4. Control Robot Dog Using IR Remote

You can also control the Robot Dog using the IR remote control.

Point the IR remote directly towards the IR sensor mounted near the top of the Robot Dog head.

Make sure:

• The IR sensor is visible.
• The IR sensor is not covered by wires or Velcro.
• The remote is pointed towards the IR receiver.
• The Robot Dog is powered ON.

IR Remote Controls

IR Remote Button	Robot Dog Action
Forward	Move forward
Backward	Move backward
Left	Turn left
Right	Turn right
Stop / OK	Stop movement

Note

If the Robot Dog does not respond to the IR remote, check whether the IR sensor is connected to P2 and aligned properly near the top of the Robot Dog head.

5. Experiment with Robot Dog

After testing the basic movements, try experimenting with your Robot Dog.

Here are some fun activities:

Experiment	What to Try
Walking test	Check how smoothly the Robot Dog moves forward
Turning test	Test left and right turning movement
Obstacle path	Create a small path and guide the Robot Dog through it
Remote challenge	Control the Robot Dog only using the IR remote
Bluetooth challenge	Control the Robot Dog from the web app
Speed tuning	Modify the program to change the walking speed
Step tuning	Adjust servo angles in the code and observe the movement
Creative design	Add more colours, stickers, or a name tag to the Robot Dog

---

6. Safety and Usage Tips

• Use the Robot Dog on a flat surface.
• Do not pull the servo wires while it is moving.
• Keep fingers away from the moving legs.
• Make sure the micro:bit and expansion board are secured using the Velcro band.
• Keep the IR sensor facing forward or upward.
• Turn OFF the power switch after use.
• If the legs get stuck, turn OFF the power before adjusting them.

7. Troubleshooting

Issue	Possible Reason	Solution
Web app does not find micro:bit	Bluetooth is off or micro:bit is not powered	Turn ON Bluetooth and power ON the Robot Dog
Micro:bit pairs but does not respond	Program may not be loaded correctly	Recheck and upload the Robot Dog program
Robot Dog moves in wrong direction	Servo connections may be swapped	Check front servo on P0 and back servo on P1
IR remote does not work	IR sensor is blocked or misaligned	Point the IR sensor towards the remote
Only one servo moves	Servo wire is loose	Check P0 and P1 servo connections
Robot Dog stops suddenly	Power may be low	Replace or recharge the battery
