Summary:

Lesson 1-7, students learn to assemble and integrate various sensors and modules with Block Coding unto OtterBot X1.
Lesson 8-10, Students utilising the knowledge they have learned to do 4 projects. And to present their solutions to the class.

Lesson 1: Introduction and Assembly of Otter X1
● Objective: Introduce the Otter X1 robot, and its components, and complete its assembly.
● Activities: Assemble the Otter X1 robot, including attaching the servo motors for walking, and connecting all electronic components to the controller.

Lesson 2: Basic block Programming and Motor Control
● Objective: Learn to program the Otter X1 robot to walk.
● Activities: Program basic walking patterns using the servo motors, controlling speed and direction.

Lesson 3: Utilizing the Ultrasonic Sensor
● Objective: Implement obstacle detection using the ultrasonic sensor.
● Activities: Code Otter X1 to stop or change direction when it detects an obstacle within a certain range.

Lesson 4: Expressing Emotions with the OLED Display
● Objective: Use the OLED display to show different emotions or statuses.
● Activities: Display simple emoticons or messages that change based on Otter X1’s interactions with its environment (like happy when a path is clear and sad when blocked).

Lesson 5: Interactive LED Displays
● Objective: Program the NeoPixel LED rings to respond to environmental interactions.
● Activities: Change the LED colors and patterns based on Otter X1’s actions, like turning red when near obstacles or green when the path is clear.

Lesson 6: Sound Interaction Using the Buzzer
● Objective: Integrate auditory feedback through the buzzer.
● Activities: Use the buzzer to make different sounds when Otter X1 starts, stops, encounters obstacles, or changes direction.

Lesson 7: Sensor Integration and Feedback Loops
● Objective: Combine all sensors and outputs for interactive behavior.
● Activities: Develop a program where Otter X1’s movements, screen expressions, LED lights, and sounds are all responsive to the environmental inputs from the ultrasonic sensor.

Lesson 8: Sensor-Based Coding Challenges
● Objective: Enhance problem-solving skills through coding challenges focused on sensor integration.
● Activities:
○ Alarm System: Students develop an alarm system where Otto detects a close object with its ultrasonic sensor and reacts by displaying a warning on the OLED, lighting up the LEDs in red, and sounding the buzzer.
○ Greeting Mode: Program Otto to recognise a “friendly approach” (a specific distance range detected by the ultrasonic sensor), leading it to display a smiling face on the OLED, play a welcoming tune on the buzzer, and light up the LEDs in a welcoming pattern.

Lesson 9: Advanced Sensor-Based Projects
● Objective: Apply learned skills to develop advanced sensor-driven projects.
● Activities:
○ Interactive Pet: Students program Otto to behave like a pet that follows its owner around, using the ultrasonic sensor to maintain a specific distance. If the distance increases or decreases beyond set thresholds, Otto changes its OLED expressions and LED colours to signal its ‘mood’.
○ Obstacle Course Navigator: Design a complex obstacle course that Otto must navigate. Students program Otto to use its ultrasonic sensor to detect obstacles, plan paths around them, and use the OLED and LEDs to indicate decision-making processes or status updates (e.g., finding a clear path or being stuck).

Lesson 10: Presentation and Peer Review
● Objective: Showcase and review peer projects.
● Activities: Each student or group presents their Otter X1 robot and its unique navigation and interaction capabilities. Certification Program.
