Just set the %PRIORITY directive when compiling your Karel code. The higher the number, the lower the priority. 100 would place it pretty low.

Does your robot have the continuous rotation option?
If not, you can set the axis limits very high, and dynamically remaster once complete with your spin. This is the hacky way to do it though.
I did use the DH Matrix for defining the arm, but I don't really use it for solving, besides pulling values for link lengths and stuff like that.
Here is a playlist on one:
Mr Chris Annin goes over how he derived his IK here:
8 parts to his.
When i have the rotation matrix XYX of my spherical wrist with the offset from my axis 5 (WP) to axis 6 as the input vector what do i need to do with the output vector. Getting it in the base frame and then adding the vector to the TCP?
I'm not sure I am following you here. Typically you have a point in space as your input, and as your output you want to see if it has a solution, preferably reachable.
For my code, I input the desired destination point, then using the point, get back to where the wrist center would have to be located.
Matrix<double> wristCenter = uFrames[uframe] * commandedPostion * uTools[utool].Inverse() * facePlateInverse;
In the above, I take whatever frame the point is defined in (identity matrix if world), times it by the point given (now I have the point in world), times it by the inverse of whatever TCP the user wants to get to that point with (now I have the point where the faceplate would have to be), and then times it by a fixed matrix defining the distance from the faceplate to the center of the wrist.
Using the XYZ components (column 4, row 1, 2 and 3) of that matrix allows you to solve for J1, J2, and J3, and then once you have those, you can then solve for J4, J5, and J6, which are in the rotation portion of the matrix.
We go over IK calculations a bit in my thread, starting here.
You are almost there. I go over how my IK calcs work in this post. Its a broad 1000 foot view, but maybe it will put you on the right path.
How are you accounting for unity's weird left hand coordinates? Most (all?) industrial robots are in right hand coordinates. How do you handle the conversion?
I usually just save off the module I modified in the virtual controller (right click on the module in the tree, save as), and then just load it when I am connected to the real control, I load it in (right click on the task, and load module, once you have write access).
I think you could, but I typically just save the module I modified and load that in.
I just did this on a job. You just have to download the 5.16 roboware, unzip it and install it. Unfortunately robotstudio doesn't install it for you when you download it from the addins tab.
Once installed, you will be able to create the virtual controller. 5.16 can load a 5.15 backup.
I would chose a fixed width font. Dealing with kerning would be a pain to deal with.
What gets sent, and what gets received, exactly? Sounds like a big endian vs little endian problem.
While that works... It is like having a hangnail, and solving the problem by cutting the finger off. I like keeping DCS enabled, but safety comms disabled, so I can verify paths against existing DCS zones.
When you created your robot, did you select the line tracking option? It likely won't show up without that option on the robot.
Also, I messed up, it would be adding a "line" at the top fixture level. Not under a fixture.
That cell is a line tracking cell. Doing it with external axis, or digital interface is the wrong way to do it.
You will have to add a fixture, then under that, add a line (shown as conveyor in my picture below), then add a link, which will act as an encoder to the robot controller, which you map in the link properties.
Then in the controller, you define what type of tracking is being done. In the case of your video, circular on one of them, and line on the other.
You then use the conveyor toolbar to jog it.
DCS is complaining because it is not getting those signals from a safety PLC.
You will have to disable DCS, or disable the SAFEIO mapping in the DCS menu that is driving those faults.
In SAFEIO it would be a CSI bit, but which one depends on how it is mapped. The CSI bit would be mapped to a SSO bit, so look for what is driving those.
You can, but you don't have to, you can toggle it from the system vars page.
They are not accessible from the teach pendant. You will have to write them offline as a .ls file, and then load that into the robot if you have ASCII upload, or compile it with roboguide if you do not.
That is one of the quirks with using that variable. I only use it for outputting single step status. Never writing to it, as I've had the same issues as you are seeing.
I usually just setup the system to turn off single step when the robot is fired up in auto, by using the production check under program select under the setup menu.
You can master the axis at a value other than zero. I would just mark the axis in question with a label of where it is when the marks line up.
As someone who has written a couple of company robotic programming standards, and implemented many more, I've never seen something like that.
Most customers like having the bulk of their motion path in a single program, separated by process, or part, but a program per motion? That would be a pain in the ass. I imagine it would destroy the motion planner's ability to look ahead. The path would be very jerky.
I would like to read these standards that these mechanical engineers are referencing. Might be good for a laugh.
Is this a homework problem? What have you tried?
Also, you are missing a dimension.
