Welcome back to Lego EV 3 class 4. We are half way through the course. We put many skills in our hand, including color sensor, touch sensor and key pads. We can build a robot that reacts to the touch. Touch to stop, touch keypad to restart, reverse, make turn etc. We are reinforce the safety driving practice by add more sound and light effects while we reverse driving or make turns. The faster student also tried touch-less stop. Next week, we are going to put all these skill into a line following robot, that can stop at red light, go at green light, and following a curved black line. Thank you all for setting up and clean up the classroom.
Lego EV3 Reverse Driving
Welcome back to our challenge class 4. Today we reviewed what we have learned from the first three classes. On the hardware side, we have tried large motor, color sensor, key pad and motor encoder. On the software side, we have learned loop and switch, variables, math modules. I have build robot that can read colors, go forward, backward, and self parking to the right. Today, we add a new capability to the robot, react to the touch. Once the robot touch the wall, it can stop, fire laser, back off, etc… Kids get creative about what they can do with the ev3. Next class, we will use color sensor again. We are going to build a traffic light detector. Red means stop, and Green means? Thank you everyone. See you next week.
