If this product were continue to be developed, the next steps will be the following:

Our client is interesting in using it, but will it be a product also for the SWAT team?

Also there is still some concern about privacy using it indoors but not outdoors.

 

Parts that  might be redesigned in the future:

1)Redesign the main board  making standalone. By making it standalone it will cuts costs and reduce time wiring and configuring third party boards like Xbee and Arduino.

2)Adding an heavy duty camera stand. The current camera stand is unstable and causes some problems to the l293d because its quality and because

both use PWM at the same time.

3) Forget about third-party boards like the Arduino and Xbee. All these boards make the designer to depend so much on them. I would rather build my own data RF transmitter/receiver and use

a real microcontroller like Atmel AVR than use those boards anymore. Those boards were used in this project because my team member were not familiar with the Atmel AVR technolgy and RF signals.

I did not want to push them further.

4) Changing from plexiglass to aluminum remote controller enclosure because aluminum will make the remote controller heavy duty.

 

Possible New Functionalities:

 1)Add key switch in the remote control, so it adds extra protection against accidentally deploying the containers.

2)Add a two way video system so the user can communicate with the people near the robot.

3)Change the chassis from a 4 wheeled to 6 wheeled to make the robot climb taller obstacles.

4) Nigh vision camera

5) Flash light on the robot

 

All the current functionalities are needed and extra functionaly won’t hurt the project. A priority functionality will be adding a nigh vision camera so the robot can

operates in dark places.

 

The only possible solution to the problem of deploying a tear gas grenade without risking a officer’s life is to create robot with the mentioned characteristics as in this project.
