Well,claimed that it can walk,make me a little bit disappointed.It can't do the actual walk but rather than like paddling with it rear legs.
The sample program is to make it move forward when it's detecting an object in front of it and try to bite to protect its territory when too close with object.After it has attacked,it'll return to its post back.(Read more,ok)
You can watch this video to see it.
Shh..its secret ok it really moves with its two legs.
Well,can't blame LEGO for this,because this is just the sample they provided and I'm understood they want to make it simpler as much as possible so kid can built it also too.
At least I've fun with him I give my pet some biscuit for dinner.I hope he'll like it.
Stuck at the middle???Maybe I can help you.Feel free to ask,ok :D
