Motors for Nanoweights

Hello,

Would 3V motors rated for a max load of 0.2mNm and max power 152mW be suitable for use in a nanoweight?

Additionally, could someone point me in the direction of some suitable alternatives?

Any info is appreciated, thanks in advance.

Re: Using multiple small LiPos

The batteries I'm looking at are found here:

I'm looking at the 100mAh batteries, though since it doesn't look like these will be decent alternative for an ant, I'll probably need to redesign the body.

Re: Using multiple small LiPos

Discharge rate appears to be 2C, so it will peak at 200mA. I'm planning to use Pololu HP motors. Motor stats are as follows: Free-run speed @ 6V: 1000 rpm Free-run current @ 6V: 120 mA Stall current @ 6V: 1600 mA Stall torque @ 6V: 9 oz·in Motor type: 1.6A stall @ 6V (HP 6V) Would a battery of 7.4V,...

Using multiple small LiPos

Hello, Since the design of one of my robots is too small for the batteries I currently use, I've needed to look for smaller alternatives. I've managed to find some 3.7V 100mAh LiPos that should work, however to get the power I need, I will need to use at least 2 LiPos. I've come up with the followin...

Counterweights on Axes

Hello,
Does anyone know whether adding a counterweight onto an axe is a good idea and what effect it will have on a robot when the axe is used?
Also, would it be better to have a longer axe with no counterweight, or a shorter axe with a counter weight
Thanks in advance for useful info.

Re: TinyTwo Speed Controllers

Considering selling these as starter kits: http://i.imgur.com/aSl1DrJ.jpg?1 It's a LemonRX connected and heat shrunk to an N2LV in a really convenient little package; only has 3 sets of wires to worry about and is really small. Nearly all my robots are based of these; It's just really easy as I can...

Re: Return of Battlebots

I heard about the scripted reality part, that's only going to be the between fights fortunately. As for the 250lb weight limit, the only other place I saw that was on Twitter (not a page related to the show's production), but apparently they'll be making it so that robots of different weight categor...

Re: British Bulldog ?

I would say that with the current arena size, 6 robots would be an ideal number, and to make it so that the game doesn't end too quickly, the bulldog has to push the other robots out of the arena rather than just touch them.

3d printed size limit cubes

Hi, would anyone be able to provide a link to a 4 inch cube that could be bought off of a 3d printing site such as shapeways.
Links to 3 inch and 2 inch cubes would also be appreciated.

Thanks.

Controller/reciever competability

Hi, I was wondering if any 2.4GHz controller could be used with a robot with any 2.4GHz receiver or would only certain receivers be capable of being used with controllers made by the same group that are designed to be compatible. As an example, I have a Spektrum controller, so would I only be able t...
