To address the limitations related to weight and walking speed consistency, several design improvements can be implemented. Firstly, the use of lightweight materials in the construction of the backpack frame and enclosure can help reduce overall weight without compromising durability. Additionally, incorporating adjustable straps and ergonomic padding can enhance comfort for the operator, making it easier to carry the backpack over long distances.
To ensure consistent walking speed during data collection, integrating a feedback control system that provides real-time feedback to the operator on their walking pace can be beneficial. This feedback can be visual or auditory cues that help the operator maintain a steady speed. Furthermore, implementing a suspension system within the backpack frame to minimize vibrations caused by walking movements can improve the stability of the sensors and reduce oscillations in the data collected.
