EvoArm is a 3+2DOF 3D-printed robotic arm, a new design based in part on the LiteArm i2 design by armatec:

Rather than hobby servos, EvoArm is built to accommodate Dynamixel AX-series smart servos, which feature fairly precise position & speed control and feedback without totally breaking the bank. Most of the bearings used are cheap 608-size skateboard bearings.
The design as provided features a flat end-effector, which is designed to provide tactile/haptic feedback, and which adds an additional 2DOF at the wrist to the base arm's 3DOF.
