Hi, I am new to the robot kit world and I bought a lynx 6 last week because I have always had an interest in robotics.
I managed to build the arm with no problems and mounted it on a plywood base.
I installed the RIOS software on my desktop computer, connected it with a serial cable and powered the SSC-32 through the VS1 using the 6v adapter recomended by Lynx, the computer found the arm and I was able to reset the servos to 1.5ms.
The arm then went a bit jumpy and then went limp, i noticed the green light D1 was off, i wiggled the adapter connection to the SSC-32 and the green light came on again but there was no life in the arm and the RIOS software could not find it.
I tried disconnecting and reconnecting everything but to no avail. I thought maybe my desktop computer was a bit dodgy because it always crashes so I bought a serial - usb cable and installed the software on my laptop, it still does not connect.
I have read through all of the forum to find if anybody else had this problem, there was one guy but he had the jumpers on the wrong way.
This doesn’t seem to be the problem for me because I matched all of the jumpers up with the photo somebody had posted.
I am trying to connect through COM port 3 because that is the only one that it lists for me and I don’t know how to select another one. My laptop has 2 usb ports but it doesn’t change the COM port when I change usb ports.
The green LED on the SSC-32 is not a power LED, but a status indicator. It’s job is to light up when power is applied, and turn off after it has received serial data. Then it blinks when receiving serial data.
So the question is does the green LED ever go out? If yes then the PC is talking to the SSC-32. If it does not go out then the PC is not talking to the SSC-32.
The first thing you need to do is attach the 9vdc battery clip to the VL terminal on the SSC-32 and remove the VS=VL jumper. This will isolate the servo power supply from the logic supply. It should fix the first problem you were having with the desktop machine.
Ok you said that if I put a 9v battery on the VL that would power the SSC32 and the mains adapter would power the servos.
The servos twitched when I plugged the cable in, I do not have lynxterm. How do I get it? Would that work?
All of my previous post was on the desktop pc.
To make it clearer, I have a 6Vdc adapter connected to VS1 and a 9V battery connected to VL with the VL=VS jumper removed. I have the SSC-32 connected to my pc with a serial to serial cable.
I have checked all of the rest of the jumpers and they seem to be in the correct positions.
Lynxterm is a free download in the software section. It’s a simple terminal program with some added features. RIOS is fine for testing though. I have read through all your posts and am at a loss as to why it would work, then suddenly stop. Do you have installed, or have you used another application on the PC that uses the serial port? If so you may need to close or remove the application. Have you checked the device settings to see if it’s reporting errors?
Well If I recall correctly, when it was working I noticed that the gripper and the wrist were on the wrong servo pins so I switched them round but I carelessly put the gripper servo on #5 but missed the earth pin and had it connected so the black wire was on VS1 and the red wire was on PULSE and the yellow wire wasn’t on anything!
You have a short on there somewhere. Please don’t connect any more batteries. I really need to see the board as it is wired right now. Link me to an image when you can.
Getting confused here. Can you please go into more detail?
