Rovers can't move (brakes are off!)

[MathmoRichard]

I was just about to post victoriously about a successful base building technique in my old thread, and then whilst getting screenshots my rovers just stopped moving.

To reproduce I simply decouple the rovers and switch craft back and forth, when I get to one I'll find it can't move (and the brakes are off and they should be controllable). The wheels appear to spin a small amount and the steering works, but I just can't move. Usually only one gets stuck.

I wanted to upload a craft file but can't see how. Please suggest how I should if you want it.

I'd be interested in your .craft file. Look for it here: ...\Kerbal Space Program\Ships\VAB

[MathmoRichard]

How do I upload it on here? Or must I use another site? (suggestions?)

[jarmund]

Some quick theories:

- I don't see any power generating devices. Out of electricity?

- One wheel pair spinning the wrong way

[MathmoRichard]

Assume the rovers work 110%. They have loads of power (two big batteries, enough for a whole day of idle time at least), and in fact they respond the whole time, like I said they steer but don't move. I have test driven them and they work perfectly, they have moved that tank half way up the runway and back.

Dropbox, google drive, similar.. or any of the thousands of uploading sites

[MathmoRichard]

Here you go guys.

[MathmoRichard]

Update: can't seem to get it with similar different craft. So what's with this one?

[SpaceExplorer]

I too have had this problem before. I don't know if this is a bug, but it only effects rovers (or things with wheels on them) that have been docked then undocked with the gear button still on (and in your case you are using the claw, which acts in somewhat the same way). In order to fix this try "raising" the gear by turning off the button and see if that helps, as it did work for me.

All the best, and please let me know if that works for you.

I believe you are running into a minor bug with the brakes. Under some situations, they activate when switching around even though the icon is off.

If this is the same bug, you can fix it by simply toggling the brakes on, then back off. I can't recall if you need to click the icon to properly clear it out, of if just pressing B takes care of it.

Hopefully that will help work around the issue..

Cheers,

Didn't help

I think I've pinned it down to decoupling with a docking port only, separators never cause a problem.

This is more than just brakes...

Correction: it happens with another version, and with separators IF they are attached to a docking port!

[MathmoRichard]

I've just worked out that when it happens the craft switch loop isn't a loop, it has a beginning and end, as though it is stuck.

I've found some errors in the console. Does anyone have any ideas?

At the end of the day, I'm scared of taking these all the way to Duna or something and then they don't work.

[MathmoRichard]

Bump, just before I launch these things into space (I suppose we can edit saves if it goes wrong but I'd hate to have to do that). Sorry if I'm bugging anyone

[Claw]

Wait, are you separating both rovers at the same time?

There's also a bug with separating multiple controlled vessels at the same time from a root, non controllable vessel. Although this usually manifests itself in not allowing you to return to the space center. So possibly you might have found a variant that acts a bit differently with docking ports. I'm not sure, but definitely strange...

Cheers,

~Claw

[MathmoRichard]

Ahhh! Yes my root may be uncontrollable. Well in the craft file the root is actually a rover, but it might have ended up as the root if the original root was dumped first. I separate at different times. It's certainly some kind of bug, I just want to prevent it.

I'm having a lot of problems with my KSP right now, it's getting depressing. When I say a lot, it just occasionally ruins many hours work and no amount of quick saving can help. Does reinstalling help much?

[eddiew]

Is your plan with these doohickeys to kawl them onto the orange tank, open their outer claws, and attach other things to them? Asking because last time I read about it, having the claw on a non-active vessel (e.g. a stationary object while you drive a rover into it) will summon the kraken and kill your game ^^;

Yes it was, and I was just about to post about how whenever I time warp everything explodes.

What can I do? Will it be ok after they are separated?

[MathmoRichard]

Now I've landed the lot, so I thought I'd release the claws and hopefully the problem would just go away. After I got the sky crane back in orbit time-warping blew up the unladen skycrane but not anything else. What???

[eddiew]

AFAIK the only safe way to attach a klaw is to be in control of the vessel that has the klaw. You might be able to point the other ship at it and quickly switch focus, but I'm not sure if that's safe.

Or you may have found a totally different bug - I just remember the klaw thing from something that popped up on the forum months ago ^^;

[MinorInconvenience]

I have had the exact same problem with BahamutoD's critter crawler--I had thought it was a bug with that mod. After attaching a critter crawler probe/rover (saved as a subassembly) to a ship by a docking port and, in game, detaching it from that docking port, causes me to lose the ability to move it's legs (which I understand are just retextured wheels). The controls are still working because it rocks from torque (and I can activate it's rockets and fly it), but it will not roll/walk. Switching to the space center, switching vessels back and forth, and reloading do not fix it. I should have a save file somewhere with the rover experiencing this problem that I can upload tonight.

Ahhhh. I may have done this. I didn't do quick switching but I just flew into a claw and it captured me. This was done quite a bit to the ship in question.

Can I do anything about it by editing the file?

[Buzz Bartwig]

I fixed this problem by adding an electricity generator like a RTG or solar panels

[James Kerman]

Welcome to the forum @Buzz Bartwig.

It's really good advice but this is quite an old thread and hopefully MathmoRichard managed to solve his problem a while ago. Once I've unlocked the tech I add an RTG to all my vessels as a precaution.
