One of the area that is quickly emerging as a feasible sensor for students to use to meet the challenges set by many robotic competitions is for Vision Sensing.
I would love MakeBlock to have access to the PixyCam sot ath students can include it in their projects.
See Mindsensors solutions for the Lego EV3 Pixy Adaptor and Cam
There is also a Pan-Tilt version available that would be invaluable on the MakeBlock robots
