Abstract: A vacuum cleaning system including a robotic unit including a main body, a traction arrangement defining a ground plane, and an articulated arm. The articulated arm includes an upper arm section and a lower arm section, wherein the upper arm section is attached to the main body at a shoulder joint, and wherein the lower arm section is attached to the upper arm section at an elbow joint, and wherein an end effector is defined at a distal end of the lower arm section. The articulated arm is configured such that the end effector is movable angularly about a first axis with respect to the elbow joint and is movable linearly along a second axis with respect to the elbow joint. The vacuum cleaning system equipped with a robotic arm that is able to bend and flex due to the pivotable upper and lower arm portions, but also extend and rotate through the lower arm or ‘forearm’ portion, providing improved dexterity for the machine.
