Greg,
If you can host these files for download, that would be great. STEP (.stp) files are solid, dumb models that can be imported into UG, ProE, Inventor, and other CAD programs. Thank you for hosting this and for asking.
Cory,
That is cool that yours went together without a hitch. It always worried me that people would find many errors. There were a couple in the documentation, but not too many in the models and details.
All,
I've talked to some people about this, but I have not said anything on these forums... and it is about time that I make an announcement:
Myself and another long-time TechnoKat engineer, Mark Koors, are creating a "side business" of making and selling standard mechanical assemblies. Our main focus will be to sell these assemblies, at reasonable prices, to FIRST teams. While we both still are working at Delphi, we are creating this company called
AndyMark. We plan on selling these standard assemblies initially:
- AM Shifter, a dual speed, shift-on-the-fly gearbox w/ 2.56:1 reduction, ready to mount 2 CIM motors
- AM Reducer, a 3:1 planetary reduction gearbox for Bosch drill or FP motors that mounts just like a CIM motor (can be mounted to the AM shifter)
- 8" Trick Wheel: simple omni-wheels with 1.25" plastic (or urethane as an option) rollers
Currently, we are getting quotes for fabrication and purchased parts. All of these designs have been proven in the past. The shifting gearbox and planetary gearbox were used on the TechnoKat robot in 2004, while the omni-wheel design has been around for a few years (although this is a simpler version).
Keep in mind that these will be "standard, off-the-shelf" assemblies. Our aim is to provide FIRST teams (and others) with a service while creating a business for ourselves. We are trying to use the advantage of buying and making parts in large quantities to keep costs down, but we have not determined our selling prices yet. Imagine buying one (or more) of these assemblies for almost the same amount of money it would take to make it, but you would have it during week 1 (or before).
Of course, we will be looking for customers. PM me if you are interested. We have a website in development (well, to be developed), and I will have marketing materials soon.
Andy B.
