You have discovered Dale Heatherington's channel. His robot-related website is: http://www.wa4dsy.com/robot/home

Fantastic resource, I'd say he has lead the way in designing and building various exotic weapon types.

So I just wanted to clarify a few things for Trident.

First: someone suggested to me that we use a 12V drill innstead of a 18V drill, I don't know how or why this would be a good idea, so were stuck between a hard place and the Rock on what to use, if anyone out there would like to tell me what to go for, that would be superb.

Second: We don't know what we should use to power our weapons, we have chosen 3 options: Springs, Co2 and batterries, all of them have their advantages and disadvantages, but, what is the best?

Third: We don't know if we could make the weapons interchangeable for certain times and needs or to just keep the 1 set and change them when they are damaged, if anyone can tell us what the best waay to go, we would thank you.

Finally: We don't know if our robot would be large enough to fit everything in, we want to be able to flip the house robots Oll-E and Matilda and have the capability with 3 spikes sharing the weight, but the big problem is space, we don't want it to be too large but not to be too small, my cardboard model didn't work out as I planned as I don't know the relevant dimensions for anything apart from the body, so if anyone could give me the max height length and width a fetherweight could be, would be superb.

Thanks for the support
Many thanks
