It's been one year since i broke it and 3 years since i first began this project while i was studying technical product design.
I couldn't design something without putting some exccentricity to it. I took some ideas from command & conquer and the front wheel design ist a copy from a Bimota Tesi but most people identified it as an abstract Batmobile replica.
I planned it to be a GPS controlled high speed rover for slightly uneven and urban terrain.
To finish the chassis i planned to add a rear wheel system with two wheels and a full enclosure. The drive test was successful and i just needed to decrease the backlash of the steering system and secure the rims of the front wheels from slipping out.
I used a 3660 brushless motor with a 2200mah nimh battery pack and a 60A brushless esc.
Anyway, it has been been a long time since i stopped this project but now i think it isn't good to let this project die unknown on my hard drive so i decided to share my files with you as some sort of a resource to use for your own projects.
I uploaded all the original source code, so you can modify anything you like with Autodesk Inventor (and maybe Fusion 360 but i need to reinstall it to test it).
At least i hope you like it and find it useful for something.
Don't fear to ask me something.
If you want to reconstruct it you need the following parts:
(I use metric dimensions (mm) )
-A heap of M3 x 20 screws (200 should be enough)
-Another heap of M3 nuts
-A hand full of M3 x 16 screws (50 or so)
-Some M3 x 25 screws for the front wheels and some parts of the frame. (20 or more)
-2 M4 screws for the suspension system
-At least 20 "61800" (10 x 19 x 5) sealed ball bearings
-At least 4 "61902" (15 x 28 x 7) sealed ball bearings
-2 "61911" (55 x 80 x 13) sealed ball bearing for the front wheels
-4 ball joints with m3 threads
-2 meters of m3 threaded rods
-4 M8 x 80 screws
-M6 x 20 screws (20 or mode)
-4 long M6 screws to reinforce the front wheel axles
-1-2 meters of Aluminium H profiles (need to check the files)
-1-2 meters of Aluminium L profiles (need to check the files)
-I need to check the files for more specific numbers and for something i maybe forgot
What the part code means (some parts are not categorized properly):
1xx : front wheels
2xx : front forks
3xx : chassis
4xx : front fork and chassis connectors
5xx , 6xx , 8xx : suspension and rear drive parts
7xx : rear fork and chassis connectors
9xx : additional parts and structural stabilizers
10xx : outer frame
RDR_xxx : headlight and (pathetic) ultrasonic sonar system
-The rods for the servo steering need to be cross connected to prevent disadvantegous relaive wheel angles.
-I printed the stressed fork parts (204 & 204_MIR) out of Taulman Bridge nylon first, but due to it's elasticity which had a bad impact on steering reliability, i then switched to PMMA for it's higher rigidity.
-It is possible to flip it on it's back when you accelerate too much while turning in a close curve.
