Wires Pull Themselves Out
We have our camera working, but we have the problem of the PWM cables (specifically the TTL one) pulling themselves out. Any suggestions on wiring that might prevent this? Thanks!

Re: Wires Pull Themselves Out
find a place to tie-wrap the wire to something right next to the camera. The connectors are not designed to hold the weight of the cable.
those little tiewrap foam tape stick on square anchor things work great |

Hot glue gun is what we use. We hot glue EVERYTHING. PWM cables on robot controller, Victors, relays, digital I/O, analog, CMUCAMERA.....everything... And you can remove it pretty easy afterwards if you need to. - |

Im not sure exactly ho but I would guess, you would plug the PWM in. Then apply it in the crack of the victor and the pwm. Around the outside edge.

On the side of the mount there are holes, I removed the plastic casing from around the wires, pushed it through, and stuck them back in the plastic casing. Then I placed it on the board. This means they get less movement at where they are attached at the board, thus meaning they don't fall out. Then to the computer, I have it attached along the way with a tie-wrap from where the camera is positioned, so it should not fall out, if it does we have a serious problem.
Since mine is tilt only these days, I don't really have to worry about the pan causing tension, as the tilt amount is not enough to get it the cable to accidently fall out. Hot gluing anything is not what I would suggest, but if it works for you, good luck with it. |

Hot glue is actually an industry standard solution (as explained to me by an electrical engineer; it has excellent insulating properties).
If you take apart a radio, TV, etc. sometimes you will find hot glue holding vibration-sensitive parts onto the board. :) |
Re: Wires Pull Themselves Out
I dont know if its PC or even GP to come out and say this on a public forum,
but.... a robot that likes to pull out its own wires? We frown on that around here! Your robot needs professional help! :^) |

Yeah, say that hot glue doesn't burn to the scar on my left hand that I've had since fifth grade.

One of our mentors gets this orange anti-tamper stuff from his job.. We've used that for most of our robots, and never had a problem with it.

We cut the plastic casing off and carefully soldered the wires onto the formerly encased connectors, then insulated them. On the power wiring we actually pulled the connector pins, but had so much trouble getting the solder out of the plated through holes we did not try that again. Once the solder was out of the plated through holes, however, you get a really good soldering job for the cabling directly to the board. Eugene |
