Considering where you drew your inspiration from, I am not surprised that this design turned out so beautiful! I really like this and will definitely ask my students to consider using something very similar, if the game lends it's self to this design. Again, based on the game, I might suggest some mods, but over all, this looks extremely well thought out. |
Re: pic: 2 Weeks Without Homework
Overall, very nice! Looks solid and efficient.
One quick question: How do you tension the drive chains? Sliding blocks like 254/968? Keep up the good work! |
Re: pic: 2 Weeks Without Homework
Looks very nice! You put a lot of thought into this. It turned out very well. :D
Few questions. Whats the weight? Is that plexi-glass that the electronics are mounted on? What type of gearbox? (Sorry, I can't really tell from the picture.) Overall, I love it. :D -Rion |
Re: pic: 2 Weeks Without Homework
I have to say I like the nice clean bumper mount rails with the cantelievered wheels. the AndyMark hex bearings make this a super simple design to build eliminating any need to turn the Hex shafts if you plan it right.

Thanks for the input and comments.

The electronics are mounted on a thin plexi layered on thin aluminium sheet metal (which is not visible). The reason for this was mostly electrical isolation for the control system. The gearboxes are modified AM Supershifters with the black covers removed, standoffs installed, and a custom long output shaft to interface with the AM performance wheels. Quote:

Re: pic: 2 Weeks Without Homework
Nice CAD! Why are the gearboxes turned 90-degrees from each other?

But it isn't to reverse the direction of the wheels without programming. He'd have one gearbox out over the bumper area with both pointing the same direction if that was the goal. |

Just a theory. -Rion EDIT: I forgot about what Mr. Anderson said, he is right, I designed a chassis with these over the summer, I did the same thing. EDIT2: Scratch that. They are both pneumatics. I would delete this.. but I can't find how. :D |
Re: pic: 2 Weeks Without Homework
Woot, cool to see a more completed design than what RC and I have been talking about.
http://picasaweb.google.com/rcthekid...03106851444610 I love the use of the rivets as our team has been looking at similar designs due to lack of trained welders. Great stuff! Hope you actually get to use it this year though. |
Re: pic: 2 Weeks Without Homework
The gearboxes were placed in the way they are for space savings, and to shift the CG to the rear (I assumed the robot would run mostly on its rear wheels, the gearboxes could easily flip for a front-heavy robot). The other reasoning for this is that I wasn't sure how the AM SS kit shipped, so in this design, no matter which way the gearbox is assembled, it still works (You only need one spare gearbox). They are both pneumatic, as this seems to be what AndyMark recommends.

Re: pic: 2 Weeks Without Homework
Wow, this looks really intense. Its my first year on my robotics team and i can't wait to see what competition is like! This is very thought out and looks great! keep up the good work!
