Setup and Assembly
The JIMU Robot kit utilizes a free app for detailed 3D, 360° animated building instructions. No tools are required for assembly, as all parts snap together securely.
App Installation:
- Download the free JIMU app from your device's app store (compatible with both Android and Apple smart devices).
- Ensure your smart device has a stable internet connection for initial download and updates.
Building Instructions:
The JIMU app provides interactive, step-by-step 3D, 360° animated instructions. Follow these guides within the app for precise construction of your robot. You can choose to build one of three different robots: ChampBot, BasketBot, or ScoreBot, or even invent your own custom design.

Operating Your Robot
Once assembled, the JIMU Robot is controlled and programmed via the dedicated app. Ensure your robot's main control box is powered on and connected via Bluetooth to your smart device.
Basic Movement and Interaction
Use the app's interface to drive your robot, pick up and launch the included game balls, and navigate around obstacles. The 3 servo motors and 2 DC motors allow for precise and fluid movements, while the IR sensor helps the robot avoid opponents or obstacles in its path.

Programming and Coding
The JIMU app features a user-friendly Blockly-based coding interface. This visual programming language allows you to drag and drop code blocks to create custom actions, sequences, and behaviors for your robot. Experiment with different commands to make your robot perform complex maneuvers and achieve competitive goals.
Maintenance
Proper maintenance will ensure the longevity and optimal performance of your JIMU Robot:
- Cleaning: Wipe the robot's surfaces with a dry, soft cloth. Do not use harsh chemicals, abrasive cleaners, or immerse any part of the robot in water.
- Battery Care: The kit includes a Lithium Polymer battery. Refer to the app or quick start guide for specific charging instructions. Always ensure the robot is powered off when not in use to conserve battery life. Avoid overcharging or completely draining the battery.
- Storage: Store the robot and its components in a dry, cool place, away from direct sunlight and extreme temperatures. Keep parts organized to prevent loss.
Troubleshooting
If you encounter issues with your JIMU Robot, refer to the table below for common problems and solutions:
| Problem | Solution |
|---|---|
| Robot not responding to commands | Check the robot's battery charge. Ensure Bluetooth connection to the app is active and stable. Restart both the robot and the app. |
| JIMU app not loading or crashing | Ensure your smart device meets the app's minimum system requirements (iOS or Android compatible). Try force-closing and reopening the app. If the problem persists, try reinstalling the app or checking for app updates. |
| Parts not fitting together correctly during assembly | Carefully review the 3D animated instructions in the JIMU app. Pay close attention to part orientation and connection points. Ensure you are using the correct parts as indicated in the app. |
| Robot movements are jerky or imprecise | Ensure all servo motors and DC motors are correctly connected to the main control box. Check for any obstructions in the robot's moving parts. Calibrate the motors via the app if a calibration option is available. |
