4WD on a NanoTwo

Post by PorkJoshage » Fri Feb 02, 2018 3:25 pm

Hello all, complete newbie here.

I'm making an antweight for a family member's birthday, and he's asked that it be a 4WD pusher, so how would I go about wiring a NanoTwo to have it run 4WD?

Sorry if this is an easy solve, but I've literally no knowledge of wiring whatsoever and got directed here by a friend. :(
If you want a true indicator of skill level, I've just about finished acquainting myself with how to solder things. XD

Thanks in advance everybody.

Yayyy a technical one that I can answer 8)

I've just done this myself. You wire the nano to one pair of motors, then wire the 2nd pair in parallel. Just wire the +ve and - ve motor terminals on each side of drive to the equivalent on 2nd motor for that side.

If one side runs the wrong way, swap terminals on the ESC wires to that side.

Like this, though maybe your connections will be less gorey than mine

Thank Derek, I'll give it a go!

Would you do the same thing if you wanted to make a 4WD pusher with a DasMikro?

Yes.

I had my 4wd flipper working on a Dasmikro fine - until a couple of weeks ago when the Dasmikro ESC decided to fail spectacularly with smoke.

But my own measurements suggest that the stall current for these little motors is < 1A, so I think 2 in parallel (per channel) should be ok. Especially if they're geared so they never stall (mine never stall, the wheels spin first, but it might depend on the gearing ratio and the construction of the robot)
Robot: Betsie - RaspberryPi controlled flipper bot with gyro stablisation - too clever for her own good?

Yeah, I’ve heard that DasMikro’s can be temperamental at times. But I figured I can get away with using one if I don’t attach a weapon servo and just make a pusher...hopefully.
