It's awesome! Don't forget to install the updated firmware after you assemble it. If you're using a computer with windows OS, use one with version 7 upwards because you'll have to install a software called mblock 5 to install the firmware...the older version of mblock is obsolete. Make sure that your bot makes 3 loud beeps when you turn it on and turns of white LEDs the first time...if it's one soft, short beep then something isn't correct so install firmware. Have fun.
