Our A4WD mobile robot platform just got a review from rugcommunity. Here is the conclusion
"Overall this is a great kit to get started with. This kit can be used by beginners to advanced users. We truly thought the quality of the construction of the kit was superb. Especially for the price. You just can't beat it! We have yet to find any other robotic platform on the market that is as good and broad as this one for the money."
