Re: How much planning goes into your robot?
We work with NASA programmers, engineers, and machinists out at the KSC Prototype Lab, so even though our students do a lot of the calculations and drafting, i'd consider them both to be at the Extreme level.
Roccobot is completely designed from top to bottom and everything inbetween in a program called Pro-Engineering, or Pro-E for short. (its kind of like CADD for those of you who know what that is... essentially, we build a complete three-dimensional model to an extremely accurate scale on this program before we even think of going to the machine shop) We know exactly how the robot looks and pretty much how it will work before we even think of taking a sheet of aluminum to the watercutter. Just because we arent allowed to use the machinery out at NASA (due to liability issues) does not mean that our mentors build our robots for us. Although techinically they machine each unique part for us, we students are the ones who work on Pro-E and actually design the robot first. Then a mentor will look over what we've done, and together both the students and mentors will work to achieve perfection. If we machine something and it doesnt work, we go back to the drawing board and try again, but our goal is to never have to do something all over again. [Six weeks is not long enough, and we do not want to waste time by having to rework calculations just because something was off by five millimeters. We want to ensure that we conserve as much time as possible, so that our drivers can at least get a little practice time in before we ship the robot.] After each part is made, the members of our pit crew actually assemble to robot themselves, with very little if any aid from mentors, only using the Pro-E blueprints that we've printed out. This way, everyone on the pit crew knows exactly what goes where and how it all works, just in case something stops functioning after a match. It's a lot of work, but its worth it. ![]() |

Going into the 4th week we are still planning things and trying to cooperate with our one sponsoir that dropped us and wont make parts, and one company that said they could make our parts is not going to be able to. So I think we are about at the standar time we are usually at. Not being able to start working on the robot till the staart of the fourth week.

Re: How much planning goes into your robot?
This year, 45 had like 4 or 5 sub-groups. They all stayed apart for a week and we presented a prototype made of like cardboard at the end of the first week. Then, Andy combined all of em' into one basically, he also added his own ideas in. This year that method worked out really great for us.

We do split into 4 different design teams for 5 days. At the end of this time, we get together and each team presents their concept and how to play the game. We highlight the ideas we, as a team, like the most. Then, we sleep on these ideas for a day. The next day, we get together and choose an overall design, as a team. We took one design team's idea (Austin and Steve Butler's group), and then added a "funnel" idea from the group I was on. We knew that if the funnel design did not work, the fall-back plan was a ball-collecting robot with a great arm. (it was definitely not my idea... it was a team decision this year) Andy B. |

Re: How much planning goes into your robot?
We do everything for our robot from the second kickoff ends to the final day of shipoff's
![]() And we do it moderately-extremely (no inbetween, all well). |

Re: How much planning goes into your robot?
We also split up into design sub-groups for about a week after kickoff. About a week and a half in, we present prototypes to the combined group, make adjustments to calculations for a few days after that so that each part fits. We attempt to CAD it out, but most times we just have really specific drawings on paper of each system. Then build begins (trumpets sounding in the background)!

Re: How much planning goes into your robot?
Our team drafts and calculates everything to the smallest hole. It is definitely why our robots are usually good every year. Even if we make design changes, or anything, we CAD draw it first, do the calculations and then make changes. The main people behind this is our Bristol Myers tradesmen, we learn a huge load from them. They are truly unique people.

Re: How much planning goes into your robot?
Is there a book/web site/white paper that you know of that discusses in more detail on how "eventually you'll end up with a differential equation", something that I can use to explain these complex calculations in lame terms for my team?
Thanks Adrian |

Re: How much planning goes into your robot?
I would say we've done a great deal of drawings for arm design concepts. Some have tentative measurements some have none and some are competely to scale.
As for calculations they exist to make us change our arm design. Our design process has gone something like this: Draw a concept design of the arm Redraw it with angle and length measurements calculate torque etc. redesign arm repeat |

Re: How much planning goes into your robot?
We're 3 weeks in... and still designing! They say we'll finish CADing tonight...
probibly... hopefully... maybe?... Ah screw it, it ain't happening! ![]() |
