Gas Bots (ECE4007L03)

Based on the application it was determined that data rate and range were the most important factors

in the decision making process. Since the project involves streaming live images from the camera mounted

on the device to the remote user, a high data rate is essential. Also the range should be sufficiently large so

that the user can be at a safe distance from the area of surveillance. From Table 7, it was determined that

Wi-Fi offers the best data rate and range in comparison to all the other technologies under consideration.

The network topology is not of a concern as each device will have its own command center, so the point to

hub topology of the Wi-Fi works in favor of the project. From Table 7, it can also be seen that the Wi-Fi

has the highest power consumption as compared to the other technologies. It has the highest energy

consumption among all the three competing technologies. This limitation will be overcome by using an

onboard portable battery to power the Network Interface Card (NIC) and the eBox.

5. Schedule, Tasks, and Milestones

The Gas Bot will be designed and built over the next two months. There are many important tasks

which are critical to the timely completion of the project. Of all the tasks, the following three tasks are

considered as the most important milestones:

The onboard camera should be able to send live streaming video to the remote computer.

This would allow the remote user to see which way the robot is moving. There are multiple

components that have to be integrated in order to achieve this milestone.

The onboard sensor should be able to send live data to the remote computer reliably. To

achieve this milestone, the sensor’s analog signal must be converted to digital signal using a

microcontroller.

The remote user should be able to send instructions to the robot regarding directions.

For the complete schedule, please refer to Appendix A.
