This a well designed, Arduino compatible mobile robot development platform,you can build it and program it easily with tons of published free codes. The high-strength aluminum alloy body material provides flexibility in rapid movement particularly in outdoor grass, gravel, sand or sloped surface. Moreover, you can add variety of sensors to make it more interesting.
Good Chasis, but the wheels have bad quality, all come crooked!!! And now I have noted that I have to replace the one of the reduction+motor because it is brooken and I don't know if Seed Depot will sell some spare parts. Could anyone tell me where can I buy some spare parts of the reduction/motor???

Epic, just epic chassis. I have my robot built with a sonar on the front (the Seeedstudio one). This robot is easy to set up. You will however need a motor driver if you are using an Arduino - you don't want to connect the motors to GPIO pins as you will break your Arduino. The motor driver shield works nicely for this, so don't forget to pick it up.
This robot has enough room for sensors and I have mine working with a Duemilanove and two shields: 1 with RF receiver and compass, and 1 is the motor driver shield.
There is a battery holder in the bottom compartment, but I do not use that. There is room for 4xAA, giving at most 6 VDC (nonrechargable). I'd recommend getting a racing pack or putting two to three LiPo batteries parallel so you get 7,4VDC or 11,1VDC. I have a 9.6VDC 4200mAh pack and that works great. You'll get some serious speed then and your robot will run for ages.
