  • Technical Paper
  • 2019-01-2611
To be published on 2019-10-22 by SAE International in United States
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 the 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 analyzing the sensor's information 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 map 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 methods used for Motion Planning.…

Smartphone App Programs Robots

  • Magazine Article
  • TBMG-35292
Published 2019-10-01 by Tech Briefs Media Group in United States

A smartphone app was developed that allows a user to easily program any robot to perform a mundane activity such as picking up parts from one area and delivering them to another. The app, called VRa, uses augmented reality and allows the user to either walk out where the robot should go to perform its tasks or draw out a workflow directly into real space. The app offers options for how those tasks can be performed such as under a certain time limit, on repeat, or after a machine has done its job.

Published 2019-10-01 by Tech Briefs Media Group in United States

Soft robots have a distinct advantage over rigid robots: they can adapt to complex environments, handle fragile objects, and interact safely with humans. Made from silicone, rubber, or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.

Tiny “Walking” Motor Moves in Discrete Mechanical Steps

  • Magazine Article
  • TBMG-35261
Published 2019-10-01 by Tech Briefs Media Group in United States

A set of five tiny fundamental parts can be assembled into a wide variety of functional devices including a tiny “walking” motor that can move back and forth across a surface or turn the gears of a machine. The work offers an alternative to current approaches to constructing robots, which largely fall into one of two types: custom machines that work well but are relatively expensive and inflexible, and reconfigurable ones that sacrifice performance for versatility.

New Technologies for Airframe Structural Assemblies

LISI Aerospace-Mehdi Dahane
Published 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

PIKON Deutschland AG-Benjamin Duppe, Albert Schulz
ZeMA GmbH-Rainer Mueller, Matthias Vette, Tobias Masiak
Published 2019-09-16 by SAE International in United States
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 labor-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.By implementing a…

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

INSA Toulouse-Alain Daidie
Université Paul Sabatier Ups-Landry Arnaud Kamgaing Souop, Yann Landon, Johanna Senatore
Published 2019-09-16 by SAE International in United States
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 2024-T351 Aluminum alloy. 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…
