Having trouble with your VEX IQ color sensor in your classroom? This mat is the solution. The VEX IQ color sensor senses the color green when it is exposed to fluorescent light. That can make it difficult to complete challenges that involve the robot sensing green (especially since one of the VEX cubes is Green). The solution is to have the color sensor pointing down towards a neutral color like yellow. Instead of using VEX cubes to complete challenges, like you find in the Carnegie Mellon Introduction to VEX IQ Programming, create colored cards out of construction paper. Using this mat in conjunction with those cards will make the color sensor behave more consistently and give your students confidence in the operation of the color sensor. My suggestion is to create at least four different colored construction paper swatches (red, green, blue, and black).
This is an FLL size mat at 44.75x92.75 inches
