Conclusions

For in-person offerings of CSC 161,

• Control of robots has served as an worthwhile application area (not practical for virtual courses)
• MyroC provides a function library to handle behind-the-scenes support for C programs to Scribbler 2 robots
• Basics of Bluetooth communication follow a standard protocol
  • based on an Media Access Control (MAC) address
  • each operating system can be tailored in its own way to improve user usability
• Processing of many commands follows a common approach
  • a 9-byte command is sent to the robot
  • the robot echos the 9-byte command back to the workstation
  • the robot performs the command
  • the robot may return 11-bytes of sensor data
  • the robot may return additional requested data
• An eSpeak speech synthesizer can aid robot processing and testing
  • eSpeak runs as a separate process
  • a pipe provides communication between a MyroC program and eSpeak
  • implementation details vary among operating systems.
