Forthcoming poster presentation comparing early robotic surgical skill acquisition
and learning-curve progression between the Hugo RAS and Da Vinci X platforms amongst novice trainees.
About this presentation
This work compares early skill acquisition and learning-curve progression amongst novice trainees using the Hugo RAS and Da Vinci X robotic platforms. The study contributes to understanding whether platform-related differences affect early technical development and the design of cross-platform robotic surgical training. Callum Pearse will present the poster at ERUS26 in Padua.

Poster presenting a multimodal dataset designed to support objective robotic surgical skill evaluation
and performance analytics across two robotic surgical platforms.
About this presentation
This poster presented the acquisition and structure of a multimodal dataset capturing kinematic and complementary data streams across two robotic surgical platforms. The work supports objective skill evaluation, simulation-based training research, and future machine-learning approaches to robotic surgical performance assessment.

Background
The increasing use of surgical robotic systems has driven higher training demand, highlighting the need for objective metrics to standardise training, improve learning curves, and optimise patient outcomes. As a pilot exploration, bimanual dexterity may offer a robust, task-independent, objective metric that distinguishes expertise.
Objectives
To analyse the correlation between left- and right-hand workspace volumes in novice and intermediate robotic surgeons to determine whether this relationship reflects bimanual dexterity and can be utilised as an objective performance measure of expertise.
Methods
This pilot study collected data from 21 participants, with 4 excluded due to incomplete datasets. Depth cameras captured kinematic data from 11 novices and 6 intermediates. Spearman’s correlation assessed workspace volume relationships, with 95% confidence intervals derived via bootstrapping.
Results
Novices demonstrated a moderate negative correlation (Spearman’s ρ=-0.4636, p=0.1509, 95% CI: -0.9720-0.3116) whereas intermediates showed a weak positive correlation (ρ=0.2571, p=0.6228, 95% CI: -1.0000-1.0000). Despite no statistical significance, intermediates exhibited more synchronised workspace utilisation, potentially indicating greater bimanual dexterity.
Patient Benefit
Objective metrics of expertise could enhance training, improve patient outcomes by ensuring proficiency before independent practice, and enable standardisation of robotic surgical training.
Conclusion
As a pilot study with a small sample size, this provides preliminary insight into a possible correlation between left- and right-hand workspaces in novices and intermediates. Ongoing data collection and analysis may prove a statistically significant relationship, allowing the integration of this metric into a machine learning model to provide feedback to trainees and enable predictions of the effectiveness of surgical skill acquisition.
