looks like some hefty machining went into the arm joint, no doubt donated by the thunder chickens? it looks similar to the hinge on their 2008 robot.
as for the drivetrain, the pnumatics dropping down the middle "strafe wheel" as you pull up your traction wheels gives this robot some fierce adaptability. don't expect to be able to pin 148 anyway similar to lone star 2009.
yet again, the robowranglers seem to make use of almost every motor in the kit, while still maintaining an elegant design. good work.
