I plan to use my robot with Arlo hardware outside sometime. The main reason I haven't is because I didn't want to get the wheels dirty.
I'm not using the Arlo base but the distance between the wheels on my robot is the same as the Arlo. I don't think the Arlo's wheels or casters would have any trouble with concrete or asphalt.
One concern I had with the Arlo design was how little ground clearance there was when the battery tray was added to the bottom of the robot.
I was hoping to leave the bottom side of my robot open in order to increase the ground clearance.
When I first built my robot, I used used a couple of bolts to hold the platform to the motor/wheel mounts.
As I added addition hardware, the robot kind sagged in the middle.
I added some aluminum "L" beams in an attempt to reduce the sag.
I'm not thrilled with the results. I used material I had on hand but I think some lower profile hardware would be a good idea. The nylon bolts I had available kind of stick out too much. I also think the dimensions of the support pieces could be improved.
I think something similar to what I did (but done well) could improve the ground clearance of the Arlo. Though really, if you're going to use the Arlo on flat ground, the battery tray shouldn't be a problem.
I should point out, I'm using 6mm foam PVC (aka expanded PVC). I think the HDPE used in the Arlo is more rigid than the material I'm using. I had the foamed PVC on hand (It's generally great stuff for robots). I learned about foamed PVC here on the forum from Gordon McComb.
