If I were a judge (which actually might be quite likely in the spring; I’m not sure yet), the difference between on-screen CAD and on-paper CAD is minimal. However, what does matter to me is how much information you can communicate to me in the short time I have with you. If using the laptop slows down your presentation because you’re focused on getting the display right, or rotating something, or waiting for something to load, then cut the laptop and use carefully selected printouts.
Additionally, always have something to give the judge. If you can give me a printout of your CAD model with little callouts specifying “neat features,” that would be awesome.
A note about computers: the judges won’t have a computer. Never assume that they will have one to view your files. (Also, in general, if you’re ever giving a presentation to someone and want them to see a certain type of file, it’s probably best to assume their computer only has a PDF reader installed. Don’t assume the “average” person will have a copy of SolidWorks or Inventor installed.)
Nope. As a judge, I’d like to know why I should recommend you for an award. Most “reveal” videos are not geared towards this purpose, but rather designed for the target audience of potential alliance members. However, videos can be used to help explain some feature of your robot; for example, if you pick up game objects in a unique way (and, for some reason, cannot or do not want to demonstrate it in-person), it may be best to show a video of your robot picking up an object.
Summary: Basically, this all boils down to the purpose of judging: if I’m a judge, I want to know why I should recommend you. In preparing for judging sessions, you are seeking the most effective method of presentation to convince a judge that you are worthy of an award. So, for every point or item in your presentation to the judges, ask “what new information does this give the judge to encourage them to give me an award, and, is there a faster way to convey this?” Videos can help or hinder this, as can computer displays of CAD. Each case’s result is different, but the metric is the same.
