Do you know Lego MindStorms ? The last one is the Ev3 serie (http://www.lego.com/fr-fr/mindstorms/). One particularity of this version compared to the previous ones is the possibility to plug a Wifi key and connect via TCP.
So, if you have this material (one Mindstorms Ev3, one compatible Wifi key), you can control your robot with Pharo !
Just load these lines:
Gofer it url: 'http://smalltalkhub.com/mc/JLaval/JetStorm/main' username: '' password: ''; package: 'ConfigurationOfJetStorm'; load. (Smalltalk at: #ConfigurationOfJetStorm) loadBleedingEdge.
I know also that for Christmas, it is not possible to learn a new API, we all have a lot of other things to do ! So, you can play with it into Phratch.
For that, just load Phratch and the package EV3Phratch as follow.

Have fun !
