Lego Mindstorms (the current set EV3) has a graphical language (cf http://www.education.rec.ri.cmu.edu/content/lego/ev3/preview/ http://www.education.rec.ri.cmu.edu/content/lego/ev3/preview... ) with turtle-ish capability. There are also alternative firmwares (e.g. http://www.ev3dev.org/ http://www.ev3dev.org/ ) which let you use more or less the language you want, but you loose the IDE integration and the easy setup. And the original firmware is open-source too: https://github.com/mindboards/ev3sources https://github.com/mindboards/ev3sources
