Area Of Science

  • Robotics
  • Mechanical Engineering
  • Civil Engineering

Background

  • High-rise buildings with curved facades present mobility and anchoring challenges for cleaning robots.
  • Existing facade-cleaning systems struggle with complex architectural designs, limiting operational efficiency and safety.

Purpose Of The Study

  • To develop and evaluate a novel rope-riding mobile anchor (RMA) system for facade-cleaning robots.
  • To enhance the mobility, anchoring, and operational range of robots on convex building surfaces.

Main Methods

  • The RMA system utilizes caterpillar tracks with U-shaped grooves for horizontal movement along a roof-mounted nylon rope.
  • A four-bar linkage mechanism is employed to increase rope contact friction, ensuring secure fixation.
  • The system's structural principle was chosen for simplicity, load stability, and efficient actuation.

Main Results

  • The RMA system successfully supported a payload of 50.5 kg without slippage under tensions up to 495.24 N.
  • The system demonstrated a reduction in the facade-cleaning robot's power consumption during operation.
  • Experimental validation confirmed the RMA's capability to reposition anchors on convex surfaces.

Conclusions

  • The developed rope-riding mobile anchor system effectively addresses the challenges of cleaning robots on curved building facades.
  • The RMA enhances safety, stability, and extends the working range of facade-cleaning robots on complex structures.
  • This innovation offers a practical solution for improving robotic facade maintenance in modern architecture.

Pumped Concrete 01:13

Concrete in large quantities can be pumped across long distances for placing in inaccessible sites. This system comprises a hopper that receives concrete from a mixer, a pump to propel the concrete, and pipelines that facilitate its delivery.
For direct-acting pumps, the concrete enters the pump via the inlet valve under the action of gravity and suction created by the movement of the piston. This concrete is then forced into the pipeline and out through the outlet valve by the forward movement...

Masonry Loadbearing Walls 01:16

159

Masonry load-bearing walls, constructed from materials like brick, stone, or concrete masonry units, serve as a crucial component in building structures by supporting the loads from floors and roofs and transferring them to the foundation. These walls, known for their compressive strength, can be reinforced or unreinforced to suit different building needs, accommodating both the dead and live loads while maintaining safety through lower working stresses compared to the materials' ultimate...

Masonry Curtain Walls 01:20

1.2K

Masonry curtain walls employ brick or stone veneers supported by the building's structure to form an external cladding system that is both aesthetically appealing and functional. These walls are erected through two principal techniques, first by traditional layering of masonry units and second by using prefabricated panels. Traditional construction relies on steel shelf angles attached to the spandrel beam for support, with high-bond mortars ensuring secure attachment of masonry veneer...

Anchoring Junctions 01:03

Anchoring junctions are multiprotein complexes that help cells connect to other cells and the extracellular matrix. Anchoring junctions are present on the lateral and basal surfaces of cells, providing strong and flexible connections. Focal adhesions are often formed due to cell interactions with the ECM substrata, which initiate signal transduction via kinase cascades and other mechanisms. Together, they provide stability and tissue integrity. There are three types of anchoring junctions:...

Posttensioned Masonry Walls 01:15

Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...

Prestressed Concrete 01:20

Prestressed concrete is a construction technique designed to enhance the strength and durability of concrete structures. This method involves the application of a pre-set tension to high-strength steel strands used as reinforcement before the concrete is subjected to its working loads. The primary aim of prestressing is to place the concrete in a state of compression, in order to counteract the tensile forces it will experience in service. This pre-compression helps prevent crack formation in...
