Hi Machina,
I do not know your skills, but I think this robot is not a “start here” project. Anyhow I have attached the 3-D-sketchup model of my robot. This should be more useful than any describtion. If you don’t have sketchup, just download it, it is freeware. You can watch the robot from all sides, disassemble it, measure etc.
Personally I know if i
Personally I know if i documented exactly how to make every one of my project how I did it then I would have no time to make projects.
There is a tutorial section and if something is posted in there then it is expected for it to be well documented, but I think the general construction, photos, and pictures suffices as a good robot page. Not every one will learn from what you did, but some times we do not have the time to be constantly teaching.
Build robots and have fun doing it, anything more than that is just gravy.
a question
For some reasons I felt the joint in between servos seems weak to carry the heavier weight, and it might cause the servo above the wheel have sorta contact with the wheel??
over all I love this bot, nice concept~
Not weak at all:)The picture
Not weak at all:)
The picture below shows the construction. The part which carry the weight is made from 2 mm epoxy sheet. Epoxy sheets can carry a lot of weight and it is also a little bit flexible, so it acts on every wheel as a kind of little shock absorber.
Can you please
Can you please tell me where you got the 3-d sketchup download. I want to make a desighn for one of my robots with it.
Hi MarkusB
Great Bot !
Can’t wait for video. Great documentation too. You even texture and paint your sketchups. I have heard of the rocker-bogie suspension, but never saw it. Facinating.
On another note, your robots are extremely well crafted with the a great diversity of material (steel, epoxy sheet, wood, aluminum, etc). If i remember correctly you work at a university in China. Do you put together your projects in the university shops? What tools and machines do you use the most? Could you show us some pictures perhaps?

That’s cool~ I haven’t use
That’s cool~ I haven’t use epoxy before. Is it strong enough to hold different material? Personally I love to use servo to do precise movement. Love to see it in action. This bot reminds me the one I saw in http://robots.taobao.com/

Hi GroG,
I work with a Chinese university in my free time for the Google Lunar X Prize.
The robot was built in my workshop/lab at home. I do not have too much tools, a small battery drill, a metal saw, a Dremel clone, some files, that’s it. I like to use materials witch I have already and to improvise. The bearrings and joints I used for this robot for example are from a rollerblade 
Maybe fiberglas is a better
Maybe fiberglas is a better describtion than epoxy sheet. Fiberglass is very sturdy but it can be easily machined with a Dremel or metal saw.
I saw this robot on taobao too. I love taobao, nearly daily I am ordering something for my robots.

You mentioned in the Shout Box that you were thinking of building a 3 wheel rocker bogie. Do you mean that the entire vehicle will have three wheels, or that each bogie will have three wheels?

I mean that the entire vehicle will have three wheels, but it’s just an idea…
**Nice idea on the **
Very nice approach to the obstacle avoidance. I might redo mine now that I’ve read your idea.
Cool. Be sure to make a new
Cool. Be sure to make a new video and show how it works

Speaking of videos, when are we going to see this beast in action, Markus? ; j
Programmed a show case
Programmed a show case (showing the diffrent moving functions) and obstacle avoidance mode already the last 2 nights. Yesterday it climbed over a 8cm high obstacle (hot chocolate box). Unfortunately I need to work tomorrow (Saturday, damn it), so I’ll try to shot a video on Sunday
Bigger wheels
You might want to consider bigger wheels.

"Do the Hokey Pokey".
SWEEEET!!!
I am so exciting to see it in action!! What a cool little guy~ Looking forward to see more of it~~
