RC robot for 4 year old?

[shambaby]

Posted a thread earlier asking for suggestions for my boy's main present, and he has since announced he would like a 'robot with controls' after playing with one at a friend's house. Does anyone have any recommendations for one which is nice and sturdy, with simple controls? Thanks in advance x
