Dallas Makerspace, Dallas Personal Robotics Group, and a mysterious third party are collaborating on a super secret robot design project. Print this page, memorize it, and then burn it.

Project Goals

The GreeterBot project will build two robots:

  1. A stationary humanoid robot with, emotive head, articulated arm, and static lower body located in the reception area of an office suite. This robot is called GreeterBot, and it greets visitors. GreeterBot has a camera it its head.
  2. A mobile robot which starts in the vicinity of GreeterBot and leads the visitor to their destination. This robot is called Livid Lobster, or "the lobster" for short.

When someone enters the office suite, GreeterBot will welcome them and ask who they've come to see. It will offer them the option of replying by speaking to the robot, or by touching a person's name on a touch screen. When the visitor has selected a tenant, it will indicate with an arm motion which of two hallways they should walk down, and will announce orally which office they should go to. It will then point to the lobster and instruct them to follow it.

The lobster will then move from the base of GreeterBot down the appropriate aisle as far as the destination office.

Meetings are planned to be held every other Tuesday alternating with Saturday. Stay tuned to find out exactly what this means.

Next group meeting September 13 at Cali's office 7pm 4002 Beltline Rd #110 Addison. (Surveyor & Beltline between Marsh & Miday)

Project Policies

  • The Project Manager has the final say on everything
  • Subteam leads make technology decisions for their area. Others outside the team may offer suggestions and opinions on how a subsystem design should be., but the subteam lead makes the decision. Subteam leads are expected to actively engage other subsystem team leads, to get the interface definitions between the subsystems clear.
  • If you need to buy materials, send Cali & Paul a note asking for authorization. For items purchased from the web, include a link - Cali may try to get it donated. When you receive permission to purchase, buy it & expense it back to Cali (give her the receipt).
