well i have personnally already given talks to my school mates with typhoon 2 sitting at the front of the class

true it was mostly about the robot and how strong things were etc however it did give them an insight into the robot.

Its really not that hard, if you can go on national tv with your robot then a room full of people should be easy (thats my way of looking at it)

I agree that a classroom type environment is the best place for people to actually take in what is being said as there are no distractions. How about it being on the last day of competition at an event (should it go over a few days), in the evening so that the interested parties have seen the robots in action and then they get to see what makes em work and how things are put together?

what about having a smallish room with chairs set up in a semi circle around the robot, the speaker gives a quick run around the robot and then anyone can then ask questions about how certain things were done etc? this could probably accomodate around 15 people max if it was to be worthwhile.

sorry im just giving random ideas as they come into my head (it might not be so good to post just after 2 hours of rugby training, but there you go)
