Project Scope
Description
- Remote Controlled Mobile Robot for Surveillance
- Would like an Operational Prototype bumping into things by April, 2012
- 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, Nov 21, 2011
- Phase 1 - Design and Project Planning (Dec 2011)
- Phase 2 - Mobile Base (Jan 2011)
- Phase 3 - Power System (Feb 2012)
- Phase 4 - Computer System (Mar 2012)
- Phase 5 - Video System (Apr 2012)
- Phase 6 - Operational Prototype (May 2012)
- Phase 7 - Deploy the Prototype (Jun 2012 until recycled)
- Phase 8 - Repeat and Improve the Project (Jul 2012 to Dec 2012)
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
- Compact ATR 4WD RC Kit
- 4WD ATR RC Kit with 32mm motors, video
- Heavy Duty 4WD All Terrain Robot Kit, video
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
