Week Four: Robotics (CS, ME, AI)

Arduino Kit: 3B.MOV

Arduino Kit: Activity 3B

This is the final result of activity 3B of the Arduino SparkFun Kit. This project shows a multicolored light bulb changing different colors based on the motion sensor. When there is detected motion within 10 inches of the sensor, the LED will turn red. When there is detected motion between 10 to 20 inches of the sensor, the LED turns yellow. Detected motion beyond 20 inches changes the LED to green.

Arduino Kit: Activity 3C

This is the final result of activity 3C of the Arduino SparkFun Kit. This project uses the same LED sensor detection system as Activity 3B, however, there is an added motor. Whenever an obstacle is detected, the motor rotates back and forth until the obstacle moves outside of the sensor's readings.

Arduino Kit: Activity 5C

This is the final result of activity 5C of the Arduino SparkFun Kit. This project demonstrates the principles of activities 3B and 3C to power a mobile robot. In this activity, wheels and a battery were attached to the underside of the car using a special velcro material. The batteries were attached to motors that connected to the wheels, giving the robot the ability to move. The sensor is used to detect obstacles in the robot's path instead of the LED sensor in Activity 3B.

EZ Bot Demonstration and Code

Our group coded the EZ bot using the switch blocks method. In our demonstration, we had our robot walk up and lock onto a face. As soon as a face was recognized, the robot stated "I see a human" and did a dance.

Zumi-ai

We used a while loop to make sure the car is constantly moving forward. With the help of the sensor, we can detect the distance between the obstacle and the car, when the distance is less than 100 units, the car will turn to one side.

Arduino Red Bot

The Arduino Red Bot was coded to follow and track a line. We use the built in library of Arduino uno board to make use of its sensor. When the sensor detect that the vehicle is away from the black line, the code can modify the speed of the wheels in order to make it turn back to the right track.

Tamiya Build

The Tamiya build combined the knowledge of all the activities done in the Arduino Kit and the Red Bot. The wiring and sensor detection system utilized in Activity 5C was replicated and rebuilt on a new breadboard. Our group constructed a mechanism that had 4 large wheels in each corner with 2 sets of smaller wheels in the middle. From the Red Bot, we replicated the bumb sensors and constructed a new motor to power the wheels.
