Structural Improvement For Robotic Cleaner

An improved structure for robotic cleaner, that comprises at least:

• a chassis with plurality of spherical casters fixed to the periphery of bottom deck that can be free to roll when exerted an external force,
• a dust collector mounted on the chassis that can move together with the chassis to collect the miscellaneous articles and dusts along the path of movement,
• a lifting actuation mechanism mounted on the chassis that includes a lifting power supply at least to output power through a linking device as a minimum,
• a first swing arm set that comprises of two parallel & extending first swing arms as a minimum with one end of the first swing arm jointed respectively to the linking device of the lifting actuation mechanism and driven to rotate pivotally to perform the action of support & outward stretch or inward retraction and with the other end of the first swing mounted a drive wheel each,
• a second swing arm set that comprises of two parallel & extending first swing arms as a minimum with one end of the first swing arm jointed respectively to the linking device of the lifting actuation mechanism and driven to rotate pivotally in a direction opposite to the first swing arm to perform the action of support & outward stretch or inward retraction, and with the other end of the second swing arms mounted a driven each,
• plural advancing power supplies mounted at the middle section of the first swing arms each that can drive each drive wheel to rotate in forward and backward.
