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.
76 Combine the right foot part and U-shaped part as shown.

101 In the arm parts, use the small servos. Attach "R shld_r" and "L shld_r".
102
103 These are the sholder parts.
104
105 Servos have a slight individual differences of initial angles.Therefore, you may be not able to install shoulder parts horizontally.
In such a case, you can install the shoulder part to be a roughly horizontal angle. And if anything, You should install shoulder parts to be inclined behind its back. So, you can make adjustments by program via Arduino IDE later.
106 Use the thinner silver screws (Tapping 2-5mm).
107
108

173 Secure the battery box using a silver tapping screw (3mm). Please note that you don't have to fully screw in the hole, stop screwing at the depth as shown in the picture.
174 Close the breast part on the body parts. The cable between the body and the arm should be long enough as shown in the picture.
175 This cable should be long enough to move the arm freely.
176 Screw the breast part on the body parts with four black tapping screw (2mm by 7mm long).
177 If there is a gap between the breast part and the body part, some cables should be caught in the parts. Remove the breast part and check the cables.
178 If no cables are caught in the parts, there should be no gap between the parts.
179
180
181
182 Tighten the shaft with the thick silver screws (Tapping 3mm).
183 Looks like this.
184 Next, assemble the face parts.

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 Rapiro main 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 Rapiro main board to the Rapiro main 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.
