Robotic surface treating system

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 an end effector is defined at a distal end of the lower arm section. The upper arm section includes a pair of generally parallel arm members which are connected between the shoulder joint and the elbow joint and which are configured to define a yoke at the elbow joint at which the lower arm section is connected. 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 and has flexibility in how the robotic arm is driven and how suction is routed through the machine.
