I have got Lynxmotion A-Pod robot , Finally I’ve done form assembling and calibration robot

Just yesterday I installed the updated Psx2 library to Arduino IDE library folder , uploaded the Psx2 to Bot Boarduino , so far every thing going fine so far .

Then I’ve downloaded the ( 3DOF-4DOF-Hex-master.zip) from get GitHub , after that I moved the folder to Arduino Library folder same as i did to Psx2 file .

Then The folder name (3 DoF Ready ) which is inside the BotBoarduino folder , I’ve changed the folder name from (3 DoF Ready ) to ( (BotBoarduino_CH3R_PS2 )

Then i opened Ardiono IDE software , then upload the (BotBoarduino_CH3R_PS2 ) to my Bot Borduino , uploaded successfully.

Turned on my ps2 controller , then i pressed start , when i click any button i can hear the (peep ) sound , But the problem that the robot is not moving

Can you Please tell me if i did any mistake in uploading files process or in wires connections ???

Note : I changed the Ps2 receiver connections which are ( Data, CMD, ATT, CLK ,5v,GND) to pins number ( 10,11,12,13) in Bot Boarduino and Pin 8 ( red wire ) in Bot Boarduino goes to RX in SSC32u , Pin 9 ( yellow and Black wires ) goes to ( TX and G ) in SSC32u .
pin 8 ( red wire to RX in .

And modify these Pins in ( Hex_Cfg.h ) file

//--------------------------------------------------------------------
//[Botboarduino Pin Numbers]
#ifdef BOTBOARDUINO
#define SOUND_PIN 5 // Botboarduino JR pin number
#define PS2_DAT 10
#define PS2_CMD 11
#define PS2_SEL 12 // On the PS2 receiver this pin may be called ATT (attention)
#define PS2_CLK 13
// If we are using a SSC-32 then:
// If were are running on an Arduino Mega we will use one of the hardware serial port, default to Serial1 above.
// If on Non mega, if the IO pins are set to 0, we will overload the hardware Serial port
// Else we will user SoftwareSerial to talk to the SSC-32
#define cSSC_OUT 8 //Output pin for Botboard - Input of SSC32 (Yellow)
#define cSSC_IN 9 //Input pin for Botboard - Output of SSC32 (Blue)
#endif

#ifdef BOTBOARD_ARDUINOPROMINI
#define SOUND_PIN 11 // Bot Board JR pin number (with Arduino Pro Mini plugged)
#define PS2_DAT 14
#define PS2_CMD 15
#define PS2_SEL 16
#define PS2_CLK 17

Please use the default settings found here.

The pins 12 & 13 must be used for the software serial communication as they have a special property that the other pins do not have on the BotBoarduino (Arduino Due-compatible). Therefore, using the other pins may not work, as you have noticed.

thank you for replying

I followed the guide and and the way of connecting wires recommended between ( ps2 receiver, Bot Borduino and SSc-32u ) , but I still have the same issue .

when I press start Button on PS2 controller i can her the ( peeping ) from Borduino
but the servos which are connected to SSC-32u , not respoding , the servos are working fine when I connect the SSC-32u USB to my PC and use FlowBotics for Calibration .

But when I connect the Bot Boarduino USB port to my PC ,
the Boarduino turned on , but the servos not responding when i press any button on PS2 , just hearing the peep

One more issue that I noticed , When I changed the jumper from USB to ext on boarduino ,
and Attach the ( 9 volt ) battery , D4 D3 ,D6 and Pwr LED lights are OFF and the Ps2 receiver
OFF as well only the TX LED is ON (steady) , when I change the jumper to USB and connect to my PC all lights are ON .

Do i need to change the or remove any of the jumpers , or change the Buad on SSC-32 ,
or it’s a matter of updating the SSC-32 firmware , or even wiring connection are wrong .

In the Attachment pics of ( Bot Boarduino , SSC-32u , PS2 ) connections .
the youtube link shows exactly my connections : youtube.com/watch?v=chUCGl0fWZg
as well Attachments pic
kindly advice me what to do , i want my robot to move , I’m fed up from checking manuals and guides for almost 3 weeks :cry: .

Hi,

The wiring seems good, as before.

Since the SSC-32U is responsive when calibrating and the BotBoarduino buzzer beeps when start is pressed on the controller, then the baud rate must be wrong for the hexapod configuration.

Please check the SSC-32U manual (pages 34-35) and update your SSC-32U’s baud rate to 38400 (red LED on only). This should allow proper communication between the BotBoarduino and SSC-32U.

Sincerely,

Just updated the Baud rate to 38400 ( Red LED (B) ) , after 5 seconds both ( A,B ) green and red became On ( steady) … but still the same issue no servos moving .

May be it is a matter of updating the SSC-32u firmware . can you send me the latest firmware link

The SSC-32U already has the latest firmware (2.50USB) from manufacturing, so there is no need to update.

Please connect your SSC-32U by USB to your computer and use our free diagnostic tool, Lynxterm, to connect to it. Make sure to go in SETUP on the top left to change the COM port and baud rate.
Once connected, type in the black text box “VER” followed by [return]. The SSC-32U should answer with its firmware version.

You can also use the slider on the right to control servomotors that are connected to the board. Try some out and see if they move properly.

Let us know how this works.

Sincerely,

HIIIII Schartte Goooooood news

Just 30 minutes back I solved the issue and the A-pod servos was moving Greaaaaaaaaaaaat .

It was a silly mistake ,actually was not my mistake ,but a friend of mine who modified the ( TX,RX,GD) extender cable from Bot Boarduino side

I found that the the guy whenen he modified the ( red wire ), he did not pull up the head ,he cut the red wire and attached a new [font=Verdana][size=2]female connector to it , and left the original metal head inside with the ( yellow and balck heads ) , so the new modified red wire which is connected to pin number 12 on Bot Boarduino was inactive because of that piece of metal left inside , all connectors on pin 13
( yellow , red (metal head only ), black) were active , so the signal on pin 12 was blocked :confused: .

Another issue I solved , which was the no power goes from 9v battery to bot Boarduino , I realized from in the new SSC-32u no need for 9 volt battery to power it with Bot Boarduino , just have to connect ( VL + - ) from Bot Borduino to ( VS2 + - ) on SSC-32u , and from ( VS1 ) cabled goes to the 6 volt NiMH Battery .

Thank you Scharette for your support , sorry for troubling you :blush:

[/size][/font][size=2][font=Verdana]Just one more thing that I need your help for . The Arduino file that you created (3DOF-4DOF-Hex-master) working great
but it for 3 Dof and 4 Dof in general , I’ve got the (A-pod ) which has extra 5 servos 3 for the[/font][/size][size=2][font=Verdana][font=Verdana][size=2]mandible and 2 servos for the Tail , how to Modify the Sketch to make those servos working and controlled by PS2 as shown Step 17 in the old version tutorial
[/size][/font]

I know basic Programming , wish to be expert one day as you are :slight_smile:

We are glad you were able to solve those issues.

Indeed, the SSC-32U and the BotBoarduino can all be powered by the 6 V DC battery pack directly (no 9 V battery needed anymore, in most cases).

Concerning the movement of the head/tail, we do not currently have BotBoarduino code available for this. You would need to modify the code yourself to add that functionality. Of course, this is not a trivial task. Two people who would know more about this are the creators of the original code and the translation to Arduino of it; KurtE and Xan:

thank you very much for your help

I will contact the guys
