Performance Study of an Innovative Collaborative Robot Gripper Design on Different Fabric Pick and Place Scenarios

University of Windsor-Morteza Alebooyeh, Bowen Wang, Ruth Jill Urbanic
  • Technical Paper
  • 2020-01-1304
To be published on 2020-04-14 by SAE International in United States
Light-weighting fiber composite materials introduced to reduce vehicle mass and known as innovative materials research activities since they provide high specific stiffness and strength compared to contemporary engineering materials. Nonetheless, there are issues related automation strategies and handling methods. Material handling of flexible textile/fiber components is a process bottleneck and it is currently being performed by setting up multi-stage manual operations for hand layups. Consequently, the long-term research objective is to develop semi-automated pick and place processes for flexible materials utilizing collaborative robots within the process. The immediate research is to experimentally validate innovatively designed grippers for efficient material pick and place tasks. Pick and place experiments on a 0/90 plain woven carbon fiber fabric with an innovative gripper design is tested using a YuMi 14000 ABB collaborative robot to validate the new-designed gripper enhanced performance on the slippage and material wrinkling based on the previous research [20] for two gripping forces, and two travel speeds. Also, different double arm pick and place scenarios are sought to achieve an acceptable approach through which fabric wrinkling…

Case Study on the Challenges and Responses of a Large Turnkey Assembly Line for the C919 Wing

Electroimpact Inc.-Mark Forbes
  • Technical Paper
  • 2020-01-0010
Published 2020-03-10 by SAE International in United States
Design and production of an assembly system for a major aircraft component is a complex undertaking, which demands a large-scale system view. Electroimpact has completed a turnkey assembly line for producing the wing, flap, and aileron structures for the COMAC C919 aircraft in Xi’an, China. The project scope includes assembly process design, material handling design, equipment design, manufacture, installation, and first article production support. Inputs to the assembly line are individual component parts and small subassemblies. The assembly line output is a structurally completed set of wing box, flaps, and ailerons, for delivery to the Final Assembly Line in Shanghai. There is a trend toward defining an assembly line procurement contract by production capacity, versus a list of components, which implies that an equipment supplier must become an owner of production processes. The most significant challenge faced was the amount of front end engineering work required to develop detailed assembly processes and reconcile them with the customer, who remains the actual process owner. Other challenges include aircraft maturity delays, design changes due to process definition…

Performance Levels and Methods of Measurement of Electromagnetic Compatibility of Vehicles, Boats (up to 15 m), and Machines (16.6 Hz to 18 GHz)

Electromagnetic Compatibility (EMC) Standards
  • Ground Vehicle Standard
  • J551/1_202001
  • Current
Published 2020-01-10 by SAE International in United States
This SAE Standard covers the measurement of radio frequency radiated emissions and immunity. Each part details the requirements for a specific type of electromagnetic compatibility (EMC) test and the applicable frequency range of the test method. The methods are applicable to a vehicle, boat, machine or device powered by an internal combustion engine or battery powered electric motor. Operation of all engines or motors (main and auxiliary) of a vehicle, boat, machine or device is included. All equipment normally operating when the vehicle, boat, machine or device is in operation is included. Operator controlled equipment is included or excluded as specified in the individual document parts. As a special case, CISPR 12 applies to battery powered floor finishing equipment, but robot carpet sweepers are excluded. By reference, IEC CISPR 12 and CISPR 25 are adopted as the standards for the measurement of vehicle emissions. In the event that an amendment is made or a new edition is published, the new IEC document shall become part of this standard six months after the publication of the…

Lift Capacity Calculation Method Knuckle-Boom Log Loaders and Certain Forestry Equipment

MTC4, Forestry and Logging Equipment
  • Ground Vehicle Standard
  • J2417_202001
  • Current
Published 2020-01-10 by SAE International in United States
This SAE Standard provides a uniform method to calculate the lift capacity of knuckle-boom log loaders and certain forestry equipment. It establishes definitions and specifies machine conditions for calculations. This document applies to knuckle-boom log loaders as defined in ISO 6814 and ISO 17591 and certain forestry equipment defined in ISO 6814 that have a rotating upper-structure such as feller bunchers, forwarders, harvesters, and behind the cab or rear-mounted knuckle-boom log loaders not having their own power supply. It does not apply to harvesters that are incapable of lifting a tree or log completely off the ground. This document applies to those machines that are crawler, rubber-tired, and pedestal or stationary mounted.

Sensor Perception and Motion Planning for an Autonomous Material Handling Vehicle

Automotive Research Association of India (ARAI)-Sanjay A Patil
Vellore Institute of Technology-Sahil Prabhakar, Dani Priyanka, Ankit Ghosh
Published 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.…

A Study on the Development of an Effective Framework for Implementation and Sustenance of an Obsolescence Material Management System in an Aerospace Supplier Manufacturing Industry Environment

GITAM School of Technology-Mani Rathinam Rajamani, Eshwaraiah Punna
Published 2019-10-11 by SAE International in United States
Obsolescence Material management plays an important and vital role in today’s modern Aerospace manufacturing, Aerospace Maintenance, Repair and Overhaul industry as well as Aerospace Distributors. Aerospace vehicles have a considerable longer product life-cycle when compared to any other consumer goods like automobile and electronics industry. With the advent of new, disruptive technologies, many sources and supplies of materials including COTS and Standard catalogue parts, components and goods, which are widely used in an Aerospace manufacturing environment, are diminishing at a considerable rate and thus result in their obsolescence before the end disposal of the product life cycle. It is one of the leading causes to the sale of counterfeit and fraudulent parts and components, which can result in considerable deterioration of Quality and Cost to Customer. This technical paper emphasizes on the need for implementation of an effective Obsolescence management framework which an Aerospace company can follow through defining, deploying and sustaining Obsolescence Management through Policy, Procedures, Process and People methodology to be followed at manufacturing, maintenance and to identify proactively, notify and mitigate the…
