Project Scope

Description

  • Remote Controlled Mobile Robot for Surveillance
  • Would like an Operational Prototype bumping into things by Oct 2014
  • Educational On-going Project for Industrial Applications
  • Design and Implementation to be Repeatable and as much Open Source as practical

Basic Requirements

  • PTZ (Pan-Tilt-Zoom) Camera, e.g. Axis 213. Vertical telescoping would be nice
  • 4WD able to navigate over 1" high obstacles and 20 deg incline with full payload
  • Docking mechanism for recharging
  • 802.11 wifi
  • Laptop or SBC (Single Board Computer) for remote control using RDP or VNC
  • Minimize cost of first operational prototype (so we aren't afraid to make mistakes)
  • Use existing and open source resources as much as possible (so we can recover quickly from our mistakes)
  • Machine Shop Conditions, enclosed electronics


Project Schedule

Initial Estimate, Jan 25, 2014

  • Phase 1 - Design and Project Planning (Feb 2014)
  • Phase 2 - Mobile Base (Mar 2014)
  • Phase 3 - Power System (Apr 2014)
  • Phase 4 - Computer System (May 2014)
  • Phase 5 - Video System (Jun 2014)
  • Phase 6 - Operational Prototype (Sep 2014)
  • Phase 7 - Deploy the Prototype (Oct 2014 until recycled)
  • Phase 8 - Improve the Project (Nov 2014 to Dec 2014)

Phase 1 - Design and Project Planning

  • Estimate Energy Requirements
  • Estimate Payload Requirements
  • Identify I/O Requirements
  • Review Available Ready Made, Kit Platforms, Controllers/Computers, Cameras.

Requirements Details for First Prototype

  • 1.) How far does it need to go per charge? Battery Life long enough to be usable and allow return to charger
  • 2.) How fast does it need to go? H-Mart Produce Section Shopping Cart Speed (slow with lots of stops)
  • 3.) What are the size constraints (e.g. if it needs to go down aisles which are 16" wide, that's noteworthy)? Footprint = Laptop + Camera + Tires
  • 4.) Are we guaranteed to have wifi coverage everywhere the robot will be roaming around? Yes
  • 5.) What resolution camera will you need and will the shop/warehouse lighting be adequate? Prototype will use an existing Axis 213PTZ, has IR for night vision. Additional lighting not required.

Phase 2 - Mobile Base

  • Design Overall Concepts for Desired Operational Prototype
  • Construct or Purchase the Mobile Base
  • Test, Review and Revise Design Concepts Based on current work in progress

Candidate Kit Platforms

==== SuperDroidRobots Bare Bones Kits

RC Kits

Phase 3 - Power System

  • Construct or Purchase Batteries, Charger, Hardware, etc.
  • Interface Power System to Mobile Base
  • Test, Review and Revise Design Concepts Based on current work in progress

Energy Requirements

  • 1.) Axis 213PTZ Camera = 12VDC, 2A
  • 2.) Motion Controller(s) and Motors = 12VDC, 3A x 4
  • 3.) A laptop will have its own battery, but require 20VDC, 10A (or less) for recharge.
  • 4.) An SBC(Single Board Computer) will require 12VDC, 2A or less
  • 5.) Maximum battery capacity is desired. If stock chassis, then get max that fits within payload limits. Batteries should be modular to change quantity/capacity for payload weight and balance adjustments.

Phase 4 - Computer System

  • Construct or Purchase Computer Control System
  • Interface Computer Control System to Power System and Mobile Base
  • Test, Review and Revise Design Concepts Based on current work in progress
  • We should now have a functional remote controlled Robot!

Phase 5 - Video System

  • Add PTZ Camera
  • Interface Camera to Robot
  • Test, Review and Revise Design Concepts Based on current work in progress
  • We should now have a functional remote controlled Surveillance Robot!

Phase 6 - Operational Prototype

  • Play and Fine Tune the Surveillance Robot Performance

Phase 7 - Deploy the Prototype

  • Gain Operational Experience

Phase 8 - Repeat and Improve the Project

  • Include Additional Features and Functionality
