Re: General questions for first robot
Having looked through the websites, I have made a draft shopping list of electric parts (minus the batteries and transmitter) to get. Could someone please double check that all these parts will work with one another?

Sabertooth 5A Motor Driver
298:1 Mini Metal Gear Motor
From robotbirds.com
18mm Baby Outrunner - C18-15-25
Robotbirds Pro 6 amp Brushless ESC V4
from micronradiocontrol.co.uk
DSM2 'Orange' 4 Channel Micro Receiver
As always, all help is greatly appreciated.

Re: General questions for first robot
mate, use a 50:1 motor for decent speed, that will be to slow
have a look at this:

Re: General questions for first robot
I found a 56:1 motor on the website I am using, would that work? My only concern is that the description says
'If you're looking for a speedy motor with a reasonable amount of torque (for say, moving a small robot that isn't going to fight in a Sumo contest)..'
Which sounds to me like the robot will have little pushing power.

ignore active robots, just ignore it.
most ants run 50:1s they can push fine

Re: General questions for first robot
They may not be good for mini sumo robots where you have 500g to play with but for an ant they should have enough torque.

Re: General questions for first robot
I used to run 75.7:1 motors on Jigsaw with 32mm wheels and found it was too slow to keep up - it runs 50:1 HP motors now (which are fast becoming the standard: http://www.robotbits.co.uk/motors-gearb ... od_10.html ) with the same wheels and has more speed and power than it'll ever need!
As much torque as 298:1 motors would give you, you'll move far, far, far too slow to ever be able to make use of it.
The other components look mostly fine, the spinner motor seems a bit on the small side though - go for an outrunner weighing about 25-30g for a decent spinner.

Re: General questions for first robot
The brushless spinner and controller look OK, I think they're the same ones that Antipathy uses. An 18mm brushless is plenty for an antweight spinner.
You will never be able to use all the torque that typical antweight motors can produce. I've never known anyone stall a drive motor yet - there simply isn't enough mass involved...

Re: General questions for first robot
The reason I am worried about the drive motors is that most spinners I have seen loose battles because they go flying when they make contact with another robot. I want to try and make sure that this will not happen to me.

Re: General questions for first robot
While that does often happen in many cases the robot is airbourn so the drive and wheels have no effect.
Even if the are still on the surface it is far more about grip than torque so all you can do is get the grippiest tyres and as much weight over the wheels as possible and hope.

I have somehow managed to burn out 2 on Bulletproof in the last 5 months. What cause, I have no idea because I wasn't using it either timeI've never known anyone stall a drive motor yet - there simply isn't enough mass involved...
