			<description><![CDATA[Good day,<br />
we are currently learning how the curve following module works for blade cutting. <br />
<br />
We want to cut a rectangle with a blade meaning the toolpath need to retract and reorient between cuts. We have tinkered with the curve following parameters a bit to see if this is possible but the generated path is not wat we intended.<br />

<br />
<br />
We managed to edit the generated path instructions so that it behaves as intended but this is not feasible for more complex paths.<br />

<br />
<br />
Is there a way to generate the toolpath automatically just by tweaking the curve following project parameters?<br />

			<description><![CDATA[RoboDK contains the XarmAPI version 1.1.5 (which I believe is really 1.15.0 from Github... <a href="https://github.com/xArm-Developer/xArm-Python-SDK" target="_blank" rel="noopener" class="mycode_url">https://github.com/xArm-Developer/xArm-Python-SDK</a>).  I need to update this to version 1.18.0 (latest version).  The reason for this is my gripper I have (uFactory Gripper G2) is not supported in the 1.15 version, but only from 1.16 and above.<br />
<br />
Also, I can't seem to get my custom gripper I created (mechanism model mechanism) to work right.  It works fine in the animation, but it will not actually open or close on the robot.  When I open the gripper to 80 (0 is closed) the robot joint 1 moves 80 and the gripper does nothing.<br />
<br />
How do I get this custom 2 finger gripper I created to actually run on the robot?  Any help would be appreciated.<br />
<br />
Thanks!]]></description>

			<description><![CDATA[Hello, <br />
First of all thank you so much for the RoboDK software it's the best OLP software I have ever tried ! <br />
I am working on a project that aims to weld bicycle frames in France. <br />
I am having trouble with finding all the right parameters for Curve follow project and external axis optimization, but I think I have found the right proportion for the welding path I want to achieve. <br />
My problem comes from the avoid collision algorithm for which there is a +-180 degrees on the Z axis of the tool. <br />
You will find attached the RDK file with the cell.<br />
<br />
The first CFP which does exactly what I need, great algorith with the weight by the way very intuitive !<br />
The second CFP which should avoir collisions turning the tool +-180 degrees and doesnt converge to a solution. <br />
<br />
The third is a manual program I did using joints target from the first CFP programm and manually adjusting the orientation of the torch on the last points to avoid collision. <br />
<br />
Is there something I have done wrong in the parameters ? Did I not understand what avoid collisions does ? Is there a better way to achieve the result from the 3rd program ? <br />
I would love to have your insights and advice on this problematic ! <br />
Thank you so much <br />

			<description><![CDATA[Hi, guys, does anyone know how to make a variable speed of movement of TCP within one layer - for example, on specific edges or sides of object I would like one speed, on the opposite sides - another speed on the sides, that are connecting these edges I need speed that is changing from the beginning point A to end point B for example, I start slowly, 250 mm/s then GRADUALLY increase to 500 mm/s then continue that speed and then backwards gradually reduce speed from 500 mm/s to 250 mm/s. Ideally, to find some instruments that adjust this gradient depending on the initial parameters: for example, for layer height (or distance between curve layers) we set one speed and they it changes it changes it automatically. <br />
I attache the input data what we had as initial curve and what we got when we have 3D printed it MANUALLY changing the speed from 250 mm/s (where you see 10 mm thick layers) to 500 mm/s where you see 4 mm thick layers. The transition is not even because we just pressed the button 50% of initial speed on the FlexPendant :)) <br />
Any ideas, help is appreciated.<br />

			<description><![CDATA[I am using a Techman TM7S to dispense glue using remote TCP. However, I noticed that there was a large discrepancy between real life/TMFlow and what was shown on the simulation. For example, I jogged the robot so a known point was concentric with a CNC milled hole, and level with the table. Then, I compared the joint angles and flange position in real life with RoboDK. I have also attached photos of the situation as a .zip for your understanding.<br />
<br />
This situation is captured in the RDK file I attached, and my goal is to make the RoboDK flange position and TMFlow flange position as close as possible.<br />
<br />
Joint position (same for both RoboDK and TMFlow controller):<br />
[3.530000, 19.860000, 134.880000, 27.370000, -88.410000, -179.450000]<br />
<br />
RoboDK end flange position:<br />
<span style="font-size: medium;" class="mycode_size"><span style="color: #000000;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">[<span style="color: #c82613;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">377.529</span></span>, <span style="color: #0c882a;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">-128.543</span></span>, <span style="color: #0c64c0;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">51.950</span></span>, <span style="color: #c82613;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">92.109</span></span>, <span style="color: #0c882a;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">-0.491</span></span>, <span style="color: #0c64c0;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">91.921</span></span>] </span></span></span><br />
<br />
TMFlow controller end flange position:<br />
<span style="color: #000000;" class="mycode_color"><span style="font-size: medium;" class="mycode_size"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">[<span style="color: #c82613;" class="mycode_color">376.04</span>, <span style="color: #0c882a;" class="mycode_color">-129.14</span>, <span style="color: #0c64c0;" class="mycode_color">50.51</span>, <span style="color: #c82613;" class="mycode_color">92.49</span>, <span style="color: #0c882a;" class="mycode_color">-0.89</span>, <span style="color: #0c64c0;" class="mycode_color">91.95</span>]</span></span></span><br />
<br />
How could it be that the joints are the same, but the end flange positions are so different? I estimated that the discrepancy was because of the difference in DH parameters. When they make the robot, Techman does a factory calibration so their simulation in TMFlow is accurate. So, my goal is to have a model representative of this factory calibration in RoboDK.<br />
<br />
To start I used the command "get kinematic signature" while connecting to the robot, which produced the following:<br />
<br />
<span style="font-size: medium;" class="mycode_size"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font"><span style="color: #000000;" class="mycode_color">D_Theta,D_Alpha,D_a,D_d,</span><span style="color: #e82a1f;" class="mycode_color"><span style="font-weight: bold;" class="mycode_b">D_Beta</span></span></span></span><br />
<span style="color: #000000;" class="mycode_color"><span style="font-size: medium;" class="mycode_size"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">Joint 1: 0.0000404,0.0179395,0.0165720,0.0000000,-0.0000246</span></span></span><br />

			<content:encoded><![CDATA[I am using a Techman TM7S to dispense glue using remote TCP. However, I noticed that there was a large discrepancy between real life/TMFlow and what was shown on the simulation. For example, I jogged the robot so a known point was concentric with a CNC milled hole, and level with the table. Then, I compared the joint angles and flange position in real life with RoboDK. I have also attached photos of the situation as a .zip for your understanding.<br />
<br />
This situation is captured in the RDK file I attached, and my goal is to make the RoboDK flange position and TMFlow flange position as close as possible.<br />
<br />
Joint position (same for both RoboDK and TMFlow controller):<br />
[3.530000, 19.860000, 134.880000, 27.370000, -88.410000, -179.450000]<br />
<br />
RoboDK end flange position:<br />
<span style="font-size: medium;" class="mycode_size"><span style="color: #000000;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">[<span style="color: #c82613;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">377.529</span></span>, <span style="color: #0c882a;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">-128.543</span></span>, <span style="color: #0c64c0;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">51.950</span></span>, <span style="color: #c82613;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">92.109</span></span>, <span style="color: #0c882a;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">-0.491</span></span>, <span style="color: #0c64c0;" class="mycode_color"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">91.921</span></span>] </span></span></span><br />
<br />
TMFlow controller end flange position:<br />
<span style="color: #000000;" class="mycode_color"><span style="font-size: medium;" class="mycode_size"><span style="font-family: Aptos, Aptos_EmbeddedFont, Aptos_MSFontService, Calibri, Helvetica, sans-serif;" class="mycode_font">[<span style="color: #c82613;" class="mycode_color">376.04</span>, <span style="color: #0c882a;" class="mycode_color">-129.14</span>, <span style="color: #0c64c0;" class="mycode_color">50.51</span>, <span style="color: #c82613;" class="mycode_color">92.49</span>, <span style="color: #0c882a;" class="mycode_color">-0.89</span>, <span style="color: #0c64c0;" class="mycode_color">91.95</span>]</span></span></span><br />
<br />
How could it be that the joints are the same, but the end flange positions are so different? I estimated that the discrepancy was because of the difference in DH parameters. When they make the robot, Techman does a factory calibration so their simulation in TMFlow is accurate. So, my goal is to have a model representative of this factory calibration in RoboDK.<br />
<br />
To start I used the command "get kinematic signature" while connecting to the robot, which produced the following:<br />

<br />
When I tried to visualize the Flexiv Rizon 4s Workspace in RoboDK, the workspace points are scattered rather than a usual visualization of sphere. why is that so?<br />
<br />
Please help us to understand.<br />

			<description><![CDATA[Hi,<br />
<br />
I have some questions about the TCP calibration by XYZ plane method. I usually use 4 point method with teaching spikes and the controller's builtin calibration method. In order to improve the calibration I am now using a probe and RoboDK however the I am surprised to see the result is worse.<br />
<br />
Should the same point on the plane be touched or should the different postions be as far apart as possible?<br />
When using an ABB robot with AbsAcc should poses or joints be used to feed the calibration data to RoboDK? <br />
<br />
Thank you in advance.<br />

			<description><![CDATA[Hello everyone,<br />
<br />
I am currently working on a robot-to-robot needle handover project in RoboDK using two JAKA cobots (Zu12 and Zu7). I have attached an OnRobot Eyes camera to the end effector of the Zu12 robot alongside a custom two-finger gripper.<br />
<br />
The goal is to perform a synchronized needle handover through a narrow opening. I have already implemented the basic handover sequence using predefined targets and synchronization logic, but I am now exploring vision-based decision making.<br />
<br />
My idea is that as Robot A approaches the handover position, the camera monitors Robot B and determines when it has successfully grasped the needle. Only then would Robot A release the needle and move away. Later in the cycle, Robot B would return the needle and Robot A would use vision again to determine when the needle is in a suitable position for re-grasping.<br />
<br />
I am also considering a second approach where the camera is mounted above the workcell, providing a top-down view of both robots and the handover area, instead of mounting the camera on the robot itself.<br />
<br />
My questions are:<ul class="mycode_list"><li>Is this type of vision-guided robot-to-robot handover possible using the simulated OnRobot Eyes camera in RoboDK?<br />
</li>
<li>Would an eye-in-hand setup (camera on the robot) or an overhead camera be more suitable for this application?<br />
</li>
<li>Can the simulated camera provide useful depth information for detecting successful grasping and object transfer?<br />
</li>
<li>If I want to use machine learning or object detection, can RoboDK be used to generate training data from the simulated camera, or would I need to train and validate using images from the actual OnRobot Eyes camera?<br />
</li>
</ul>
<br />
I am relatively new to RoboDK and still exploring its vision capabilities, so any guidance, recommendations, or examples would be greatly appreciated.<br />
<br />
Thank you.]]></description>
