Patent number 11865711 is assigned to Cognibiotics AB (Lund, Sweden).The following quote was obtained by the news editors from the background information supplied bythe inventors: “High safety installations are needed for example at direct collaboration between humanand robot and when it is an advantage to use fenceless robot installations. Looking at the state of art,there are parallel kinematic robots (as the Delta robot described in WO1987003528A1), which have all theactuators mounted on a fixed stand and where it is therefore possible to obtain a light weight structure.However, these parallel kinematic robots have the disadvantage that the arm system occupies a very largespace and that the workspace is very small in relation to the space needed for the arm system. Therefore,these robots can only be used for applications where a large space is available for the arm system andwhere it is enough to have a very restricted workspace, especially in the vertical direction. Thus, the Deltarobot is mainly used for pick- and place operations above a flat surface such as a conveyor belt with plentyof space for the robot arm structure.
