Robotic navigation has been a prominent area of development within many industries over a significant period of time. Due to such high complexity, the employment of human within tele-operation systems remain to be the most effective method to address these applications. It is a widely accepted notion that the enablement of human intuition within these systems is primarily linked to the user’s situational awareness, yet upon investigation it was identified that the conventional design methodology employed was quite inadequate. Through further investigation it was identified that this methodology focuses only on one of the three elements widely accepted to determine situational awareness, which is the primary reason for its inadequacy to assist designers to develop systems for limited network environments. In order to investigate an improved design methodology for these particular environments experimentation was conducted into exploring the relationship between users’ situational awareness and the amount of data provided to further analyse the determination of the 'Right' data for the system - an element disregarded within the conventional methodology.

Experimentation was conducted by assessing the awareness of the user with varying degrees of data, considering image and LiDAR hardware. This research identified that a logarithmic relationship existed between these parameters for both the image and LiDAR hardware considered. With the additional support of a qualitative analysis, these findings indicated that a particularly significant reduction in the data requirements of a system may be attained with negligible reduction in situational awareness. Through these analyses various other conclusions could be drawn for this relationship considering other influential factors which may assist to create a more effective system within a limited network environment.

In consideration of the situational awareness definition initially consulted, these findings were applied to suggest a more effective design methodology. This methodology encourages the designer to first determine the 'right' data for the system considering design objectives and network limitations before applying an iterative approach. As such, the optimal compromise between the situational awareness and data transfer requirements may be considered to better address the design objective of the tele-robotic system in a limited network environment.
