The robot performed exceptionally well within the competition, when it was not victim of an un-calibrated colour sensor and a faulty breakout board. It was one of the few robots that could successfully navigate home and did so the most reliably due to the usage of the gyro which neither competitors within the final utilized to travel home. Had the breakout board error not been present causing the robot to crash, and the colour sensor correctly tuned to the arena lighting, all rounds would have more closely emulated that of round four, if not surpassed it. Furthermore, had our unload mechanism been entirely removed from the software, an average of 1.9kgs would have been collected per round, as opposed to the 1.25kg due to six weights …show more content…

To resolve this issue a front unloading mechanism would be implemented. This would mean that the robot would not need to enter far into the base, significantly reducing the chance that a collected weight is pushed from the home base. If this had been implemented then the robot would have had more chances at collecting and returning home without the risk of removing collected weights from the base. This is potentially a competition winning change.
The final design of the robot could only detect weights on the right-hand side. To double the chances of a weight being detected a second weight detection pole should be implemented on the left Perspex guide. This would add a further 100 degrees to the robot’s field of vision. The coding of the weight detection could also have been improved as the robot often became unreliable when the detection pole was close to walls. To solve this the logic implemented to detect weights would need to be made more reliable by including a specific case when both read a value lower than a certain number.
The final feature that should be implemented is to increase the range of the weight detection pole. The final design used a short-range IR sensor to account for the minimum operating distance limitations. However, if a medium IR sensor was also incorporated into this design then the maximum range could be increased to 50 cm whilst still being able to reliably detect weights close to the robot. The ability of
