This dataset contains injury measures during collisions between a mobile service robot – Qolo – and pedestrian dummies: male adult Hybrid-III (H3) and child model 3-years-old (Q3). We present multiple collision scenarios for the assessment of pedestrian safety, considering possible impacts at the legs for adult pedestrians, and legs, chest and head for children. The dataset is available here DOI:10.5281/zenodo.5266447, and the data processing repository on GitHub.
