Agenda § § § § Introduce Team Project Background Problem Statement and Project Goals Stakeholders Use Scenarios Customer Requirements Engineering Requirements Preliminary Project Plan March 12, 2021 Rochester Institute of Technology 2
Team Introduction & Roles March 12, 2021 Team Member Role Will Fickenscher Project Manager Erika Mason Electrical Engineer Jared Warren Mechanical Engineer Joe Taddeo Mechanical Engineer Chris Jasinski Mechanical Engineer Rochester Institute of Technology 3
Project Background § Boeing approached RIT to strengthen their relationship § Boeing is interested in funding research to: § § Develop innovative technologies Improve current Unmanned Underwater Vehicle (UUV) systems § Boeing’s interest in RIT: § Mc. Kibben Muscle Robotic Manipulators currently being researched and developed P 08024: Air Muscle Artificial Limb #2 March 12, 2021 Rochester Institute of Technology 4
Problem Statement § Current State § § Boeing does not offer a robotic manipulator on its UUV (Unmanned Underwater Vehicle) Competitors offer manipulators which use hydraulically actuated pincher-style arms § Environmental risks § Low dexterity Echo Ranger March 12, 2021 Rochester Institute of Technology 5
Current Product- Kraft Telerobotics-Raptor § § § § Part electric/part hydraulic Joystick controlled with feedback Gripper Can operate at depths more than 7 miles under the ocean surface Has 6 degrees of freedom Potential to leak hydraulic fluid into environment Lifts 500 lb. Max Kraft Raptor Arm March 12, 2021 Deep sea exploration sub with a Kraft Telerobotics arm Rochester Institute of Technology 6
Problem Statement § Desired State § Highly dexterous anthropomorphic robotic manipulator that operates at depth § Project Goals § § Produce a functional underwater Mc. Kibben Muscle Manipulator prototype Utilize surrounding water as the actuation medium (eco-friendly) § Constraints § § Adhere to Boeing engineering standards and ITAR regulations Use Mc. Kibben Muscle technology Festo Airic’s Arm Shadow Robotics March 12, 2021 Rochester Institute of Technology 7
What is a Mc. Kibben Muscle § Flexible hosing that expands under pressure Mc. Kibben Muscle § Advantages over Hydraulics: § § § Lightweight Greater power-to-weight ratio Low cost Compliant Smooth action March 12, 2021 Rochester Institute of Technology 8
Additional Project Goals § Appropriate design, development, and lessons-learned documentation to be passed on to future MSD teams § Suitable mechanical interface to attach manipulator to UUVs or Exosuits § An intuitive user-control interface Kraft User-Control March 12, 2021 Xbox Controller Rochester Institute of Technology Nuytco Research Ltd. Exosuit 9
Stakeholders March 12, 2021 Rochester Institute of Technology 10
Use Scenarios Considered § Underwater Research § Locating and uncovering artifacts § Better use of tools § Tools will not have to be reengineered to be used for a gripper/clamp manipulator § Fixing mechanical issues § Having a “hand” readily available will make repairing underwater oil rigging systems much simpler and safer March 12, 2021 Rochester Institute of Technology 11
