Bender is a 5 DoF arm built by a community member, @rkitect, on his own. It is a thoughtful arm the keeps the price low by 3D printing timing belt pulleys rather than expensive gears. Rohit took it one step further by making it a ROS Node! His 3D CAD files are available here. He also has a nice homepage with videos and pictures at this link. On the homepage there are also links to Rohit’s Github page. Rohit has one caveat on this robot – that is that the shoulder joint doesn’t yet have enough torque to fully lift the arm. Those looking to build an arm should pitch in and help Rohit with this issue.
