FINAL WORDS
FIRE has a lot of flaws which needs to be fixed.
1. There are no sensors at the back. This has been a big disadvantage considering the size of the robot. It has a tough time getting out of room corners.
2. There is no protection for the boards from pointed obstacles.
3. The L298 motor driver is pretty inefficient. I should have used the LMD18298.
4. 5 out of 6 boards were etched a home. This required a lot of effort. I had to make the IR board out of a general purpose board because of the complexity of the circuit. Somehow I could not leave it to softwares to design my own board. EAGLE is a good layout editor though.
5. I should have searched around for better motors with the shaft coming out from the axis of the motor.
6. The robot needs more functionality. Just 2 sensors is no good. I am thinking of incorporating sonars. Also I intend to replace the camera with a low resolution vision system. Add to this computer control using FM and DTMF and my robot will be perfect.....(sometime in the future)
