Since we spoke on the phone I was able to test the robot with standard Sony brand tethered dual shock 1 and dual shock 2 controllers. Well actually Laurent tested it. You may want to try turning the controller (hand held part) off then back on. He also found that no program on the bot board is even required to get the Lynxmotion controller and receiver to sync up, (lights on steady). Just batteries in the controller and 5vdc on the receiver. So if the controller worked at home, but not at work, it’s looking more and more like RF interfearance. Hope this helps.
Hey Robot Dude,
I tried the controller (PS2) wireless outdoors and still no luck. I then tried it with the PS2 cable direct and had no response either. I retried the direct serial port cable to PC connection and again it sort of worked but had very erratic movements.
Everything I see looks ok, except maybe the Atom chip needs to be pushed in a little more. That’s not your controller connection problem though.
Questions, does the robot stand and cycle through it’s leg lift sequence when powered up? If so then this must be just a bum PS2 controller. I would take the robot and the controller home and try it there. Try the normal tethered Sony brand PS2 controller on the robot too. Try the LM controller on the game console and take note if the blinking LED’s light up solid. I’ve never seen one of these controllers work on the game console, but not on the robot. This is a mystery… Let me know the results and we will make a decision on the proper solution.
Thanks for the link to upload them that was very helpful. Yes, I didn’t want to have anything overlooked - hence the pictures.

A: Unfortunately, on one side of the chip the teeth have a bend to them and I don’t want to force/break it.

A: Ok.

A: Yes.

A: I did try it out with the PS2 at home with the receiver receiver connected to the PS2 station. It worked well even with the vibration option - no problems there.

A: Yes, tried this but still no communication between the PS2 and the receiver/robot.
Try the normal tethered Sony brand PS2 controller on the robot too.
A: Yes, tried this also, but couldn’t get any response at all.
Try the LM controller on the game console and take note if the blinking LED’s light up solid.
A: Yes, one blinks continuously (left side), right side stays steady when plugged into the robot - I let this try to synchronize for over 30 minutes each time but no luck. When plugged into the PS2 station both lights go solid red (no blinking) and synchronized almost immediately .

A: Yes, please let me know, I really am interested in having this robot up and running.
The receiver module derives it’s power from the black and yellow wires which plug into the I/O bus. This bus gets it’s power from the power jumper where you can select 5vdc or VS. These jumpers can be bad. I have seen it a few times in 12 years. Please try swapping one from another location to see if it has any effect. My thinking is if the jumper is defective the receiver module my be getting it’s power from one of the other I/O pins connected to it. It can happen, and it’s always accompanied by weird behaviour. I’m really not sure what’s going on. The PS2 controller works on the game console and the RED leds light up steady then I don’t believe sending a replacement will fix anything. If you have a volt meter can you verify the 5vdc output is up to voltage and steady?
Good points (I had actually thought this might be it also). I went ahead and tried that by changing each jumper and with each swap I retried the LM controller until eventually each jumper was replaced with a new one and again the controller was tested with each case. I previously tested the power between the SSC and mini boards and this was fine. I have not checked the power after the regulators on either the SSC or the mini and I won’t be able to do this until tomorrow night at the earliest (to see if there is the 5VDC steady).
I agree with you that a replacement LM controller won’t be needed since it was verified operational with a PS2 station.
Well I have another thing for you to try… Remove the four connector end of the PS2 cable from the bot board. Now the only thing connected is the black and yellow wire for power. See if the receiver and remote will sync up now. If so you may have a bad PS2 cable. Maybe a couple wires are shorted preventing it from operating normally… It’s an idea.
Not to add insult to injury, but after looking more closely at your images I see you have made some errors on the legs assembly. Looking at the top down image of the robot the leg pointing 9:00 is perfect. As is 7:00 and 11:00. However 1:00, 3:00 and 5:00 all have the horizontal servos in backwards. The servo and bracket need to be changed. The hip up/down servos need to be reversed as well. The two knee servos that you can see are correct though. I can’t tell about the 3:00 knee servo. This explains the weird walking motions you were seeing under serial control.

A: Tried this, no luck the lights remain as previously without change and the LM controller and receiver still are not syncronizing. Actually, I previously thought this might be an issue and tested the wires for shorts etc, but everything checked out normal previously.

A: Yes, you’re absolutely correct - thanks for spotting this! Not a problem, and I made the changes accordingly.
4.97vdc is perfect. This is not the problem. We are sending you a PS2 Cable and A PS2 controller tomorrow. Let me know if these help at all. Sorry for the troubles you have been having.
Received the replacement parts, and installed them. Turned on the robot and LM Wireless Controller - WOW - the robot worked right away and extremely well!! - very impressed.
Again, I appreciate your assistance and am very impressed with the robot.
Weird, the controller worked on the PS2 console but not on the robot. Well it’s a new one for me. I’m glad you got it going! Don’t forget to post images or videos as you modify and improveyour robot!
I’m having the same problem… I’ve read through this thread for a solution, but to no avail. My unit doesn’t link up even when installed in my PS2. The batteries in the controller are brand new, so I know that’s not the problem.
We are here. Tomorrow starts the shutdown. Send me a PM with your order number and your address. I can’t guarantee it will leave today, but we will try.
