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 - I have had numerous complaints about the AR3 robots being sold on Ali Express  -  These are not being sold by Annin Robotics. They are illegal counterfeits that violate the projects copyright and terms of use.  These robots come only partially assembled and do not have a wiring harness.  The gear drive motors they use are not factory motors and I get a number of complaints on motor noise and high backlash issues.  The encoders being used are not compatible with the Teensy encoder library and the controller is open loop.  These clones are being delivered with illegal copies of the older AR2 software.  Please do not sent me frustrated emails if you have purchased one of these - they are not being sold by Annin Robotics.  Action is currently underway to have these removed from Alibaba Group sites.  The AR3 free design project is intended to be a DIY platform at the lowest possible cost - not to resell or take advantage of people.
