I've read all that I could on arduino for robotics gain a world of experience and have been using an arduino uno board to hammer down the concepts.
Now I want to buy my first robot kit and have some clear goals so here they are:
Dagu Quadot which uses a Arduino Mega replica( Black Spider) with an Atmega 1280 at it's heart http://robosavvy.com/store/product_info.php/products_id/1669
The DfRobot 4WD which has been very popular and uses a Romeo 328. http://robosavvy.com/store/product_info.php/cPath/21_1200/products_id/989
I plan on on adding a ultrasensor to either of them and make it an obstacle avoiding robot. The most important part is I plan on using Oleg's Host USB 2.0 shield that allows ADB connection to Android which basically transforms it into a Google ADK and removes the hassle of bluetooth connectivity when you need reliability and speed but I'm not sure if any of these boards have problems with the USB shield, this is untested territory.
The dfRobot has 4 motors while the Dagu has 8 servos.
Any opinions? I just wanna get some feeling of accomplishment because it was always my dream to build a robot, I know this is a kit but I can still add a lot of awesome things to it to make it into my own creation.
