Technically if you read the rules (section 7.8-lipos) there's no mention of the baseplate rule. It's currently an advisory, but I'd suggest a metal base plate will make it's way into the rules eventually.
An ignited lipo wouldn't have any trouble melting hdpe
Yup thought so, just checking so that if i do eventually go to Lipo i wont make any daft mistakes
The way Bitza is designed means all the expensive components are in a metal casing, and then mounted right in the middle of the robot a good distance from the floor, so shouldn't be a problem.
The drive motors are 12v Argos Drills, run by 15a Electonize's so can't draw too much current there.
As I don't know any specs about the 24v Drill motor we're using for the disk, I'm going to have to experiment! As I start I'm thinking a 10:1 reduction?
Given the bouts are each 3mins and as per your advise I'll be balancing them after each round I'm thinking 2,650mah upwards will suffice, hopefully......
Can't spend a huge amount, so I'll post what ever Li-Po I pick in the end, probs be a cheapy though!
As for wire what do you use David? I'm currently using stiff 10awg? And where do you get it?
i for one an cirtainly interested in how effective a drill motor will be for a disk.
if it is a half good weapon, it might be my next weapon. a spinner powered by a drill motor
Why is that so crazy?
Drill motors work fine. Used them in the featherweight typhoon bot and used two in the light weights. They won't give you the instant spin up from more powerful motors but will do the job.
Ratio out the gearbox you might wanna actually gear it up, the output from a standard drill gearbox is around the 800rpm mark, little bit slow in my book!
Good point Dave, I don't run my batteries until they're dead but there have been times that I haven't been able to charge them between battles so it's nice to know that I can run them again and still get a full fight from them.
My plan was to take take the gear box off the motor and then do a 10:1 reduction.
cool, only issue i could see you having with that is attaching something to the output shaft of the motor as they are tiny (only a few mm). You might as well look at getting a speed 900, decent power and a 6mm shaft. Not too expensive either.
For wire/connections I use silicon/wet noodle wire purchased from robotmarketplace.com I think robochallenge are also starting to stock wet noodle wire now though... Drop grant a pm.
Connectors I use deans connectors, there rated upto 70a contin, you can pick them up cheaply of eBay/robochallenge
As Gary said a speed 900 would be a good alternative... But if uve got a bit more weight spare you could go for a car fan motor. On 24v there really good. And better yet cheap of eBay/scrap yard
Would you say the car fan motor would be better than the 24v Drill motor? Car fan motor is pretty much in the Bitza spirit!
