Bandit's Bot-Building Bonanza
With the completion of my first bot comes the obligatory build diary for Team Bandit! Thanks to everyone here my first bot, a currently unnamed flipper, is up and running! Special thanks to Rory for the amazing Nanotwo and to Alex for answering my questions.
Front
and back!
The bot consists of an ABS 3D printed frame with inserted polycarbonate panels. I used the Rory approved set up of the Nanotwo kit and his recommended servo and battery. The bot is around 9cm wide, 11.5cm long and 3.5cm in height. It comfortably fits in the four inch cute due to the angle sback panel. The bot weighs in at 113g! so quite a bit under weight. Perhaps a metal panel could be added to the flipper or extra support inside. Any suggestions for what to do with the extra weight welcome! Oh, and it can self right (because I know you guys ere wondering!
The whole project including a transmitter and batteries/charger etc cost around £100
I'm pretty happy with how it turned out! Already thinking about the next one. now I just need somebody to fight...

Re: Bandit's Bot-Building Blog
ooooh, I love that, the frame/polycarb construction looks really really nice it'll be good to see what you have planned after that if this is your first attempt! I would add a metal (Ti?) scoop on the front and maybe bend it around the sides, but it looks pretty good to me. Maybe a bigger battery for testing/not having to charge during events purposes?

Re: Bandit's Bot-Building Blog
Thank you The photo's don't quite do it justice, the orange is a bit stronger irl too. I think a Ti skirt would add some protection but also look pretty cool. Not sure if there's enough room for a larger battery though unfortunately.

Re: Bandit's Bot-Building Blog
That came out very nicely
It looks great and should be one to watch out for in the arena, plus all done on a fairly tight budget.

Re: Bandit's Bot-Building Blog
Thanks Alex! I appreciate it. Hopefully I'll be able to get down to an event sometime in the near future. In regards to the budget I found a website called 3Dhubs.com where you put in what type of material and the colour you want and it hooks you up with 3D printers near you that can do it. (actually the guy that did mine said he'd recently done a couple of other antweights so I figure some of you already use it) The pricing is very reasonable and students get 25% discount by signing in with their university email address! would recommend to anyone who doesn't own a printer

Re: Bandit's Bot-Building Blog
A look at the internals
here's a better photo of inside the bot. The servo rests on a table which the Nanotwo and wires fit underneath, the motor mounts screw to a raised section of the base giving it a very low ground clearance and the flipper mechanism is bodged from a couple of nuts and a paperclip!!! The flipper itself in hinged on 3D printed nubs that fit into slots on the bot with a strip of polycarb to hold them in. The battery fits in the front (not in there in this photo) with a bit of blue-tac to hold it in place.. haha. The one thing this bot doesn't have is a switch although the battery can be very easily disconnected when the flipper is lifted.

Re: Bandit's Bot-Building Blog
Looking very good. The 3D printed chassis framework with the polycarb panels really give it a distinctive look. Flipper works nicely too by the looks of things. Looks pretty sturdy too, and shape reminds me of some of the heavyweights. Any ideas for a name?

Re: Bandit's Bot-Building Blog
Thanks! seems pretty sturdy although obviously not battle tested yet. I drove it off my dining room table into a hard floor by accident and it was fine though! I was kinda going for a miniature heavyweight look so I'm glad that came across, It wasn't inspired by any single one in particular though. No name ideas yet really! The only one I thought of was Satsuma due to the colour but I wanted something a little more punny. Satsumo maybe?

Re: Bandit's Bot-Building Blog
It is nice to see some one trying not only to make a robot that looks different but also one that is an original method of construction.
Most impressive especially for a first robot I look forward to seeing it in action.

Re: Bandit's Bot-Building Blog
Thanks again. This means a lot coming from all you experienced roboteers. I'm glad you like the design! I just hope it can perform well!
