Although the mdl_hyper3d does not exist in toolbox, we could connect 3 puma560 into a 18dof redundant robot.
puma = rtb.models.ETS.Puma560()
puma_3x = puma.ets() * puma.ets() * puma.ets() #extract the ets and connect 3 of them
robot = rtb.robot.ERobot(puma_3x) #construct a robot using the 18dof ets
