1. Introduction
The Teach Tech KC3 Keypad Coding Robot is an innovative, hands-on educational kit designed to introduce young learners to the fundamentals of robotics and coding. This unique build-it-yourself robot allows for the creation of three distinct configurations: the Doodler, Shooter, and Sweeper. All programming is done directly on the robot's integrated keypad, requiring no external devices. The KC3 promotes critical thinking, problem-solving, and STEM skills through engaging, interactive play.
2. Safety Information
- Adult Supervision: Recommended for children aged 8 and up. Adult supervision is advised during assembly and operation.
- Small Parts: This kit contains small parts which may pose a choking hazard for children under 3 years of age. Keep out of reach of infants and toddlers.
- Battery Safety: Use only the specified battery type (4 x AAA). Do not mix old and new batteries, or different types of batteries. Insert batteries with correct polarity. Remove batteries if the robot will not be used for an extended period.
- Moving Parts: Keep fingers, hair, and loose clothing away from moving gears and wheels during operation.
- Eye Protection: When operating the Shooter robot, do not aim at eyes or face. Only use projectiles provided with the kit.
3. Package Contents

Key Assembly Steps:
- Prepare Components: Carefully detach all pieces from their frames using a diagonal cutter. Smooth any rough edges.
- Gearbox Assembly: Assemble the two gearboxes according to the instructions. These are crucial for the robot's movement.
- Battery Module: Install 4 AAA batteries into the battery module, ensuring correct polarity.
- Keypad Module Integration: Connect the keypad module to the main robot body. This module serves as the brain for all coding commands.
- Choose Configuration: Decide whether to build the Doodler, Shooter, or Sweeper, and follow the specific assembly steps for your chosen model.

5. Operating Instructions
The KC3 robot is programmed directly via its integrated keypad. No external computer or smart device is needed. The robot can be programmed to move and rotate in 8 different directions.
Basic Coding with the Keypad:
- Power On: Locate the power switch on the keypad module and turn the robot ON.
- Enter Commands: Use the numerical and directional buttons on the keypad to input a sequence of commands. Each button corresponds to a specific action (e.g., move forward, turn left, specific number of steps).
- Execute Program: Press the 'Run' or 'Execute' button (refer to the manual for exact button label) to make the robot perform the entered sequence of commands.
- Clear Program: To enter a new sequence, clear the previous program using the 'Clear' or 'Reset' button.
Robot Specific Operations:
5.1 Doodler Robot
The Doodler robot is designed to draw patterns. Insert a marker pen into the designated holder. Program the robot to move in various paths to create unique drawings.

6. Maintenance
- Cleaning: Wipe the robot's surfaces with a soft, dry cloth. Do not use harsh chemicals or abrasive cleaners.
- Battery Replacement: Replace all 4 AAA batteries when the robot's performance diminishes or it fails to respond to commands. Ensure correct polarity.
- Storage: Store the robot and its components in a cool, dry place away from direct sunlight and extreme temperatures.
- Component Check: Periodically inspect all connections and moving parts for wear or damage. Replace any broken components if possible, or contact support.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Robot does not power on. | Batteries are dead or incorrectly inserted. | Replace batteries with new ones, ensuring correct polarity. Check power switch is ON. |
| Robot does not move or moves erratically. | Incorrect assembly; gears are not meshing; program error; low batteries. | Review assembly instructions, especially gearbox. Re-enter program carefully. Replace batteries. |
| Keypad commands are not registering. | Loose connection to keypad module; keypad malfunction. | Check all connections to the keypad module. Ensure batteries are fresh. |
| Doodler/Sweeper/Shooter mechanism not working. | Mechanism not correctly attached; specific command not entered. | Verify the attachment of the specific mechanism. Ensure the correct command for activation is part of the program. |
