Which 2.2 crawler has the smallest turning radius of them all (stock or with upgrades)? I need it for my robotics project...
I'm now choosing between the ax10 kit with rear steering or stock creeper ('cuz it has diffs that can be unlocked). Which one would you pick?
Please reply! Thanks for help!

I've run TLT's, Axial's, Wheely King's, Clods, TXT's and now a Creeper. The Creeper, stock out of the box even with both diffs locked, out turns anything I've seen with the same wheelbase.

Creeper.

kasper · 05-13-2009, 11:26 AM

I really like my creeper

roksraka · 05-13-2009, 11:43 AM

thanks for help guys! i think there is no doubt about what i'm going to buy now... still keep the info coming!

(btw... how does it crawl? is it better than the ax10?)

What do you need it to do for your project? With stock front and rear dig, the losi will out turn any crawler out there imo. Just my two copper discs though.

AX10 with four wheel steer will definitely out turn a creeper (without rear steer)

remember that steering radius is also a funtion of wheelbase so the shorter you can get it the better.

If you were going to wire the creeper to unlock the diffs why not just get a dig unit for the AX-10 instead? 0 turning radius

i'd like my robot to follow some GPS waypoint and avoid the obstacles outdoor...you know... However, I can use the dig while rc crawling, for robotics, no way! it would be way to complicated (for me) to control it. Thanks for help guys!

So, your steering control will always turn to lock (100%) until it gets input it is back on a way point via GPS, then return to zero steering?

What are your perimeter detection methods - senors, vision, other?

One way to control DIG decision would be a dual input sensor on the front. Long range, short range.
Long range detection = turn.
Short range detection = turn + DIG.

But what type of objects woudl come up in short range detection that had not been already detected by long range?

roksraka · 05-13-2009, 02:29 PM

i will have a GPS receiver and a compass sensor, so the robot will know in which direction it's pointing. But as you said, steering goes to maximum, drives forward until it's pointing in the direction of the waypoint, steering back to zero and here we go! (in theory) it will also be equipped with 3 ultrasonic range finders to avoid the obstacles along the way!

I'm might incorporate the dig into the design later, when my theory and design will be fully tested and developed...

oh! i also saw, that the front and rear axles are the same. so when i get my creeper (not before the end of the semester), i will be able to convert it to 4 wheel steering!!! 2 axles turning at 40 degrees with unlocked differentials! this will be the most maneuverable crawler EVER!

If I am not mistaken, you can get the Axial with unlocked differentials...

The RTR comes with a FRONT unlocked diff. But the steering sucks on an Axial compared to the Creeper. Don't get me wrong if I was just going to buy a crawler it would be an Axial but if you want the best steering it would be the Creeper.

i have ran both tlt and ax-10. imo the ax-10 sucked a$$. i would love to try out creepers. tlt's are great but cost alot of money to get them comp ready
