  • Good Evening. This evening Loren Schwappach, Dan Wehnes and myself, Tom Thede, will present the Wanderlink Glove project. This project is primarily focused on providing a human interface device, a glove that will remotely control a robotic arm to function in an environment deemed hazardous to humans.
  • The purpose of the Wanderlink Glove Project is shown: To engineer an innovative, multi-use, portable, light-weight, ergonomic glove-like human interface device. Pressure points will be added along with the capability to detect three-dimensional motion. By using pressure points, the glove will allow the user to remotely control the robotic arm.
  • This list shows a top-level overview of expected functions of the Wanderlink Glove and the different components it will contain.
  • As an overview for the remainder of the presentation, Loren Schwappach will cover the initial design concept, potential contracts/applications, general requirements and expected operations of the Wanderlink Glove to include a black box diagram of the system. I will then cover the system specifications to define the expected values needed to meet system requirements and identify the critical characteristics for our portion of the design effort. Dan Wehnes will finish up the presentation by addressing our acceptance procedures and provide final conclusions. Questions will be addressed as they occur with a final opportunity at the end of the presentation. A list of references is provided at the end to identify the sources for the information provided.
  • Above are some initial concept designs and feature layouts for the Wanderlink Glove.
  • This is a list of general requirements for the Wanderlink Glove.
  • This is a lost of general glove operations, conditions, and expected output for multiple glove operations.
  • This is a rough black box diagram of the Wanderlink Glove.
  • For a complex device like the Wanderlink Glove, there a number of system specifications required. The system specifications for the Wanderlink Glove are shown in the next several slides to include the requirement, a description and expected values for each specification and are not meant to be all inclusive at this point in the design process. The first requirement is a light-weight, portable, power supply that must provide 1.8 Volts to power all glove electronics for a minimum time of three hours. The expected values for the power supply based on market research are a power density of 185 Watt-hours/kilogram and a weight under one half pound. Available lithium-polymer technology batteries will satisfy these requirements. The second requirement is a realistic movement tracking system that monitors motions with six degrees of tracking including the X, Y, Z, Yaw, Pitch, and Roll. To provide this capability, the glove will provide six eight-bit outputs to the CPU every 500 milliseconds. The third requirement is to provide temperature sensing, as a safety feature, to ensure the glove powers down when it exceeds a predetermined temperature to avoid injury to the user. This will be done by the speaker giving a warning signal to the user via the speaker. To monitor the temperature, the glove will provide a six bit output to the CPU every 500 milliseconds. The glove must be synchronized with the robotic arm which will require driver software.
  • Electro-mini-pressure bubbles will apply pressure to the user based on feedback from the robotic arm. This is to ensure that the user does not over apply pressure to the object the robotic arm is holding. The glove will weigh no more than 3 lbs and be available in various sizes to satisfy 95% of working professionals in the market. To sync the glove with the robotic arm, the user will have their hand open palm face down which will be the resting position of the robotic arm. An audio signal will tell the user if calibration was successful in order to begin glove and robotic arm operation.
  • The glove will be used in a room temperature environment.
  • The power supply must be able to drive all the sensors and pressure bubbles properly.
  • The glove controls a robotic arm to work in an environment hazardous to humans.
  • Are there any final questions on the design of the Wanderlink Glove Project?
