PRE-ASSEMBLED! (so you can just bung it on and start playing).
 
The mBot Gripper Picker-upper. Grab things and put them somewhere.

Comes with a free copy of the .sb2 program to run on mBlock.
 
Note: the mBot itself in the picture is not included. You are buying the gripper picker-upper assembly only. (should not need to say this but sometimes we get some really strange customers).
