All of the WowWee walkers perform much better on even surfaces than uneven ones.
They don't pick up their feet very far, and their balance points do not adapt to changing conditions, so they are often challenged by any inclines or minor bumps or ridges.

Thick carpet will trip up an RSV2 everytime. The RoboReptile has more stability than the two legged bots.

I have read reports of people having the foot tips and pads worn down from running the robots on abrasive surfaces like concrete. There are a few tips on the community concerning how to deal with worn foot pads.

As for the question concerning indoors versus outdoors, the robots rely on InfraRed remote control and ranging. The infrared signals can be affected by unfiltered sunlight.

Lol. Mr. Scott. That's awesome.

I'm pretty sure the sound sensors are turned off while the robots are moving. The cacophony of motors and gears would trigger noise "hits" if they ears were monitored while it clunked along.

Check your manual for what remote control combination turns the sound sensors on again when the robot is sitting still.
