Projects 1: Project Kickoff Meeting

Project: Design an Interface between a Robot and a

LTU Laptop

Group members:

Colin Black

Steve Holcomb

objective
Objective
  • Design and implement an interface between a robot and a LTU laptop
target goals
Target Goals:
  • Robot should be able to traverse forwards and backwards with the capability to turn
  • Robot should be able to travel at two to three speeds
  • Interface should be easily available for use in third-party programs
    • i.e. writing maze-traversal programs

Interface

power sub system
Power Sub-System
  • Capable of powering interface and robot
    • Laptop runs on batteries
  • Power sources under consideration:
    • Batteries
      • Heavy
      • Limited functional time
    • 110V connection to maze exterior
      • Limits size of maze
      • Requires addition of transformer on robot
drive sub system
Drive Sub-System
  • A single drive wheel located at the rear of the robot
  • Variable speed bi-directional motor
  • Controlled through interface board
  • Tachometer connected to drive wheel for distance/speed reporting to interface
steering sub system
Steering Sub-System
  • Based on standard Rack and Pinion design
  • Single servo/motor to control steering angle
  • Angle controlled through interface board
sensor systems
Sensor systems
  • Initial sensor type: touch
  • Sensor contact causes immediate event/interrupt; drive halted
  • Expansion of system possible to include other sensor types
laptop interface
Laptop Interface
  • Use of Handyboard to relay commands to drive/steering sub-systems and contact data from sensor sub-system
  • Laptop interfaces to Handyboard through Parallel/Serial port
  • Interface to third-party programs through binary API or compile-time headers
    • Knowledge of Windows 2k/XP Device Drivers required
