 +==== Polyscope (the teaching pendant) ====
  
-Applications+=== Define TCP === 
 +  * Click ‘new’ (you cant rename TCP’s) 
 +  * Define the position 
 +    * Enter the offset by measuring, or use the wizard. The wizard lets you orient the physical TCP around a point in 4 different positions. 
 +  * Define the orientation (optional) 
 +    * Enter a custom orientation in case the TCP is not normal to the flange. 
 +  * Define a tool weight and center of gravity. 
 +  * Click ‘set as default’ 
 +  * Save the installation setting (on the left bar)
  
-===== Software ===== +Test the setup: 
- +  * rotate the robot around the TCP on the teaching pendant (move tab)The tool tip should stay still in space while the rest of the robot rotates around it.

 == Installation == == Installation ==
  
-Install 'Robotsplugin (on Mac) for Grasshopper on Rhino 7: +  * In Rhino, go to ''Tools > Package Manager'' and select the ''online'' tab. 
-  * Download the last release of the plugin: [[https://github.com/visose/Robots/releases]]+  * Search for 'Robots' and select the 'Robots' plugin. If you select it, check the Github url: the author is visose
-    * In Grasshopper, go to 'File > Special Folders > Components Folder'This opens a finder window+  * Select version ''1.4.1'' and click install (restart Rhino after)
-    * Put the downloaded files ('Robots.dll', and 'Robots.gha') in this folder. +    * Everything below version ''1.5.0'' probably works
-    * Instructions were given to Windows users to give write permission to the filesNot sure if it applies to MacOS too. +    * Briefly tested versions: ''1.0.1'', ''1.3.0'', ''1.4.1'' seem to work''1.5.0'', ''1.6.0'' are too new for the get-current-position-script (see below). 
-  * Download the zip file from this Github repository: [[https://github.com/visose/Robots]]: on the top rightclick 'code > download .zip'Alt+click to download individual files doesn't work as it results in HTML files instead of the raw xml files+ 
-    Unzip the file. A folder 'Robots-masteris created+== Robots.dll file == 
-    * Make a folder called 'Robots' in your user directory ('/Users/username/Robots'). + 
-    * Move the contents from 'Robots-master > Librariesto the newly created 'Robots' folder in the user directory.+If Rhino keeps asking to locate the Robots.dll filehere's a tipMake all grasshopper projects (files with a ''.gh'' extension) writable. This way you'll need to reference the location of the ''robot.dll'' file only once.  
 +  On mac: cmd + i, under sharing & permissions, change the privilege of 'everyoneto Read & Write. 
 +  * Location of the robots.dll file: 
 +    * ''username/Library/Application Support/McNeel/Rhinoceros/packages/7.0/Robots/1.4.1/Robots.dll''

 I tried adapting the 'simple example' by changing the Kuka robot to a UR10 robot. It works, but the initial position is all wrong.

 +== Setup ==
 +  * Do not connect to the LAN network of KASK. Instead connect to the robot arm directly, or via a separate switch.
 +  * Set the computer to a static IP address that is the same as the Robot's, except for the last number
