PostSubject: Antweight Drive Motors   Sun May 23, 2010 9:16 pm

I'm looking around at drive motors for ants at the moment, and I'm curious if anyone's had experience using these:

Do they seem good enough for a two-wheel drive, or would I need something a bit beefier?

EDIT: While I'm at it, these are the ESCs I've picked out for now:

Those gearmotors will get the job done, but they don't last. For a 2wd bot, you may want to buy 4 of them, and make them fairly easy to replace in your design. I definitely recommend using the brackets RMP sells with them (http://www.robotmarketplace.com/products/0-PL989.html) because they're contoured to clip in with the gearbox quite nicely. The difference between the white (extended) and black is that the white ones have the mounting holes for the bracket somewhere near the middle of the gearmotor assembly, while the black ones have the holes up front by the gearhead.

As far as the scorpion goes, I haven't actually used that particular one, but I've heard good things about Scorpion's reputation. Personally, if I were to design a bot NOT using Fingertech's tinyESCs (which are really tiny, but not quite as durable as some of the other ones out there), I like Sabertooths, although Richard hasn't had much luck with them... I usually use a pair of TinyESCs.

Maxons are really the way to go with antweight drive, but man, they're EXPENSIVE. And kinda hard to get a hold of too...

Side Note: I found some interesting ESCs that may work well for insect bot drives (and possibly hobbyweights) while poking around:

http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=9090&Product_Name=Turnigy_20A_BRUSHED_ESC

http://hobbyking.com/hobbyking/store/uh_viewItem.asp?idProduct=6468&Product_Name=Turnigy_30A_BRUSHED_ESC

(I'm not going to use these on my antweight though, they're a little on the large side)

Another cool Brushed ESC:
http://www.sparkfun.com/commerce/product_info.php?products_id=9668
50A continuous, PWM controlled, accepts 9-24V (fan only works with 12V though).

The hobbycity escs posted above are not reversible.

On a related note, be careful when using hobby escs for robot use. Several reasons:
1) hobby controllers have a delay going in reverse because some racing scenarios call for a reverse delay. Some delays are programmable but nearly impossible to get to 0.0 seconds. Tekin Rebels were popular because they could get very close, but never goes away. Duratrax are a no no.
2) hobby controllers have a significantly decreased reverse amperage. Most notable are boat escs which feature reverse. These typically do not suffer from the reverse delay but they are more prone to exploding because of the decreased current. ex. Mtroniks

Heed the warnings!

yes, the spark motors are pretty good. They're a "replacement" for the banebots 18mm gearmotors which were of... questionable quality.

buy them from rmp so you don't have to ship from canada!
