Dobot CR6AL
Dobot · China · 2026
The longest arm Dobot sells and, on the manufacturer's own table, one of its most precise: 1,800 mm of reach with +/-0.02 mm repeatability, carrying 6 kg. Added to the range in March 2026.
CR6AL is the long-reach member of the CRA family and it breaks the rule that precision falls away with length. It covers a 1,800 mm radius - 100 mm more than the 20 kg flagship and nearly three times the smallest arm - yet Dobot rates it at +/-0.02 mm repeatability, the tightest figure in the range, while the 800 mm CR7A is rated at +/-0.05 mm. It also has the widest elbow travel in the family at +/-170 deg. The price is payload: 6 kg, less than the 7 kg CR7A, on 41.5 kg of arm drawing 350 W. Dobot published no launch announcement; the model entered the specification table between January and July 2026 and its product image was uploaded on 20 March 2026, which is where this catalogue takes the year from. Common to the CRA series: six rotary axes, a stand-alone safety controller rated PLd Cat.3 with more than twenty safety functions, certification to ISO 13849-1, ISO 10218-1 and ISO/TS 15066, laser calibration giving absolute positioning accuracy under 0.4 mm, an electromagnetic brake that engages within 18 ms and holds position within 1 mm on power loss, 24 digital inputs and outputs with both PNP and NPN switching, and Modbus TCP/RTU, EtherNet/IP and PROFINET as standard. The arm runs DobotStudio Pro; a 10.1-inch teach pendant, the SafeSkin proximity layer (15 cm pre-collision sensing, 0.01 s monitoring, 0.1 s response) and the VX500 five-megapixel smart camera are optional. Dobot rates the joints of this generation at up to 223 deg/s and claims a 25% shorter cycle time than the previous CR series. Two inconsistencies in Dobot's own published data are worth recording rather than hiding. The series comparison table gives this family maximum linear speeds of 3 to 5.5 m/s, while the CR20A product page puts maximum TCP speed at 2,000 mm/s - a gap of nearly threefold that the manufacturer does not explain. And in the same comparison table the ingress-protection row for the two largest models displays a repeatability figure instead of an IP rating; the CR20A product page states IP54 for both arm and control box, which is what this catalogue publishes.
