Autonomous Tracking Vehicle(ATV)

• Team RC
• Bobby Labonte
• Dale Earnhardt
• Rusty Wallace
• Jeff Gordon

2
Project Description

• Problem To design a mobile robot that
• locates and follows a designated target
• Self-contained vehicle, controlled by Motorola
  68HC11 microprocessor
• Uses sensors to track target
• Software acts in real-time

3
Technical Specifications

• ATV is self-contained and runs on an internal
  power supply
• Sensors will detect target up to 10 feet away
• ATV maintains a distance of approximately 36-
  48 from target
• Takes measures to avoid collisions

Software Solution

• Flow of sensor inputs to actuator outputs

11
Test Plan

• Power up vehicle and initialize tracking program.
• Move target laterally and verify IR tracks
  beacon.
• Adjust target distance and verify that sonar
  maintains desired gap.
• Combine the above procedures to test proper
  tracking.
