Algodoo

Lol whos lethalsquirl?

I am making a rotary version of this. Be prepared

I hate how this face ----> has really red cheeks. This is not what I look like when I make this face lol.

Because the hinges must be rotating for the engine to work. Its more of a "propellor" than an engine. The air friction of the piston is what makes it move. It needs to be turning when either the left or right arrows are pressed.

This is kinda like a bird wing. Higher air friction on the down stroke creates a moving force, and the wings have less resistance upwards so that force isnt lost.

Theyre supposed to be like spheres... Lol

Well, I couldnt find a way to actually cut it lol...

Lol there is another option for clouds within the scene coding.

If only things could be glued and unglued by scripting... That would make this easy. Just make the saw blade unglue the material.

Maybe I could mess with polygon surfaces, but again that would lag constantly. Someone mentioned about my grinding wheel scene to make the block concave where it gets cut, but that wouldnt be possible unless someone could make a polygon resurfacer script, which would consist of a series of small circles on the wheel, and when each one collides with the block to be cut, it sets the surface of the polygon to its center. But surfaces cannot be edited using script, so that will not be happening

Well, Lol i dont have skype, nor does my laptop have a webcam. Its one of those old ones that weighs 20 pounds, yet it runs Algodoo smoothly. I do not own an external webcam, but we could use the Algodoo forum message system, or even use text messages

The housing shape was rather easy. Ill post a tutorial on it.

I had to limit its power. The gears broke with my original spawn system, which had guides and ball deleters.

Well, I couldnt control the gluing... I actually intended not to glue it, but as I made the housing I noticed that pieces of it got stuck to the background and they didnt have a "Loosen" action. You could still make a spawn engine with it, but it can be stationary.

The gear on the Right end = Monday Morning!

I had it at 40 rad/s. I took the fuel pump gear and made it larger to get more fuel pressure.

My method can make any housing shape, including epitrochoids but also other radially generated shape. It also can make tracks for sliding mechanisms. This is more in-depth than my tutorial.

One thing: If you were to make 2 boxes, and put them on top of each other, and them add a fixate to connect them, when you try to add another fixate it just attaches the box on top to the background. It does not allow multiple fixates to make a "loop" with each other. Fixating two boxes together and then gluing them behaves like there are 2 fixates between the two boxes, making that bad loop where the glue then goes to the background instead of the box. Gluing works exactly like placing an invisible fixate.

This is an AIR engine, like I said in the description. If you actually read it you wouldnt be saying anything about spark plugs lol

I would think this could be useful in a high-precision grabber thing. The external housing would be fixed to an arm, and each of the rods would be attached to a finger of the gripper. Then, one of the fingers is attached to a cable to slightly move the hand left or right, so the arm does not require any high precision servo motors to measure angle.

This was Felix Wankel's original design. He was trying to make a compressor... But then he noticed that by adding another side to the rotor, the epitrochoid housing would need 3 lobes and it would be useable as a combustion engine.

The gears are too large to transmit full power, they lose sync and skip teeth.

I couldnt make this with an odd number of cylinders... The linkage I used only works with 4 cylinders. Using the rhomboidal linkage, I was able to get away with having only two connecting rods.

This was originally going to be a cam engine, but once I made the cam, I noticed that Algodoo had a hard time calculating the collisions at such a high velocity plus, it was almost impossible to make a reliable timer.

This is just a collision engine... Lol. I will make a few radials though, but they will still be colliders. Im not ready to make multi-cylinder fuel engines yet XD

Yeah but adding the counterweight made it more stable. Also, your use of the term "vibrate" is incorrect, as a true vibration would be a reciprocating motion, rather then a circular motion as here. Vibrations are waves in velocity. Here, the housing would "rock" at a constant velocity in changing directions.

Rotary engines lack reciprocating parts and therefore do not truly vibrate, but more of a circular motion. Vibration is a reciprocating movement.

The size was because of the C-gears I used... I couldnt find a way to scale them down properly so I just used them at full size. Plus, I didnt need an epitrochoid generator to ake the housing. It was just two circles connected by a box.

Yeah, scaling down the size also scales down the densities and masses.

Exhaust gas DOES escape frequently, I just noticed. The way the exhaust system woks is just by collision layers and velocity scripting, which most often leads to gas prticles being forced through a wall or something...
