Love these little bots! Hope you dont mind me asking a question........ I have the Nano2, how do you get a spinner to work with it? I only have 2 motors connected and have one servo output.

Cheers!

scottylad7: You connect the servo output to the input of a brushless ESC, also the power, and it will drive the three wires required for a brushless motor. Some of the ESCs are programmable and can have some parameters changed in the firmware through a suitable interface cable.

Do note you can't plug a brushless ESC's servo lead directly into a nanotwo V3, the V3 outputs full battery voltage on the servo positive line. For most brushless ESC's you need to cut the red servo wire to prevent this full battery voltage from damaging the ESC.

Others have already answered, but I might as well try and give a full explanation.

For a spinner you will need a brushless motor, and a brushless esc to drive it. The esc will have 3 sets of wires;
A) 3 wires to connect to the motor.
B) 2 wires for power (to be connected to the power wires between the battery plug and the NanoTwo)
C) a servo plug for the signal, this connects to the NanoTwo servo plug (with the centre red wire disconnected)

If you're looking for parts the Afro 12A esc and the Quanum Be1806 motor are good choices.

I'm just going to leave this here...

No need to bolt on some extra armour though, I'm almost certainly not building an antweight with four spinners :wink:

I assume this is the walker you have been teasing? Look forward to seeing it. Does it use spinner forces to walk?

Yeah, something like that. I'm still far from sure it's going to work, I've not done any calculations beyond rough estimates in my head, but I'll guess we'll see soon enough.

It's starting to take shape...

Rather more bodged than normal, but it's more of a prototype/proof of concept than a finished design right now.

looks good... saw a simmilar idea with the dual spinners and using the gyro to steer... glad to see more of this idea as i think its a pretty cool bot to have in your team...

so far it definitely has the same look/style of your other bots so it fits the team well... cant wait to see more progress

Cheers Kyro, It does currently look very similar to a couple of vibration driven bristlebots that I've seen, but the mechanism is very different (and I think unique). If it works as expected this one should move by waddling in a rather penguin like fashion.
