Dorna 2 Review: Specs, Price and Applications of the Five-Axis Tabletop Robot Arm
Updated: 7 days ago
The Dorna 2 is a five-axis tabletop robot arm with a payload of 1.5 kg, a reach of 500 mm and 0.2 mm repeatability, listed from USD 3,590. This review covers its specifications, design, programming options, applications and price.
Quick Verdict
The Dorna 2 is a small industrial-style arm from Dorna Robotics of California. It carries 1.5 kg over 500 mm at up to 1000 mm/s, uses closed-loop control and can drive up to three auxiliary axes such as rails or rotary tables. It is controlled through web-based software that runs on different devices. It suits light, fast handling in laboratories and small production cells. With five axes it cannot orient its tool as freely as a six-axis arm, and for that Dorna offers the six-axis Dorna TA.

Design and Build Quality
The Dorna 2 is built as a tabletop arm for industrial tasks. Its closed-loop control checks the position of each joint, which protects accuracy when the arm is loaded, and the controller can run up to three further closed-loop axes, so that a rail, a lift or a rotary table can be added without a second control system. The maker describes the arm as industrial grade and low in maintenance. Buyers who need more payload and accuracy in the same size can choose the Dorna 2S.
Programming and Software
Web-Based Control
The arm is controlled and programmed through web-based software that runs on several platforms, so it can be operated from a computer or tablet without installing a dedicated application.
Motion Engine
The motion engine generates trajectories for the arm together with its auxiliary axes.
Dorna 2 Applications and Use Cases
Typical applications for the Dorna 2 are pick and place, assembly, dispensing, inspection and laboratory automation.
Pick and Place and Packaging
The speed of 1000 mm/s suits fast transfer of light parts and small-scale packaging.
Dispensing and Assembly
The arm is used for gluing, sealing and filling, and for assembly of small components.
