Dobot CR16A

CR16A lifts 16 kg - forty percent of its own 40 kg - which in this family is bettered only by the CR30A. The trade is reach: 1,000 mm, the shortest radius among the four 350 W arms and 300 mm less than the CR16AL, which carries the same 16 kg and weighs the same. What the CR16A keeps in exchange is speed and precision, running the same 150/180/223 deg/s joints as the CR10A and CR12A at +/-0.03 mm, where the longer CR16AL slows to 110 deg/s in the first three joints and loosens to +/-0.04 mm. Maximum linear speed is 4 m/s, a step down from the 5 m/s of the shorter-payload arms. 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.
