When Delivery Robots Collide with People#
They roll down sidewalks at walking pace, carrying burritos and prescriptions. They fly overhead with packages destined for your doorstep. Delivery robots promised a future where goods arrive autonomously—but that future includes pedestrians struck on sidewalks, cyclists knocked off bikes, and drones crashing into homes.
Unlike most autonomous technology that operates in controlled environments, delivery robots navigate public spaces where vulnerable pedestrians have every right to be. When these machines cause harm, the liability questions span product defects, premises liability, and public safety regulation.
Types of Delivery Robots and Associated Risks#
Sidewalk Delivery Robots (PEDs)#
Small wheeled robots sharing pedestrian infrastructure.
Major Operators:
- Starship Technologies
- Serve Robotics
- Kiwibot
- Coco
- Cartken
Physical Characteristics:
- Weight: 40-100 lbs typically
- Speed: 4-6 mph (walking pace)
- Height: knee-level (2-3 feet)
- Navigation: cameras, sensors, GPS
Injury Scenarios:
| Scenario | Description | Common Injuries |
|---|---|---|
| Pedestrian Strike | Robot collides with walking person | Falls, bruises, fractures |
| Trip Hazard | Person trips over stationary or slow robot | Falls, head injuries, fractures |
| Sidewalk Obstruction | Robot blocks path, forcing pedestrian into danger | Struck by vehicles, falls |
| Cyclist Collision | Robot enters bike path or shared space | Falls, road rash, fractures |
| Mobility Aid Conflict | Robot blocks wheelchairs, walkers, strollers | Entrapment, falls, access denial |
| Child Interaction | Children approach, touch, or chase robots | Pinch injuries, falls, traffic exposure |
The Accessibility Crisis
Drone Delivery (UAVs)#

└─────────────────────────────────────────────────────────────────────────┘
Product Liability#
Claims against robot and drone manufacturers:
Design Defect:
- Sensor arrays inadequate for pedestrian detection
- Speed settings too high for pedestrian environments
- Obstacle avoidance insufficient for vulnerable users
- Battery design creating fire risk
Manufacturing Defect:
- Individual unit sensor failures
- Motor or brake malfunctions
- Structural weaknesses
- Software bugs in specific units
Failure to Warn:
- Inadequate pedestrian awareness of robot presence
- Missing warnings on robot exterior
- Insufficient notice to hearing/visually impaired
- Lack of emergency stop information for bystanders
Premises Liability#
Property owners permitting robot operations:
Universities and Campuses:
- Duty to maintain safe premises
- Foreseeable robot-pedestrian conflicts
- Obligations to disabled students and visitors
Shopping Centers and Malls:
- Invitee protection obligations
- Control over robot access
- Security and monitoring duties
Municipalities:
- Sidewalk safety obligations
- Permitting and regulation
- ADA compliance requirements
Negligent Operation#
Claims against delivery platforms and operators:
- Route planning through high-pedestrian areas
- Operating during dangerous conditions (rain, crowds)
- Inadequate monitoring and intervention
- Failure to respond to near-miss reports
- Excessive deployment density
Regulatory Framework#
Delivery robot operations face fragmented regulation:
| Level | Scope | Key Requirements |
|---|---|---|
| Federal (FAA) | Drones | Part 107, waivers, airspace |
| Federal (NHTSA) | Road vehicles | Motor vehicle safety standards |
| State | Sidewalk robots | PED laws (varies widely) |
| Local | All delivery robots | Permits, operating zones, hours |
State Personal Delivery Device Laws: Most states now have PED (Personal Delivery Device) legislation addressing:
- Maximum weight and speed limits
- Sidewalk operation permission
- Yield requirements
- Insurance mandates
- Operator registration
Case Studies#

Pedestrian Rights and Robot Operations#
The Public Space Question#
Sidewalks are public spaces designed for pedestrians. Key legal questions:
Who Has Priority?
- Pedestrians have traditional right-of-way on sidewalks
- Robots are non-human occupants without inherent rights
- Commercial activity on public property requires permission
- Disabled pedestrians have ADA-protected access rights
Permitting and Permission:
- Most cities now require delivery robot permits
- Permits may limit locations, hours, and density
- Violations of permit conditions may establish negligence per se
- Municipalities may be liable for inadequate permitting
Insurance Requirements:
- Many jurisdictions require liability insurance
- Insurance may be inadequate for serious injuries
- Uninsured operation may create enhanced liability
Future Regulatory Trends#
Expected Developments:
- Stricter pedestrian detection requirements
- Mandatory accessibility accommodations
- Hours of operation restrictions
- Density limits on robot populations
- Enhanced insurance minimums
- Performance standards and testing requirements
