Lego EV3 Parallel parking

Welcome to class 3, self driving parallel parking challenge. Today’s challenge is to build two programs: open loop parallel parking, and close loop one button starter. The parking program will drive the robot forward, then park to the right hand side. The starter program will use two button to control the sound system, press 3 to start, press 5 to stop. You will find lot of these kind of operation everyday, like in elevator, or your TV remote controller. Now we have more tools in your tool box. Next week, we are going to use touch sensor to make robot react to the environment. Thank all students and volunteers.

Lego EV3 Parallel parking

Welcome to the class 3, lego self driving car. We reviewed the self driving history, only 14 years. See “The Great Robot Race ” for the full story. (https://www.youtube.com/watch?v=Qh4wc03rea4). Today, we programmed the robot to do parallel parking based on open loop programming. We also complete a one button start program to start and stop the robot on command. Now we have some important tools in our tool box(color sensor, large motors, key pad, p controller, parking, self lock starter). Next week we are going to program the robot can do bump and reverse operation. Thanks again for the cleaning.

Lego EV3 Motor Controller

Today is the second class. We jump right into the EV3 programming. We built a classic proportional–integral–derivative controller (PID controller) step by step. The PID controller is a control loop mechanism employing feedback that is widely used in industrial control systems and a variety of other applications requiring continuously modulated control. We are able to set the target position, the robot will follow, and move the arm to that position. Because we only made the p portion, the controller will shake at the setting point. We will continue to build the rest of the controller in the following classes. All students are great helper to clean up the room. Thank you and see you next class.

Lego EV3 Motor Controller

Welcome to the second class of Lego Challenge Level IV program. Today we are explored the powerful PID motor position controller. This controlling concept is used everyday in our life, such as elevator, CD player, fan, car steering etc.  It is a little bit hard in the beginning. I will keep explain the concept and debug your program for next few classes. The final goal is to have some advanced technology for real world engineering challenges.

Intro to Lego Mindstorm EV3 and build color reader robot

Welcome to the Lego Mindstorm EV3 robot programming challenge. The first class, we built a two wheel tank drive robot for the future class. We also build a color reader robot that can scan the color, then read out for you forever. Kids are excited about. Everyone tested their robot with rubik’s cube.  The science behind it are loop, switch and color sensor. Next week we will explore the other sensor’s from lego. All students also helped to cleanup the classroom.

Intro to Lego Mindstorm EV3 and build color reader robot

Today is the first class of the eight Lego robotic programming classes. All student are excited about building the advanced Lego robots. We achieved two goals: Assemble the Lego car with two wheel drive, and taste of the color reading program. The students learned the fundamental programming loop, switch, and functional modules. They are hooked to the robot. In the next class, I will continue the exercise to make sure each student build their own color reading robot.
