maybe separate brake key (but no toggle) is better than auto brake for car.

Nicely done. Looks and functions well. Very user friendly.

Nice scene, but short explanation. What keys operate it? Do both mechanisms work together or do they both do the same thing? How does each mechanism work? What is the principle of operation? I know we can probably figure this out in time, but why not make it a little easier for us.

Does not work on version 1.8.5. Maybe needs Scene.my. variables. Also use change in time to calculate RPM so that it is accurate on all computers.

That might be the only place it works. If anybody else got this to work, then leave a comment.

Thanks. I appreciate the comment.

I got a low rating and was wondering why, then I noticed that my sim.frequency was set at 500 instead of the default (100). Works well at sim.frequency = 500, but kind of flaky at 100. May fix later but need to go to work now.

Tried a bunch of things to try and get this to work at sim.frequency = 100 in Algodoo v1.8.5, but not successful. Modified scene so user can press the "a" and "s" keys to change frequency to 500 and 100, respectively. Please let me know if scene does not work in Algodoo v1.8.5 with sim.frequency = 500. I am also interested in any ideas on how to modify the scene so it operates reliably at sim.frequency = 100.

Nice. Looks good and works well. Could be considered "Animated Art #11". I like how it looks going over the equally spaced bumps.

Great concepts. A few problems on my computer: Water hose holds, but does not pass water for me. "just try out" causes an Algodoo exception on my machine.

Excellent.

Instructions above are good. Text in pink box is missing last bracket. No onCollide script for ground. Scene does nothing. Will not rate.

Very nice. Water hose could probably also be used as a cable guide (like a bicycle brake cable). Setting Auto-Brake could stiffen hose if desired. There must be many more possibilities. I had thought that only one object and two hinges could be used for a chain. Thanks for showing me otherwise.

Very nice. How does it work?

Great idea, implementation, and explanation.

Works OK for me with sim.frequency = 500 but not at sim.frequency = 100.

Recommendation: Uncheck "motor" on wheel hinges and check "Auto-brake".

Thanks for listing your script in the description. Vehicle works well.

Nice demo and explanation.

@bozbez I agree, I see that you have a better ATV, and a flatter (faster) bridge. Other than that, our designs are essentially equivalent. I suspect you would have first place if the contest finished on the 7th.

Nicely Done.

Egg Salad (Excellent).

This is awesome. I do not understand why only rating of 5 with 3 ratings. I will help fix that.

Это является удивительным. Я не понимаю, почему только рейтинг из 5 с 3 оценок. Я помогу исправить.

@davidz, Stepper motor is now phunlet safe.

Interesting. At first glance, I thought this was just a variable torque motor, but now I see it is a variable torque slip clutch. Maybe this concept can be used to modulate the brakes on a wheeled vehicle.

@kamikaze6900 ,

Thanks for the feedback. The script is the same for forward and reverse. Works OK on my computer. I suspect the difference between forward and reverse operation is due to whether the braking wheel is the leading or trailing wheel. The leading wheel sees higher friction force upon braking.

P.S. Revised script for wider margin of operation.

Very creative approach, and since this is "the" solution, I guess there is no need to look at other solutions.

I concur with the statement above.

Nice golden arches. "Excuse me sir, would you like some fries with that?"

I like the fact that it takes up very little space, deploys quickly, has extra strong connections. and is flexible.
