After a request from Bigisezhi I made this tutorial outlining how to build a fully controllable car using google sketchup 7 and the free plugin sketchyphysics 3.
Big I is very very happy with what he is seeing here in what has to be THE BEST, MOST ACTUALLY USABLE in the real world Sketchyphysics TUT I have laid these big eyes upon until NOW! Most others on You Tube just race through procedures never explained, or given context, much less even adequately visualized! I for one am grabbing this TUT, and disappearing to Sketchyland for who knows how long, until I master this system! YES! Thank you for all your hard work, it's all up there, plain as day! :D
I wholeheartedly agree with Big I. This is a clean, well produced tute for the car anims in SP. For those of us who read, like clear details, and don't sub just because a ten year old asked them to; this is a great tutorial!
Seperate the front servos and rear motors from the main body. Group the front turning servos and rear motors to two separate blocks in the position of axles. Onto these connect springs, one at each side and then group these with the main body. This should give you some basic, non-independent suspension. Hope this helps.
You should ensure that the wheels are not grouped to any components but must be acted on by the hinges grouped to the white boxes. The boxes and hinges must be grouped and acted upon by servos which in turn are grouped with the car. Hope this helps.
@bagas2803 The left motor and servo are created in the same way as the ones on the right, but the direction of the motor is opposite. You must therefore swap the min/max values when entering the numbers for velocity. The servo is exactly the same.
@MrKicker98 In the motor properties box, make the first number "maxAccel" larger. For example, it the number is currently 10, making it 100 will make the wheel rotate ten times faster.
@Monty228CZ You were correct by adding motors instead of hinges, but the motors must have the same settings as the rear motors or they will just function as joints. Hope this helps.
Thank you for your feedback. I would like to clarify that I refer to the car being "fully controllable" rather than the construction of the car being "fully explained". As a result, I make no mention of how to build the bodywork mesh of the vehicle and instead focus on the mechanics of the simulation. As a result I feel my description is appropriate.
@mixerinc If you set the body to a rectangle, then the rectangular mass pushes all objects within in outwards, including the wheels. What you need to do is set the body of the car to ignore. This means that collisions may be less realistic, but the wheels will remain in place and the car will function as you'd expect. Hope this helps.
This really is the best tutorial going for this setup - thank you. I have a question - I just used a solid rectangle for the body and grouped it to the wheel hinges and rear motors but the front is very sloppy. Wheels actually collapse outward and seem to not be able to handle weight - can you give some tips and upload some more walkthroughs of the other components such as springs etc. Thanks
If you wish to make it four wheel drive, you must make the joints on the front wheels motors. These motors must have the same acceleration and damping values as those operating the rear wheels. It sounds as though you have perhaps altered the values slightly and made the front wheels turn too fast. If they wobble too, then it may be that the joints are not centered correctly which is made more obvious when power is applied. Finally, ensure all the wheels are set to chamfers. I hope this helps.
@devlincr1s32 It may be that the wheels are not set to the correct shape. Just right click on each of the wheels select SketchyPhysics, then shape and then choose either sphere or chamfer (sphere is usually best) and that should sort the problem. Hope this helps
Make sure the joints are all grouped with the main car body and that there are no sub-groups containing bodywork within this. Failing that try re-connecting joints and their respective components. Hope this helps.
This sounds like a know bug with SP3.2. When you open sketchup and first use the UI menu, make sure you don't close it or it will crash and just show up blank, ensure you only minimise the menu and it should work. With regards to the wheels, make sure you connect the joints to the wheels before you group the joints and the bodywork, this may solve the issue. Hope this helps.
@GoodwoodRRClub thanks for the fast answer. i fixed the problem. try to get an older version. and trying to get that i found an article on google. my mistake was to close the UI after entering the text. just klick on UI again when your finished instead of closing it. i hope my english is ok xD
Thanks for your quick reply. Because of my basic editing skills I have added subtitles to the video post-production using UA-cam. Is it possible that these have been disabled by a certain browser or ad-blocking plugin? In which case the tutorial contains no explanation and would be thoroughly useless! However, there is no way of comprehensively explaining how TO build a fully controllable car without demonstrating the building of such a car. This video is as mentioned, just an amateur outline.
@GoodwoodRRClub But i had same setting as in tutorial. I dont know... when i play animation, front wheels fallen out and car was lying at chassis. What i must connect with motor, box, servo? but thank you for Your quick answer :)
great tutorial the only thing i dont figure out yet is the SketchyPhysicsInspector. UI it works fine the first time but then when i klick on the other motor or servo it just show the words, Joints , State, Propertie, Shape... but i can not type anything in?! need help
How do u make the wheels turn at the same time, whenever I try to do it, I have two different controls for each wheel to turn, I want to try to merge it so I have one turning control to turn both front tyres
great tutorial, but how I do Front wheel drive. I tried change hinge in front as motor, but it doesn¨t work. Please help me! I tried it five times and every bad. sorry for my english
@TheMegaYUtub I had the same problem too, I think it may just be a bug with a certain version of SP (maybe 3.1?) I just re-downloaded the latest version and it seems to have fixed the problem. (You could try a slightly older version if it still doesn't work) Hope this helps!
thanks,great vid,but i did everything you said,but the car just "blew up" and rotate 180(lol),i have try to group every part of the car but it won't move,help please
This is a bug that is well known, just make sure after you edit the first joint you don't close the UI, minimise it instead and it should work fine! Hope this helps
i did this and when i clicked play animation, everything fell apart, I used the Bugatti Veyron Super Sport. I have Google Sketchup 8 with Sketchy Physics 3.2. Please help
Please help. I'm trying to prove to a friend that a ball orbiting inside of a funnel will orbit forever, if there is no friction. Can you do a quick simulation for me? Thanks!
+Rostislav Persion Possibly, although as far as I know, the surface friction of meshes in sketchyphysics is quite high. I've not used the software in a long time so it's possible there has been an update allowing this to be adjusted but in the version used for this video I don't think it could be done.
+Nicholas Lette van Oostvoorne Can i ask one more question, i made chain and it not hold together parts simply crumble and fall down. why ? all are groups of course
i have followed this tutorial from step to step but my front wheels falls of the car O.o when i turn, the white boxes in the front wheel area moves but thats about it... when i tried to group the front wheels with the car the whole car falled in pieces. i used the car you used in this video but still no luck. i use Sketchup 8 with sketchyphysics 3.1
Yes, you refer to the car being "fully controllable" but it's the part that comes right before that where you wrote "I made this tutorial outlining how to build a..." Do you see that? This is a demonstration of how YOU built a fully controllable car. This is not a tutorial on how TO build a fully controllable car.
Your discription is misleading. It says "...how to build a fully controllable car using google sketchup". But, it doesn't show how to build ANYTHING "partically" much less "fully".

THAT WAS THE LONGEST BURNOUT I HAVE EVER SEEN!!!!!!!!

Thank you very much! Now it works! :)

@MrKicker98 I press down shift to keep the body of the car selected whilst I deselect the wheels. Hope this helps!
@GoodwoodRRClub Yes i do it. I have fwd. Thank you very much for this great tutorial. It was my dream, construct 3d of car i designed and drive it :)
@devlincr1s32 It may be that the wheels are not set to the correct shape. Just right click on each of the wheels select SketchyPhysics, then shape and then choose either sphere or chamfer (sphere is usually best) and that should sort the problem. Hope this helps
Make sure the joints are all grouped with the main car body and that there are no sub-groups containing bodywork within this. Failing that try re-connecting joints and their respective components. Hope this helps.
the model is available online on the google 3d warehouse.
el modelo está disponible en línea en la Galería 3D de Google.

I agree but at the time I made the video, I didn't have a microphone or webcam etc to record any form of narration.

@16989473 Make sure that the ground geometry is a group and that it is set to 'staticmesh' in the sketchyphysics menu, hope this helps.
Thanx ^^
@GoodwoodRRClub But i had same setting as in tutorial. I dont know... when i play animation, front wheels fallen out and car was lying at chassis. What i must connect with motor, box, servo? but thank you for Your quick answer :)
how do you ensure that a hinge rotates with the engine that something that the hinge is still moving?
@GoodwoodRRClub thx sorry 4 the silly question im still new to this
can u give a link to ajust the controlles of a servo hinge enz
great tutorial the only thing i dont figure out yet is the SketchyPhysicsInspector. UI
it works fine the first time but then when i klick on the other motor or servo it just show the words, Joints , State, Propertie, Shape... but i can not type anything in?! need help
How do u make the wheels turn at the same time, whenever I try to do it, I have two different controls for each wheel to turn, I want to try to merge it so I have one turning control to turn both front tyres
great tutorial, but how I do Front wheel drive. I tried change hinge in front as motor, but it doesn¨t work. Please help me! I tried it five times and every bad. sorry for my english

I think so, although I'm still using sketchup 7 so I cannot speak from experience.
Thank you. Problem. The wheels are being thrown out. Help. Please.
I am trying to move a car up a steep slope but it won't move. can anyone tell me why and what the motor settings should be for the rear wheels.
Hello my friend!
Please, I can not turn the front wheel vehicle. What is going on?
does it work with the new skechup too?
Buen aporte, podrías subir el auto que usas en el modelo?
Gracias!!!
thanks,great vid,but i did everything you said,but the car just "blew up" and rotate 180(lol),i have try to group every part of the car but it won't move,help please
This is a bug that is well known, just make sure after you edit the first joint you don't close the UI, minimise it instead and it should work fine! Hope this helps
cool
what do you press at 0:45
hmm.. I can edit the UI only of one joint.
If I try to edit a second joint it doesn't works anymore. :(
where do you get sketchyphysics from?
@mzshangopang If you let me know what parts don't work then I'll try to help you.
could u give me a list of UI commands plz
i did this and when i clicked play animation, everything fell apart, I used the Bugatti Veyron Super Sport. I have Google Sketchup 8 with Sketchy Physics 3.2. Please help
how to make the car faster
Please help. I'm trying to prove to a friend that a ball orbiting inside of a funnel will orbit forever, if there is no friction. Can you do a quick simulation for me? Thanks!

Hey can i ask how to change direction of motor ? cahnge direction of rotating
+Samuel Bachorik If you want to change the direction of rotation, swap the minus sign from one motor to the other. I hope this helps.
+Nicholas Lette van Oostvoorne Can i ask one more question, i made chain and it not hold together parts simply crumble and fall down. why ? all are groups of course
when i do it, the car just sinks into the ground
i have followed this tutorial from step to step but my front wheels falls of the car O.o when i turn, the white boxes in the front wheel area moves but thats about it... when i tried to group the front wheels with the car the whole car falled in pieces. i used the car you used in this video but still no luck. i use Sketchup 8 with sketchyphysics 3.1
The problem is, you need a square flat on the bottom of the car so it will not fall
Please give me this for my car contest. Thank you!
in my case the wheels collide with the body.....
I'm happy 5*
O.o i don't have play animation tolbar for some reason but other are ok o.O
