Robotics Center's spec table leaves voltage, communication interface, encoder and reducer type blank, so they are not recorded here (Group F recorded CAN / 48 V / planetary from Pakronics and AIFITLAB listings — not re-fetched in this pass). Mass conflict on the page: \"Weight 880 g\" vs \"Net weight 1.5 kg\" (the latter is probably shipping weight); 880 g recorded. Dimensions 106 x 106 x 56 mm.
