Introduction

Thank you for purchasing Piccorobo IoT assembled version," Thank you". This manual describes how to use the robot.

Please

read this manual and use robot carefully.

•

Please note, personal computer (PC) is necessary for operating this robot so this manual and other related documentary

instruction assume that users are familiar with at least basic level of operating knowledge about PC. Therefore, any questions

related to PC and or Wi-Fi devices themselves are out of support.

•

This product does not include battery and charger. Please buy Ni-MH AAA buttery and its charger by yourself

This product is supposed to be operated under connection to Wi-Fi

. You can also operate it out of Wi-Fi but this will cause

a part of function and sketch come to be failure.

※Please note that specification might be changed without notice due to outcome of improvement.

Cautions

●

Please make sure to keep out of the little child when use or assemble this product. Besides, please pay attention not to let the

little child swallow small parts by any occasion.

●

This product is not a toy. Please make sure to keep an eye on the site when the child touch or use this robot.

●

Do not use or store this product under a high humidity environment or place otherwise unexpected condensation may occur.

●

Please make sure to handle this product with any tools carefully..

●

Do not disassemble or remodel servo motors as well as PCB because they are precision equipment so some failure, electric shock

and fire are presumed.

●

Do not place conductive things on the PCB because there is a risk of short, broken and fire of battery and circuit.

●

This robot might cause some unexpected behavior during the adjustment. For avoiding any possible bodily injury and property

damage due to falling of this product, please keep enough space when handling it. Meanwhile, please mind your finger during every

operation with the robot..

●

When you join the connector to the PCB, check pin assignment carefully. It is risky if you make a wrong connection.

●

Please mind any possible pinching of cables because disconnection and short are concerned.

●

When disconnect the cables, please pull the portion of plug or connector. If you disconnect and reconnect by pulling the

cord part, some unexpected electric shock and or fire might be caused by disconnection and

short-circuit.

ToolsRequired

The following tools are used for expanding and modifying Piccorobo IoT. Please prepare by yourself.

02 Setup

First, you need to set up to make VS-RC202(the board) can be used with PC. Please refer to VS-RC202 manual for detailed

instruction of set up.

■

VS-RC202 Manual

https://www.vstone.co.jp/products/vs_rc202/download.html

After finishing software set up, connect the board to your PC via USB port and following instruction as below

to write sketch for adjusting axis of servo motors.

(Choose VS-RC202 sample sketch “vs-rc202_set_home_position”)

Power button

03 Control the robot

Follow sequences as indicated below to write program into the board and you may succeeding in controlling the robot gradually.

Note, an environment for accessing Wi-Fi will be necessary after you completed all following sequences..

Please keep a note of the SSID and password for the Wi-Fi router you want the robot to connect to in advance.

※Please use the 2.4GHz band.

A) Power ON

Open the cover of the robot head and set Ni-MH AA battery in the battery box and connect DC plug into DC jack of the board. And then

connect the board to your PC via USB, board will turn on and led will light.

In case of the power is ON, if the feet touch each other or spacer links hit the edge of the hole as shown below,

take off the DC plug immediately.

If you neglect such reaction, some damage to the servo motor might be caused.

If the feet touch each other or spacer links hit the edge of the hole, the servo horn is determined to be misaligned. Please

reattach servo horn to the axis of the servo motor. Little misalign is no problem but please just make sure that feet do not touch

each other as well as spacer links do not hit the edge of the hole

If the servo horn has been misaligned, please follow sequence as below to reattach it to the axis..

①Turn off the power of the board and remove the servo horn from the axis of the servo motor.

②

Turn on the power of the board after removing the servo horn (servo motor axis will be home position).

③When power is on, reattach the servo horn to the axis of the servo motor (Do not tighten the

screw).

④After turning off the power of the board, screw the servo horn.

It is OK, if no parts interfere with each other when power is ON. Go to next page.

B) Board configuration on Arduino IDE

01. Start Arduino IDE, select the Tools> Board> Generic ESP8266 on menu bar, and select other settings

below.

C) Sketch uploading

Connected the board with your PC via USB and startArduino IDE.

Select Files> sample sketch> VS-RC202> vs-rc202_HTML_Controller on menu bar and open sketch. And then select Tools> ESP8266

Sketch Data Upload and. After a while, you can see [ 100%] on Arduino IDE prompt and it means file upload finished.

If ESP8266 Sketch Data Upload does not display

, software setting has not been finished so please complete the initial settings by referring to

the "software set

up" on VS-RC202 Instruction Manual.

In this section, install HTML file which is displayed on smart phone in VS-RC202. When you want to install some files except of sketch,

use this function. If you want to know about detail, please refer to the VS-RC202 manual.

Next, upload sketch in the board. Click arrow button. If sketch is written to the board successfully, the

message “Done uploading”

would be displayed. If error message is displayed, check the board settings and port selection.

It takes for a while to upload sketch. Do not unplug USB cable until the message “Done uploading” is displayed.

D) Wi-Fi settings and servo motor adjusting

After checking sketch uploading has been done, Set up Wi-Fi configuration. You can find the line to describe SSID and password of

your Wi-Fi router near the top of the sketch. Please write SSID and password of the Wi-Fi router.

Then set the offset to correct the deviation of the servo horn. There is a function called "setServoOffset ()" to the 236 line in the sketch.

By setting

the initial position to the second argument of this function and adjust the deviation. The range of the second argument

is -500 ~ 500.

[Example]

●

setServoOffset (1, 100) // Set offset 100 to SV1(left foot)

●

setServoOffset (2, 100) // Set offset 100 to SV2(right foot)

●

setServoOffset (3, -50) // Set offset -50 to SV3(center)

●

setServoOffset (4, 50) // Set offset 50 to SV3(head)

After describing the offset, upload sketch again. When upload is done, offset will be reflected.

Change offset gradually (20 ~ 60 degrees) and modify to make robot stands straight.

Since the axis of the servo motor is little bit loose, there is a possibility that cannot be modified

straight. So just adjust that robot stands roughly straight. It is enough to walk.

E) Control robot with PC and smart phone

When you have finished the adjustment of the offset, let's try to move the robot. Open serial-monitor during connecting the board with

your PC via USB cable. Select tools>serial monitor on Arduino IDE. If error message “espcomm_upload_mem failed” is displayed, it

may be that port selection is wrong or USB cable is not connected to the PC.

Set the baud rate of the serial-monitor to 115200. When the SSID and password has been set successfully, IP address which assigned

from the Wi-Fi LAN router would be displayed on serial-monitor as below.

When nothing is displayed on the serial monitor, please press the reset button on the board.

IP address

reset

Connect smartphone (or PC) to the Wi-Fi router which the robot is connected to and launch the browser. And then Enter IP address displayed on

the serial monitor in the URL field and go to the robot controller page. If you connected your device to the Wi-Fi router successfully, you will see

the page as below. If the page is not displayed, please check and verify whether any miss typing with IP address or power of robot might be not on.

Once the HTML is displayed properly, unplug the USB cable from the board and close the head of the robot. After the second time the board will

get IP address automatically even though disconnected with the PC. If you cannot open the robot controller page, it is possible that the IP address

assigned to the board by the Wi-Fi router has been changed. In the case, check the new IP address on serial monitor again.

If you try to turn off the power of the robot manually, press button for more than 3 seconds and release it. However, power won’t

be off as long as the robot keeps connecting with a USB cable which please note.
