Re: Build Diary for a new antweight
10/10 on style points! Let's hope it fights just as well. It does look like it'll be a worthy opponent in the ant arena! Great job

Re: Build Diary for a new antweight
Thank you everyone. I've had quite a lazy week so I've started on rebuilding my first robot. Made a quick mock up out of paper, before cutting it out in polycarb.
And I've also bent the chassis with the help of the vice, very handy.
I've also drilled some 4mm holes for the wheels and some 2mm here and there to screw the back and side panels together. The original had its wheels on the inside but seeing as this one will have less space on the inside, I've decided to instead add them to the outside and maybe put some more decorative wheelguards in.

Re: Build Diary for a new antweight
So, as I didn't have much going on today until robot wars, I spent most of the day working on rebuilding Oni. I drilled holes into the top panels, and added a couple of hinges, as well as bending the sides of the flipper for strength and to slide it into the hinges.
Unfortunately I forgot to take any more pictures until I was finished, but I bent a paper clip to fit into the hinges and the flipper, fitted all the electronics, the motors held with zip ties and the servo with two zip ties chained as suggested. I also bent another paper clip and fitted if through the servo arm and the flipper to work as a four bar lifter. Finally, I screwed all the top panels on, and a small polycarb plate to lessen the ground clearance of the flipper so it can get under things.
Eventually this should be replaced with an aluminium scoop plate, and a self righting fin will be added as well as some artwork. I still have 25g to play with and the robot fits into the size limits so overall I think it's been pretty successful.

Re: Build Diary for a new antweight
So after messing with the hinges on the flipper and having to essentially replace all of them, I've made it so the flipper opens more and sort of springs open giving a better flip. I've also added a fin to the top for self righting but I am unable to find a way for the robot to right itself from on its side, no matter how many fins I add.
Looks a little like Make-A-Bot.
I've also added some artwork to the back and underside of the robot. The flames look a little generic, but they remind me of my favourite robot from the original robot wars series, Wild Thing so it's ok by me haha. I plan to make the front face plates look a little less generic.

Re: Build Diary for a new antweight
I love it 8) real classy looking retro flipper.

Re: Build Diary for a new antweight
Righting from the side is quite difficult to do reliably.
You have to spend a long time getting the shape and weight distribution correct and then you end up with something the shape of RONNY...
Alternatively you can try adding a boss sticking out from close to the rim of each wheel. These then act as a cam to lever the robot over if it is stuck on its side.
Both these solutions increase the overall width of the robot somewhat which may cause a problem fitting in the cube.

Re: Build Diary for a new antweight
I got it down on the previous version, with a couple pieces of polycarb (superglued on, big mistake) it would flip itself back over every time. Unfortunately that doesn't seem to work with the new improved version. I'll have a mess around with it tomorrow.

Your team is coming together rather quickly! Another fantastic looking bot.

Re: Build Diary for a new antweight
Thanks, I turned the fin upside down on the robot so it can right itself from any angle, as a bit of clever driving rolls in
T onto its back where it springs back into its wheels. Also aluminium came today so I played around with a front scoop. At the minute I have a narrow square of aluminium on the flipper, but I also plan for interchangeable front scoops.

Re: Build Diary for a new antweight
So Oni II is all finished now. The flipper's a little unreliable, but I've figured out how to make it work as well as it should. There are currently two front flipper blades, a narrow one, and the large front scoop on the robot in the image. I also plan to make a second scoop from titanium, but I think that will be a little more difficult.
Glad it's finished, I'll see what I can do next.
