51 Insert all servo connectors to pins on board. At that time, be careful not to make a mistake of confusion between "R" and "L".
52
53 Please turn on the switch to make Initial adjustment of servo angles. All servo axes are rotated to initial angles.
IMPORTANT
Please use fully charged five Ni-MH batteries. If the charging of batteries is incomplete, servos does not work correctly with noise.
IMPORTANT
It's very important that you must maintain servo motor's initial position while you assemble. After you initialize servo motors along with this step, you MUST NOT change the angle of the servo motors until you complete assembly. This means you must be very careful about keeping its angle when you assemble parts around servos. Wrong angle is one of the common reasons why Rapiro goes crazy when you put the power on.
54 You did make Initial adjustment of all servo angles.
55 Insert the cable and the waist servo into the square hole of the waist part from upside to down side.
56 Then insert the cable in a side hole from downside to upside.

69 Pass through the cable further into the next hole.
70 When you finished through the both of cables, look like this.
71 Next, use the parts of the U-shaped.
72 Insert the "R foot_y" and "L foot_y". Don't turn the shaft of the servos, because it's according to the initial value of the angle. There are individual differences in the initial value of the servo motor, so sometimes it might not be completely parallel. But don't panic! It can be adjusted in the program at the end.
73 Tighten the servos with the silver screws (Tapping 3mm).
74 Look like this.
75 Next, Use the right foot part.  Be careful "right side" or "left side", when you assemble.

200 Tighten the flat head screw from the back of head.
201
202
203
204 At the end, connect the computer, and adjust the value of the angle due to individual differences of the servos.
Note: If you hear large buzzing sounds from servo motors when Rapiro stands with power supply, it's mostly because of the reason that the initial angle of servo motor on foot is not horizontal enough. In this case you can adjust the angle by folloing process so that the buzzing sounds will be ceased. You are better to be careful especially for foot servo motor adjustiment, because servo motors are not durable under strain by inproper adjustment.
You need to install these software, if you don't have.
Arduino IDE
FTDI Drivers ( How to install.)
Then download the sketch from the url below and open it with Arduino IDE.
Standard firmware for controller board (Arduino sketch)
205 The eyes parts light up when you connect the computer and RAPIRO with the Micro-USB cable, and turn on the switch to energize to the servos as shown.
206 If the arms or legs are inclined a bit when you turn on the switch,
207 Enter the correction value of the angle to the array of int trim[MAXSN]
208 Change the correction value of the servos that are inclined, then upload the standard firmware for controller board to the RAPIRO board.
Select "Arduino Uno" from tool menu when you upload the sketch.
209 Repeat the changing the array of int trim[MAXSN], and the uploading its sketch, until the posture is fixed.
210 When you have made adjustments of servos, let's send Serial Command #M1- #M9 via serial terminal of Arduino IDE. Then RAPIRO will make the motion which is assigned to the command number.
Serial Commands List
211 If you put Rasberry Pi and/or wireless communication module into RAPIRO and program them, you will be able to control RAPIRO wirelessly.
212 One of the two cushioning tray can be used to secure the assembled RAPIRO in the box.
213 The box can be used for storage, and to bring out.
