Future Improvements
1. Sensor Choice
- The sensor was the cause of most of our problems. Accelerometers are subject to noise problems. The noise made our position calculations very difficult. We may be able to offset some of the noise by using a filter.
- Our goal was to design a low cost product, so we tried to design the KazERASER with a low cost sensor. Another solution may be to buy a more accurate sensor or encoder. However, the sensors we considered were substantially more expensive than the accelerometer we used.
2. Implementing R/C batteries
The KazERASER drained 9 volt batteries rather quickly. Using larger capacity R/C batteries should allow for longer run times and better performance.
3. Programming We may continue to tune our program to improve the path of the KazERASER. We could also implement PID control, as we only used P control.
