Re: Yet another new guy!

my servo moves twice; once on powering up, to a random anticlockwise position, then again when the tx is turned on, to a set position. it's always the same position, which matches the tx settings. Always power the transmitter on first! If you don't the receiver only receives noise and any random si...

Re: Football / Hockey - rules?

Hello and welcome Ian! I'm not sure there have ever been any "official" rules for antweight football. :) It's usually a case of pick some teams (2 or more a side), chuck the ball in and stand well back! I think we've played for 3-5 minutes before. Depending on the battery capacity/technology you are...

Re: Tx and RX question

It is the receiver that gets bound to the transmitter. Although the transmitter has to send a bind message it doesn't know which receiver(s) are bound to it. Consequently several receivers can be bound to the same transmitter but each receiver can only be bound to a single transmitter. If you want t...

Re: First time building diary: Third Law

I think it's fair to say that cutting 1mm polycarbonate with scissors is easy enough, but that extra half a mm makes all the difference! Tin snips and wire cutters are a good suggestion for when the going gets too tough for scissors.

Re: Best battery for transmitter

That charger will be perfect for the NiMH batteries and will also be suitable for LiPo batteries when you want to get a bit more advanced. Note that the charger runs off 12V DC so you will need a suitable mains adaptor to go with it. There are some very similar chargers that have a mains power suppl...

Re: Best battery for transmitter

First of all, welcome! We're a friendly bunch (outside the arena at least) and this forum is a wealth of information. That transmitter and receiver looks fine for an antweight, plenty of channels and memories for when you get on to your second, third... robots :) You may want to check that "Mode 1" ...

Re: Dorset Robot Championship

Looks good, and I don't see any reason why day 2 couldn't be an AWS. Given a reasonable turnout the extra events (sumo etc) may have to be for the Friday only as it generally takes all day to get through the AWS fights. If you had a separate space (and people!) to run the obstacle course in parallel...

Re: New Arena

Size: We're planning on making the PC box around 1.2m x 1m, with a small trench between the arena and walls - does that sound about right? We don't want it too big and drag out battles, but I can't stand a small arena! A 1.2x1m box sounds about right, but what size fighting area does this give you?...

Re: Kosmos Build Diary

The robot only needs to fit in a 4 inch cube, it isn't limited to a 4 x 4 base. By fitting the robot diagonally in the cube it can be a lot longer than 4", but any acetate does need to fit in the cube. Bits poking out are not allowed! :)

Re: Using multiple small LiPos

It is the very thin size of those batteries that limits the discharge rate. They will (just) cope with 10C discharge so they might just work in an antweight as long as you change them between every fight.

Re: Using multiple small LiPos

Two motors at 120mA each (free-running, so about the lowest current you are likely to see) is more than 200mA. Are you sure about the 2C rating, as it's very low. Can you post a link to the battery specs? If the discharge rate (different to the charge rate) really is only 2C then the batteries will ...

Re: Using multiple small LiPos

Generally best not to connect cells in parallel. They will have (slightly) different voltages and the one at the higher voltage will discharge into the one at the lower voltage - with nothing to limit the current! No problem with connecting cells in series - that's what all battery packs do. 7.2V @ ...

Re: Sharing parts between two or more ants

No problem sharing transmitters between robots, almost everyone does it. As to parts, as others have said, you need to have 2 complete robots to tech check. Also, since your 2 robots will be in different groups it is possible that they could be in consecutive fights (last fight of group 1, first fig...
