So since I last posted I have been busy doing what parts I can of Robot build number 1. I'm still waiting to hear about the nano kit, and have begun thinking about alternatives just in case, but in the meantime I got to work on the bits I could, namely the polycarbonate bits.
I now have a body for the robot to live in!
Now, I just wanted to say real quick. I read on here several times before I started "oh, that 1.5mm poly, easy peasy, cut it with scissors, bend it by hand no problem at all". Well. Phooey. Easy isn't a word I'd have chosen haha. Several nipped fingers, a bunch of swear words, and three sheets of trial and error later, ehh, I guess by the end I'd kinda got the hang of it. My last few goes at bending were much better than the first lol. I broke a pair of scissors too! Easy to cut and and bend, my bum. I did it though!
Worth me mentioning again - umm, this is not a super high tech project. I bought a cheap knock off dremel drill, a pack of sandpaper, and a clamp. I don't have a workshop or much experience at all with this stuff. Go easy on the new guy haha. My last experience of workshop/electronics was terribly run GCSE classes, which was... a few years back now. I'm learning and relearning a bunch though.
Anyways on to the robot!
It's gonna be 4wd invertable push bot, keeping simple this first time. There'll likely be other more complicated projects (my housemate is also a huge fan and probably when this one is done me and him will make a 2nd) but first time round I've got enough on to be learning as it is.
Working name for the little guy - Third Law. Thought it appropriate for a pusher robot who's game plan will basically always be - drive at the other robot head on again and again and again. Please do let me know if you guys know of another robot who pinched that name already hehe.
My whole plan was to go for strength/resilience on the front and rear facing. I've seen lots of videos of the spinning weapons people are squeezing into 150g, and damn... So my intention is make something that can survive driving head on into one of those
get some of that equal/opposite jazz working and try to out tank the weapon. My thinking is that with 4wd I ought to be able to shove back pretty well. Also the sides (and more importantly the wheels) will be well covered, though side on the build is nothing like as strong as front to back. Really i feel this thing is for head on collision.
The weight of the thing bolted together - approx 65-68 grams. I last weighed it before I'd finished the lid part so I have to rough it to about 68g. Should hopefully fit into 150g with a nano kit, battery, etc. I've done an estimate and will be very close
Maybe I end up needing to drill a few holes.
Dimensions - it should *just* fit into the cube on diagonal. 122mm long, 96mm wide
Hopefully soon this diary can turn to internal stuff. I think, for now, I've done what I can.
Some pictures!
What kind of drill did you use for the holes and screws?
