When Rapiro is turned on, Rapiro doesn't act or acts strangely.
Power supply might be not enough. Please refer to the information of power supply.
When Rapiro is turned on, the legs are not holizontal, the arms are up or waist is twisted.
You might not have done the initial adjustment of servo angles. You can see how to do it on #53 of the assembly manual. If you didn't do it, you need to disassemble Rapiro and start assemble from the process of #53.
When Rapiro is turned on, servo motor makes buzzing sounds.
You might not have done the adjustment of the angle of the servo motor's axis. You can see how to do it on #204 of the assembly manual.
The servo motor still makes small buzzing sounds even after adjustment.
Buzzing sounds could be small enough so that you are not to be annoyed by the sound. But it's not easy to remove the buzzing sound completely.
PC doesn't recognize Rapiro controller board.
Some micro USB cable is designed for recharging cellar phones. Those are made only for power supply. Please use USB cable which has ability of transferring data.
When some modules on Raspberry Pi, Raspberry Pi is turned off.
If some modules like camera, WiFi, bluetooth or so on, were attached to Raspberry Pi and power was supplied by GPIO from Rapiro controller board, power supply might not be enough to run Raspberry Pi. In this case, you might want the Raspberry Pi to have different power supply other than the GPIO.
Rapiro is not working correctly with Raspberry Pi.
If Raspberry Pi is connected to Rapiro controller board via GPIO, you might want to disable the serial console of Raspberry Pi. There is script to disable serial console for instance.
Getting an error when uploading sketch to Rapiro connected to Rasberry Pi.
If Raspberry Pi is connected to Rapiro controller board via 6-pole cable, and you want to upload a sketch to Rapiro controller board, you need to turn off the power supply for Raspberry Pi. This is done by turning off the switch on the back of Rapiro, if the power supply for Raspberry Pi is come from Rapiro controller board.
Screws are tight.
To prevent stripping damage, you need Phillips screwdrivers of #0 and #1.
If you are receiving an error "stk500_getsync() not in sync resp=0x00" when upload your sketch to Rapiro.
Please make sure that you installed the FTDI drivers, selected Arduino UNO,and selected correct Serial Port number.
