There are 5 groups of parts needed to build the AR2 or the AR3 robot:

 

  • Covers and Spacers - these are 3D printed parts you print yourself (see the Bill of Materials at the beginning of the robot assembly manual)

 

  • Structural Components - these are the 27 main structural parts, you can 3D print them yourself or you can purchase aluminum components listed below (also see Bill of Materials at the beginning of the robot assembly manual).

 

  • Hardware Components - these includes all the bearings, belts, pulleys, sprockets, chain, shafts, pins, screws etc. these parts are available in a kit listed below or you can source yourself (see Bill of Materials at the beginning of the robot assembly manual).

 

  • Stepper Motors and Drivers - these are available in a package directly from Stepper Online (see link on this page - also see Bill of Materials at the beginning of the robot assembly manual).

 

  • Electrical components - these are all the misc electrical components needed for the robot, enclosure and wiring harness.  These components are all available from Amazon or Ali Express and are listed in the Bill of Materials section at the beginning of the robot assembly manual.

Please also review all tutorial videos listed on the Tutorials page.  The setup/calibration videos as well as the programming videos are very helpful in understanding how the robot works.

Warning on eBay and AliExpress sellers.  I have received a number of emails from frustrated individuals who have purchased an AR3 from eBay and AliExpress thinking they were purchasing a fully assembled AR3 with controller only to receive an AR2 & AR3 Aluminum and Hardware Kits Combo.  I sell hundreds of combo kits to various buyers all over the world and in China but I have no way of knowing which buyers are reselling them on AliExpress or eBay. The fine print on most of these ads say that they do not come with a wiring harness or that they don’t come with controls but the ads appear to be selling a complete AR3 robot. I have tried contacting AliExpress and eBay about misleading ads and the AR3 being sold in violation of the project copyright license but no response is ever given. Beware of these sellers.
