ARX LIFT3
ARX's new mobile two-arm robot: two arms on a lifting column, an omnidirectional base and an RTX 5070 on board.
Key facts
ARX LIFT3 is ARX's new mobile two-arm robot. A column raises and lowers both arms through about 380 mm, an omnidirectional-wheel base moves it in any direction, and an RTX 5070 on board handles control and perception. Each arm has six joints plus a gripper, about 1 kg peak payload and an arm span of about 780 mm. The robot weighs about 39 kg.

Questions about LIFT3
How far does the column lift the arms?
About 380 mm. The column carries the shoulder and both arms together, so you can work at low tables and at counters with the same robot.
What arms does LIFT3 have?
Two arms with six joints plus a gripper each, about 1 kg peak payload and about 780 mm from base to gripper tip. In ARX's LIFT3 CAD model both arms share the kinematics of the X5 arm.
What computer and software does it use?
An RTX 5070 on board runs control and perception. ARX lists Python on Ubuntu 24.04 (x86) for development. Tell us the software you plan to use and we will confirm what ships with the robot.
How big is it?
With the column lowered and the arms folded, LIFT3 measures about 610 × 675 × 760 mm. It weighs about 39 kg.
