huh26 Posted October 27, 2022 Share Posted October 27, 2022 This assembly here is controlled by a KAL-1000 controller. It doesn't clip when it is moving. The pistons, except for the ones with servos attached, do not move. Also, the hinge on the top left doesn't move. Is there any way to move the pistons without adding servos to them?

Snark Posted October 27, 2022 Share Posted October 27, 2022 Is it a KAL-1000 controller problem, or a problem with the pistons themselves? (i.e. a "controller software" problem versus a physical problem) For example, can you extend and retract the pistons using the PAW?

huh26 Posted October 27, 2022 Author Share Posted October 27, 2022 (edited) No, it isn't a problem with the controller. You can see the target angle going up and down, yet nothing happens - also, nothing happens when the target angle is changed manually. If the parts on top of the piston get broken off, the pistons can move. I don't know about the hinge on the top. The pistons are also a bit shaky in some cases, almost like they're trying to extend. Or maybe the Kraken is messing with me. Edited October 27, 2022 by huh26 Extra info added/spellings Quote Link to comment Share on other sites More sharing options...
18Watt Posted October 27, 2022 Share Posted October 27, 2022 Sounds like auto struts, check to make sure you do not have auto struts or rigid attachment enabled. I have experienced similar bizarre behavior using robotics with docking attachments of any sort, including docking ports and grabber units (the Klaw..)

huh26 Posted October 27, 2022 Author Share Posted October 27, 2022 (edited) Oh. Is there any way to make it less floppy? It's really hard to precisely move. Obviously auto struts/rigid won't work. It also happens to flop right through the bottom of the cargo bay. (There probably isn't any way to fix that, but it's high on the list).

First, a contraption like that would also be floppy and unwieldy in the real world. There's a lot of weight supported by hinges which are not able to handle that much mass, at least not in full Kerbin gravity. However, to make it less floppy or twitchy, I'd suggest increasing damping, decreasing servo or piston speed, and possibly even decreasing the power of the device. Also, moving that much mass around at such great distances from the pivot point is going to exert a lot of torque forces on the vessel. To keep the whole vessel from flopping around as you move the arm I'd suggest greatly increasing the mass of the ship. Perhaps add a bunch of full ore tanks. As to your original problem of having the hinges and/or pistons not move at all, just shake and twitch: Did that only happen when the grabber unit (Klaw) was grabbed onto another vessel? Or did it happen all the time? I do recall having a lot of problems with robotics combined with docking ports, but can't recall exactly what all the issues were. If that issue is (was) happening even with nothing attached to the Klaw, I would suggest rebuilding the entire arm from scratch. Sometimes a robotics part can get attached to the wrong end of something, and it ends up not able to articulate like it's supposed to. Hard to diagnose, often easier to just start the whole build from scratch. Good luck! Quote Link to comment Share on other sites More sharing options...
