AR4 (MK5)
Desktop six axis arm with machined aluminum links, geared closed loop steppers and a Teensy controller, built from kits or self-sourced parts.
BCN3D Moveo
Fully 3D printed 5-axis teaching arm with belt-driven joints, NEMA steppers and an Arduino Mega running modified Marlin.
The short answer
BCN3D Moveo costs less to start: about $500 against $1,200 in parts. BCN3D Moveo has the shorter parts list (28 lines against 94). Both are rated advanced. AR4: The AR4 manual gives conflicting motor part numbers (BOM vs DIP switch table). Check the motor list in Mistakes builders make before ordering.
