The ground mobile robotics study is structured on the two pivotal members namely Sensor perception and Motion planning. Sensor perception or Exteroception comprises the ability of measurement of the layout of environment relative to vehicle’s frame of reference which is a necessity for the implementation of safe navigation towards the goal destination in an unstructured environment. Environment scanning has played a significant role in mobile robots application to investigate the unexplored environment in the sector of defence while transporting and handling material in warehouse and hospitals. Motion Planning is a conjunction of analysing the sensor’s information about the local frame and global map while being able to plan the route from starting point to the target destination. In this paper, a 3600 2-D LiDAR is used to capture the spatial information of the surrounding, the scanning results are presented in a local and global map. The LiDAR’s output is further transformed into an Occupancy grid for the comprehension of the Motion Planning module to process the path. Probabilistic Roadmap and Vector Field Histogram are two…
 

New Technologies for Airframe Structural Assemblies

To be published on 2019-09-16 by SAE International in United States
With air traffic demand constantly increasing and several years of aircraft production in their backlog, major aircraft manufacturers are now shifting their focus toward improving assembly process efficiency. One of the most promising solutions, known as “One Side Assembly”, aims to perform the whole assembly sequence from one side of the structure (drilling, temporary fastener installation and removal, blind fastener installation, assembly control) and with a high level of integrated automation. Investments in robotic equipment, automation engineering and innovation are very active and automation capabilities have already increased a lot in the aerospace industry. As an example, drilling operations for large dimensions airframe are clearly moving from manual to automated. However, despite more and more clever and sophisticated robotics, the use of historical fasteners with two side installation method remains a strong limitation to innovative automated assembly sequences. A blind fastener which can provide the same mechanical characteristics than current structural fasteners, while providing automation friendly features and meeting cost objectives is a real “must have” for assembly process efficiency improvements. It is also full…
 

Intelligent Real Time Inspection of Rivet Quality Supported by Human-Robot-Collaboration

Aircraft production is facing various technical challenges, such as large product dimensions, complex joining processes and the organization of assembly tasks. Meeting the requirements that come with large dimensions, low tolerances and small batch sizes, in combination with complex joining processes, automation and labour-intensive inspection task, is often difficult to achieve in an economically viable way. ZeMA believes that a semi-automated approach is the most effective for optimizing aircraft section assembly. An effective optimization of aircraft production can be achieved with a semi-automated riveting process for solid rivets using Human-Robot-Collaboration in combination with an intuitive Human-Machine-Interaction operating concept. While using dynamic task sharing between human and robot based on their skills, and considering ergonomics, the determined ideal solution involves placing a robot inside the section barrel. The robot’s workspace is expanded by mounting it on top of a lifting unit so that it can properly position the anvil. In the meantime, the human performs the more complex tasks of inserting the solid rivets and operating the riveting hammer from the outside of the section barrel.…
 

Orbital Drilling Optimization in High Speed Machining and Fatigue Life Enhancement by Orbital Roller Burnishing : Application to an Aluminum Alloy

Orbital drilling has proved to be advantageous to achieve aeronautical-level quality drilling (surface roughness, geometry control…) fully adapted for complex assemblies in a single operation. However, compared to conventional drilling method, this process leads to a drastic change in structure's fatigue life probably due to a non-optimised level of residual stress. The control of the mechanical behaviour of parts obtained by orbital drilling is the goal of the European-CleanSky collaborative R&D project RODEO (Robotized Orbital Drilling Equipment and Optimized Residual Stresses, GA no.738219). In this work, an orbital drilling unit (ORBIBOT) allowing high-speed-machining conditions was developed by PRECISE France, that can be integrated on a lightweight industrial robot. Cutting parameters were determined through an original Tool-Material Couple optimization strategy dedicated to orbital drilling, developed with MITIS Engineering and carried out on aluminium alloy 2024-T351. In order to enhance the mechanical behaviour of the system (fatigue, surface hardening…), an innovative mechanical surface treatment has been introduced for investigations: orbital roller burnishing, performed right after orbital drilling. The burnisher follows a helical path around the hole axis.…
 

Local Weakening of Honeycomb Core for Improved Surface Quality and Bonding in Co-cured Sandwich Panels

To be published on 2019-09-16 by SAE International in United States
Sandwich panels made of NOMEX honeycomb core and fiber reinforced face sheets are a major component of aircraft interior parts. A common way to locally increase the strength of such panels, e.g. for load introduction, is the local thickening of the face sheets with additional prepreg layers. Curing of such strengthened panels without further processing of the core leads to higher flatness tolerances due to the added thickness as well as residual stresses. Machining of the core in the strengthened areas is possible, but expensive due to high machine costs and additional cleaning processes. In this paper a new automated process for the reduction of the residual stresses in strengthened areas is presented. The process is based on a local reduction of the compressive strength in the surface area of the honeycomb core, which allows for a plastic deformation in thickened areas at curing pressure. For the reduction of compressive strength, a concept based on a robot guided tool with multiple parallel blades is presented. A model based analysis of the process parameters shows that…
 

Robotics Motion Control: The Complex Relationship Between Movement and Task

  • Magazine Article
  • TBMG-34808
Published 2019-07-01 by Tech Briefs Media Group in United States

As more medical companies seek robots for increasingly complex tasks such as robotic-assisted surgeries, systems developers tasked with building these robots see an even greater demand for sophisticated robotic control and tasking software. Robot motion control enables articulated arms to move through the action of rotating and sliding joints, and mobile robots to move through locomotion and steering. This controlled motion enables these complex tasks with whatever end effector is appropriate on the robot. Task can be manipulative, as when using a gripper, or sensory, as when positioning and capturing data with a camera.

Face-Tracking Robot

A robot is being developed that tracks facial movements to perform human tasks. The robot resembles large, squiggly arms holding tiny cameras. Sitting in a rolling office chair across from one of the arms, the robot's developer, Nathan Huber, demonstrates how it works. Huber rolls from left to write, forward and back, and the robot's camera follows his movements. He programmed the robot to track objects in planes. First, it identifies the object and locates it on the X and Y axes. Then, with a spatial-tracking algorithm, the robot can determine how near or far an object is in order to grab it.
