We make 100% of all our CNC milled parts on a ProtoTrak. We have absolutely no problems cutting any kind of aluminum. What sort of problems are you having?


Also, about the tensioning system...it seems extremely similar to 254s, why are you keeping it secret?

Its the programming of pocketing that is hard, not the actual cutting.

Well its the way the cams are turned, not the actual system.

Re: pic: 2011 Drive Prototype
 

What CAM package are you using?

Re: pic: 2011 Drive Prototype
 

This looks to me like a redrawing of a 254/968 robot. WHile good for developing CAD skills, it is only probably 10% of the actual design process. The secrecy about the cam is particularly bizarre. I can't imagine anything you have done to drastically change the already mentioned cam method of tensioning that you wouldn't even know about without the free sharing that 254/968 participate in.

It's a bit disheartening to see all this "design" and "prototype" being claimed as your own, when it is clearly a near carbon copy of an already existing design although not even the most recent version of the drivetrain that they use.

I am a bit worried about the amount of people posting "west coast" drive "designs" lately that clearly dont understand the actual intricacies involved with the design and instead of taking the time to figure out the chain runs, bearing blocks, tensioning, etc, spend the time focusing on making "cool" renders. When it comes to how the robot functions, the quality of the render will have absolutely no correlation.

Sir in no way is this a copy of 254's robots, it may look similar as a lot of robots made of 2x1 and 1x1 do. but all the dimensions and shapes are way different than 254's. The person that showed me how to make a cam isn't even from 254. Also, i did spend time mapping the chain runs and making sure the bearing blocks worked correctly. And anyways the render took me 5 min to make and less time to setup, the only reason i put a render up is so that there weren't a whole bunch of black lines and little colors.

Re: pic: 2011 Drive Prototype
 

The machines cam is an old style acer not sure how to describe it, but you plug numbers into the machine and it goes to those points.

Re: pic: 2011 Drive Prototype
 

Well cmon then!! Your machine is more than capable of doing it, so why sell yourself short?? Just about any CAM system will allow you to program the pockets with relative ease.

Re: pic: 2011 Drive Prototype
 

i guess that its not really worth the time, but i will think about it

Re: pic: 2011 Drive Prototype
 

Neither is making aluminum gears ;)

If you don't feel it's worth the time and effort it takes to put some pockets in a gearbox plate, I really don't think you're going to want to go to the extreme level of effort it takes to make that happen.

Re: pic: 2011 Drive Prototype
 

This is true... i guess we will buy the gears from AM then put them on weightwatchers. ;)

Also can you or Nick Eyre please show me how to pocket the plates like 254 does it Cory? because the only pocketing that i know how to do is by cutting triangles.

nice chassis, i like it

Re: pic: 2011 Drive Prototype
 

Just wondering, by any chance were RC or Eugene Fang helping you out with this?

Re: pic: 2011 Drive Prototype
 

Eugene explained what WCD was and RC explained how the cam lock tensioning system worked... Oh yeah and RC told me how much my renders sucked haha.

Re: pic: 2011 Drive Prototype
 

To deny this is a copy of 254's (and 60's and so on) design is simply disrespectful.

There is nothing wrong with copying someones design and using them for inspiration; It's only wrong to deny it.

Re: pic: 2011 Drive Prototype
 

I meant that it is not a "Carbon Copy" as he called it, it is a copy of the concept but not the total design.
