Thread: How to build a combat robot guide.

Had a quick read through, and it seems pretty ace. Considering its for use in schools (or at least to teachers), a few notes;

Perhaps add M.R. Speed Squared as the demo bot for the full body spinner on page 5, this will be a more known robot to kids than Ringmaster, I don't believe that bot ever competed to any notable degree here in the UK. If you're wanting teachers to grab the attention of children with demos for possible designs they can do (if the teacher is going to give a choice) then I think M.R. Speed Squared will probably work better, as they'll have seen this one more likely. You could even add Nuts as one of the demo bots for that page, as it was quite colorful and memorable, again if the teacher is expected to give people in the RW club a choice of what the club aims for, might be one to use there.
May also be worth noting there that rambots are not permitted on Robot Wars, if that is the goal of the school to at least attempt getting on there as a few have done, you need an active weapon to get on Robot Wars, ram bots do not have these, Tornado added some little piddly weapon purely to get on the newer series. You can do the same, but then not actually really use it and stick to ramming to get around it.
LiFePo4 might be worth adding to the alternative batteries, they have good density, longer lifetime (in a fighting robot, they'll probably get damaged well beyond a lifetime for one), they're also inherently magnitudes safer than the LiPos you focus on. I'm not entirely sure if focusing on LiPos is a good idea for school built robots to start with, mind.
Might also be worth noting the expected amount of £££ required to build each type of robot. Bare in mind that everything on the TV show that proudly annouces how cheap it was made, quickly ends up shredded. So with robots, cheaper is often not better if you want it to hold any weight in a battle.

That is a good guide though, and in the future you could easily adapt as a quick guide for all, rather than school club focussing.

If someone could double check the relay wiring diagram that would be great

the relay diagram appears to be fine
