Round Tubing Construction
I'm interested in some of the robot designs that revolve around bent round tubing. Primarily 1024's usage of this unique build style. I have several questions (if someone from 1024 could address these it would be great):
1) What is the tubing? I assume it is 1 in OD x .065 wall aluminum or similar.
2) What do you use to form it? Is it a rolling machine of some sort? Or just a simple conduit bender?
3) What are the fittings you use to join the tubing and where do you get them? They aren't very recognizable from pictures. Are they clamp on, press fit, etc.?
4) What kind of tolerances are you able to hold on bend angles and such? I can see getting OAL and bend offsets right being very difficult.
5) Would you recommend this build style to other teams? What advantages do you see it having over more traditional methods (sheet metal, extrusion, box tubing, etc.)?
6) Are there any CAD models available that I can mess around with for more details?
If someone who has experience with this build style can shed some light on this it would be greatly appreciated.
