A Starship Technologies delivery robot impeded wheelchair users at the University of Pittsburgh, resulting in the suspension of the service,

Doctoral student Emily Ackerman reported being trapped on Forbes Avenue when a robot blocked the only accessible entrance to the sidewalk, posing a safety hazard as traffic approached. 

The incident, along with similar complaints from other wheelchair users, led the university to temporarily suspend the use of the robots. 

Starship Technologies acknowledged the issue and stated that the incident was due to a mapping error, which has since been addressed. 

The company also emphasised its commitment to accessibility and is working with local advocacy groups to improve the robots' interactions with mobility devices. 

The situation highlighted the challenges autonomous delivery robots face in ensuring accessibility and safety for all pedestrians, particularly those with mobility impairments.
