Left connector is the balance lead one and goes into the charger, right connectors are the micro jst's for your batteries.

Re: charging smaller lipo batteries

That one can only do 2s or 3s lipo's. You could probably cheat and solder a couple of micro jst connectors to the balance lead and get it to treat the cells a 2s or 3s battery. As it's balancing the cells and you won't be soldering cells together you shouldn't get any explosions.

Re: Mechanisms

Would allowing slip in the drive via a friction clutch or belt work? Static friction coefficient (not slipping) is generally more than Dynamic friction coefficient (slipping) so when the output shaft is stalled the load on it is reduced making more power available to the other outputs. I may be talk...

Re: Flea weight quastions

Yes it does. It has to fit in a 3" by 3" cube but that is in any orientation so you can have a robot longer/wider than 3".

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: Ant weight arena

I'd build it like an antweight flipper but with a much bigger servo. A servo tester with a push button attached in the right place would allow you to fire it without using a transmitter.

Re: Toyota Challenge Program

I'm pretty certain that if you send a pulsout command every 20ms to a servo you can drive it. You'll have to figure out what value to give the pulsout as it depends on the clock speed of the chip. Then chuck it in with something like this so you don't have to do as much maths on the chip, save an ou...

Re: New Roboteer!

Tried it for a 4s lipo, blew up 3/4 of the cells in the process. If you do want to solder them together then it's easy to pull of the plastic cap but be careful about shorting out the connections (Fried one cell that way). I cut off the micro jst connectors and soldered the remaining wire to the cor...

Is that the one you meant?
I can really see the resemblance.
