Made a robotic arm for a space station, but not sure it looks quite right. It's about the size of the European Robotic Arm, though it's inspired by the Canadarm2 and the JEM-RMS robotic arms. The "forearm" of the robot is about 4.6 m in length, full arm length is about 11 m.
Any feedback?

Looks good, it looks very robust. Perhaps you could add a camera on the end of the robotic arm to manipulate objects with precision, as in the Canadarm.

There will indeed be cameras on the arm, though I didn't think of putting them on the end effector. Rather they were going to be attached to the two hardpoints on the forearms; they would have been attached and configured on orbit, since the arm will be carried to orbit by a free-flying module.
I like the other robotic arm, but...it just didn't look right for it's size. I'm gonna scale that design down for incorporation into a smaller arm which will be with another module.
Comparison of the robotic arm, in launch configuration, with the home base module (and grapple fixture):
Comparison of the arm with a person (and a payload):
Still working on the end effector design.

After working on the end effector non-stop for literally 12 hours, and not be satisfied with any of the 10+ designs I ended up making, I just said "screw it", and did a satisfactory half-
job.
Didn't help that my computer decided to have a heart attack midway through and only autosave salvaged my work and sanity.
The finished arm:
Overall, the arm looks good IMO, but there are bad parts on it, the worst offenders being those EVA handrails and the end effectors.

And done, I think I'm satisfied with the final design:

OK, guys, stop joking about bears walking along the streets of Russian towns. It's not a freaking joke anymore. These hairy bastards are invading my city lately, there were around half a dozen of them seen walking at night through residental districts this autumn. Two were shot by police, others managed to disappear among the living quarters. When you walk at street at night and hear somebody is snuffling behind your back you can't be sure it's just a common serial killer anymore. You can't be sure it's just bums whose snoring you hear from the basement window of your building or from opened sewer access hatch. It could as well be the giant hairy beast with claws and fangs visiting the place in the search for something yummy.
This video was filmed two weeks ago, and this is not even the last case of bear invasion:

It seems bears are a problem in many places: http://www.cbsnews.com/videos/floridas-first-bear-hunt-in-two-decades/
But to be honest, when you hear a weird story, chances are pretty good it comes from Florida.

Reminds me of a deer encounter we had at one of my former workplaces. The main lobby of the building was glazed on both sides and so you could see open woods looking through the lobby from either side.
Well, Doe-a-deer-a-female-deer decided she wanted to run right through the lobby to get to the other side. She smashed through one plate glass window, getting badly cut up and disoriented in the process. Bleeding everywhere and now freaking out, she started running down a dead-end hallway, then fell down two flights of stairs, and then ran into the men's room, getting stuck in one of the stalls.
The police and animal control were called. The doe broke two legs during all this, and so the state police came in and finished it off with shotguns. Imagine letting off shotguns in a small bathroom at a freaking-out deer. What an episode of Cops this would have been!
One of the secretaries had to clean the lobby after this. She left shortly afterwards...hard to see why. :lol:

Place I worked once had a cafeteria with automatic doors to the outside. One day a buck with a big old antler rack decides to stroll in and have a look. Of course he freaked out when people came in, and nobody wanted to get near those pointy antlers.
Fortunately the buck went by the automatic doors again and let himself out before things got ugly.

Nothing like a little out-of-the-ordinary suspense to expand the mind and liven up the day. I can see a bunch of people staring at the buck, holding their lunch trays, frantically trying to process what is happening in their brains. I can also see the buck staring back at them, also frantically trying to process what is happening in its brain. Some things are so out of the normal that instinct just shrugs its shoulders and says, "Sorry...I've got nothing!".

Just this year the summer camp I annually work for had a bear problem. There was a resident group, about 3-5 individuals, that had wandered into the camp grounds and were hanging out in the woods. We think they were looking for territory because they were relatively young, but at least one of the bears had 2 tags on it's ear so I suspect it was a "problem bear".
We couldn't let the kids know, but we told their leaders about it. So whenever we sighted one we couldn't alert the other staff over radio, because the kids would hear (and freak), so we just started calling them "our big friends".
I got into some serious when I was walking alone to my work site, and I accidentally spooked some large dark animal. I immediately called over the radio about "our big friends", and when the rangers came, I directed them to where I had seen it flee. Cue them searching around a campsite, and only me noticing that a rather large groundhog was hiding under a tent platform, watching us. Then I realized what I just did. h:
The rangers were pretty cool with the false alarm, since I did what I should've done, but the other staff wouldn't let me hear the end of it for the rest of the time we had together.

I just came this close to dropping the production database on the remote desktop to the server instead of the development database on my machine :facepalm:

Random thought:
Someone posted Nena's 99 Luftballoons in the runaway blimp thread, and it made me think of good 1980s nuclear/cold war songs...
Distant Early Warning - Rush
2 Minutes to Midnight - Iron Maiden
Stand or Fall - The Fixx
Just off the top of my head. I know there are tons more. While the Maiden tune is awesome, the number of New Wave tunes (and that album was as close as Rush ever got to new wave) with really dark themes is interesting.
