Robotics day two

Today I experimented and learned about 3 different sensors, the touch sensor, ultrasonic sensor and the color sensor. The touch sensor is like a button so you can program it to do things when it is touched. The ultrasonic sensor is like the touch sensor but from a long range. Colors sensors allow you to activate thing when a certain color is detected. We also began to arm up our robot for battle. A small drill and stegosaurus-like tail and some spikes. I also started on making a custom movement system for the robot.
