Insert the neck into the body and bend the knees to natural angles. Drag the curly wire from the knee side to the shoulder side to avoid squeezing when the knee joints rotate. Put the joints into the following posture before turning on the power.
Long press the battery's button for 2~3 seconds to power on/off. Unplug the insulation sheet of the infrared remote's battery, then you can control Bittle X to move. The robot will keep pausing its movements with beeping sounds when the battery is low. Then you need to charge the battery with a 5V USB Type-C cable. Considering safety, the battery won't supply power during charging.
If your Bittle X's lower leg is in the right direction but doesn't move when calibrating, you may rotate it in the right direction. You should feel moderate resistance until the joint locks at the right position. The cause is that the new gears are a little too tight and the large bootup resistance will trigger the protection algorithm. The servo will reduce the force on the joint to avoid overcurrent, which will stop the joint from moving.
Buzzer beep meaning:
Sound type | Occasion | Explaination |
|---|---|---|
Short melody | Power on or reboot | The program starts successfully |
Short beep | During use | The program receives a command |
Repetitive melody | During use and pausing the movements | The battery is low or unconnected |
You can skip Chapter 3 Board Configuration and Chapter 4 Calibration. Go to Chapter 5 Play with BittleX directly.
The pre-assembled Bittle X is only coarse-tuned. You still need to calibrate Bittle X's joint servos and final assembly to fine-tune its joints for the best performance.
Friction plays an important role in dynamic balancing during walking. Though the silicone toe covers (socks) can improve grip, they will also amplify the differences of the unpredictable surface of your test environment. So for regular use, we recommend running BittleX without the socks, unless you can tune the gait or need friction to perform some specific tasks.
