HAZARD 2

Hi i am going to start a build diary on my robot hazard 2

It would be interesting to know the speed of it:
Its really fast It runs off 4x50:1 gear motors with 32mm wheels and a 180mah battery

I've got an equation
to calculate the velocity you do pi (3.1416) times the diameter of the wheels times the rpm
if you have a robot with 10inch wheels and 300rpm motors that is 8.9 MPH
but to calculate the rpm of the not you do velocity divided by pi times diameter
hope this helps

it uses some 180mah lossi bateries

some pics coming slightly later

Think I have a picture

most people upload to photobucket then copy the img codeinto their post (this embeds the image)

yeah I cant get onto photobucket
Can you still see the picture through the link?
Thanks for replying
I was kinda looking like a loner talking to myself :rofl:

lets try this

YES
If you see what I see then It has worked!
:proud: :mrgreen:

looks good!

Thanks very much!
Its all made of 0.5mm titanium
Dunno what grade

That's worked now :D

YAY
And guess what
Ive just made a youtube account
so maybe more videos
Not with my ict skills :rofl:

ok maybe not-confusing
Its really expensive aswell
50:1 gear motors £40 (someone could had told me they are £5 each) :lol:
bane bots speedos £75 (normally $60 but you had to pay import tax) :angry:
I have wasted £40 on lipos
£15 for a sheet of ti (finally a good deal)
wheels-about £10
planet 5-£50 maybe for sale with rm6 reciever probarbly £35 mint condition
battery charger £15
More or less £250

Another picture

Any more comments :mrgreen:

It looks really cool. Very compact electronics

thanks

and thats without the batteries
Thats why spectrum rxs are great in ants (there half the size of giant cod and planet 5!)

Its pretty much unimproveable!

I will bring it to barnsly (its seccond proper event)
Last time i came with a bot that was 2 gear motors strapped onto buisness card boxes :rofl: still it lasted

the spagetti monster strikes again :lol:
looks prety good, what does it weigh?

it is underweight at about 148grams
impossible!

YAY VIDEOS!
this is the robot (was)http://www.youtube.com/watch?v=ODo4U...3vkagtGau_kVwF
And this is its batteries (now :angry: )http://www.youtube.com/watch?v=eQzy6nCBP1s
any ideas whats happened?
COS IM REALLY ANGRY WITH LIPOS

It looked very fast! The links haven't worked though I had to copy and past it. Not sure why it didn't work though. The second link doesn't work even when I copy and paste it.

really?
hows this
http://www.youtube.com/watch?v=eQzy6nCBP1s

that will do for me! :mrgreen:

I cant link the other

it's definatly you, not the lipos.
dont let them run all the way down, it kills them

I dont know what to do
They just stay on 100% battery till their dead :angry:

How can I stop this happening?

can I get something to mechanicaly stop after like 10mins?

I can charge a 3.7v cell so Its not the chargers
Does anyone have any god forsaken lipos I can buy :(

Giant cod sell a small devise which beeps when the voltage gets too low (it will be too heavy to use in combat but you could have it plugged in during testing. It also shows you what voltage each cell is at and the voltage of the hole battery.
Edit: here is link - http://www.giantcod.co.uk/battery-teste ... 06198.html

That looks quite good
Anyone ever used this

I've bought one and it works fine- annoyingly I bought a the one which dent do 1 cell batteries.
