Dobot CR10A

CR10A is the arm Dobot positions in the middle of the collaborative range: 10 kg of payload reaching 1,300 mm, repeatability of +/-0.03 mm and 350 W of draw. Its place in the family is easiest to read against the CR16AL, which is physically the same size - identical 1,300 mm radius, identical 40 kg of arm, identical 350 W - but lifts 16 kg instead of 10. The manufacturer charges for that extra payload in motion: the CR16AL runs its first three joints at 110 deg/s against 150 and 180 deg/s here, and its repeatability drops to +/-0.04 mm. Read the other way, the CR10A is the faster and more precise half of a pair of arms that share a skeleton. 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 claims a 25% shorter cycle time than the previous CR series. One inconsistency in Dobot's own published data is 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. Dobot publishes no list price and no separate datasheet for this model; every figure here comes from the series comparison table.
