Hello fellow EZ-B'rs, As I finally discovery how to upload photos I thought it was time to share my robot with the world. It's called R.O.O.S.T.E.R which stands for: Remote Online Operating Scientific Testing Electronic Robot (took me about an hour to come up with that, but I like it).
The specs:
- 6x 6v 6A motors
- 2x 20A Rc Car ESCs
- 2x Reddragon 2s 25c 1200mAh
- Ofc the Ez- B
- Dfrobot 5dof robotic arm
- Asus Eee pc 900hd
- Ping sensor (well... I sort of broke it... It got stuck between the robot and the wall...)
Why I'm building it? Because I can, robots are Awsome, the EZ-B rules and I got tired of burning/shocking myself when I'm testing one of my "crazy" contraptions.
Up coming updates for robot:
- A rotationplatform for the arm.
- 2 gigantic lipo batteries.
- camera+ pan/tilt turret.
- Small rockets
- mini mini-gun
- Flamethrowler (a failed version of a liquid fueled rocket, but it's working if you call it something else)
- coilgun
- railgun
- Lots of other things I can come up with.

Lumpy's Lumpy's - R2-D2 Build Two-Two's
Hello Again, Ive been asked to post some pics of my R2 build. Ill toss them up. This has been approx. a 3 year project...
Small update:
I've made a design based on the axles that came with the RC cars, so I figured to recreate them, but then shorter and made of steel. The plan was to make them myself, I have a lathe so I figured, I can do that!
But after about 6 hours working the lathe I had enough of it, it took forever, so I had them CNC'd by my brother. It's just insane how fast those machines work... It took me over 4 hours to adjust the diameter of one axle from 10 mm to 6 mm over a length of 70 mm with steps of 0.2 mm at a time. And it had to be done manually... But doing it with CNC lathe took only 30 minutes per axle ... And then the axle was actually finished, complete with everything, it would even be polished... Lets just say I was sort of baffled when I saw the result, it just looked amazing. With the polished finish it looks like there is another world inside.
They are so shiny:
I know it's a "little" dark but I was so excited to share this, that I couldn't wait until tomorrow.To be continued
love this project so far! like the idea of adding shocks and multi steering axles.
Why couldn't I think of that! hits head on desk
@Technopro Ah thanks man, I appreciate it. I got the idea from the MindSI 6wd robot, but when I saw the price tag I thought, I can do that, maybe even better and atleast for way less money.
Today is tomorrow, so here's a better picture:
They still are so shiny
Another micro update: My axles are finnaly finished. The pins in the end pieces weren't added yet, but now they are so this means they can be installed. And therefore I'm giving a headsup for a testvideo. I will probably make one at the end of the week(friday/saturday), if everything goes well. I've already tested the motors in combination with my dual output differential, so I'm not expecting any resistance. (Personal Note: my god this thing can go fast, expected speed: "35+ km/h" )
In the upcoming test I will only be testing the "Suspension Upgrade" no EZ-b involved yet. I haven't made the parts yet that connect the old robotparts to the "Upgrade".
Plans for the very near future:
As promised, a video of the upgrade:
First Test

Great! I like ROOSTER. It's a very cool concept.
crap, i don't even have my current thumper up and running the way i want and now i want to copy ROOSTER
Aw man, that's so awesome! Are you a mechanical engineering student?
