These are some of the creations made by my 7th and 8th grade students this semester in Lego Robotics. The R2d2 units are remoted controlled with sound and lights. Johnny 5 is remote controlled. Yoda's head is motorized and he speaks 6 different movie phrases when the motion sensor is activated. The music box plays music, opens it top and spins 2 minifigures with the push of a touch sensor, then shuts with the touch of a 2nd touch sensor. Lots of sumo bots ready to battle and more.
