Introduction
The rapid growth of e-commerce has transformed consumer shopping habits while presenting unprecedented challenges to the logistics industry. The "last hundred meters" of delivery—the final leg from distribution centers to customers' doorsteps—has become a critical bottleneck, plagued by inefficiency and high costs. Traditional delivery methods rely heavily on manual labor, which is time-consuming, labor-intensive, and vulnerable to traffic congestion, parking difficulties, and other urban obstacles. To address these challenges, the logistics sector is actively exploring innovative solutions, including drones, autonomous vehicles, and delivery robots. Ford's collaboration with Agility Robotics to develop the Digit robot represents a bold attempt to tackle the "last hundred meters" problem, signaling a transformative shift in future logistics. This report analyzes the challenges and opportunities of last-mile delivery, evaluates Digit's technological features and applications, and explores the potential of autonomous vehicle-bipedal robot collaboration to reshape logistics.
Chapter 1: The "Last Hundred Meters" – The Bottleneck of Modern Logistics
1.1 Definition and Importance
The "last hundred meters" (or "last-mile") delivery refers to the final stage of transporting goods from distribution centers or transit hubs to end customers. Though this segment constitutes a small portion of the supply chain, its impact is disproportionately significant. Efficient last-mile delivery directly influences customer satisfaction and loyalty, enhancing trust in e-commerce platforms and driving sales growth. Conversely, poor delivery experiences can lead to customer attrition.
1.2 Challenges
Key challenges include:
- High labor costs: Manual delivery is expensive, particularly in urban areas with traffic congestion and parking shortages.
- Complex environments: Urban landscapes with multi-story buildings, gated communities, and restricted vehicle access complicate deliveries.
- Unpredictable demand: Varying customer preferences for delivery times and locations require flexible solutions.
- Surge in parcel volume: E-commerce growth has exponentially increased package quantities, straining traditional systems.
- Safety risks: Delivery personnel face hazards like accidents, theft, and fraudulent activities.
1.3 Cost Analysis
The last hundred meters account for up to 53% of total logistics costs, including labor, vehicle maintenance, operational overheads, and package loss.
1.4 Significance of Solutions
Overcoming these challenges would improve efficiency, reduce costs, enhance customer experiences, and drive technological innovation in logistics.

- Foldable design: Compact storage in autonomous vehicles.
2.2 Applications
Digit is suited for:
- E-commerce deliveries
- Food and grocery shipments
- Medical supply transport
2.3 Pros and Cons
Advantages:
Efficiency gains, cost reduction, adaptability to complex environments.
Limitations:
Technological immaturity, safety concerns, regulatory hurdles, and high upfront costs.

3.1 Role of Autonomous Vehicles
Self-driving vehicles excel at long-haul bulk transport, while Digit handles localized "last hundred meters" delivery.
3.2 Synergistic Benefits
- Faster deliveries through division of labor
- Lower operational costs
- Enhanced safety via advanced sensors
3.3 Operational Models
Collaboration modes include fixed depots, mobile hubs, and hybrid systems tailored to population density.
3.4 Challenges
Technical integration, safety protocols, regulatory frameworks, and ethical considerations remain unresolved.
Chapter 4: The Competitive Landscape
Major players like Amazon (drones), DHL (autonomous trucks), and startups (e.g., Starship Technologies) are developing competing solutions. The sector is characterized by technological diversification and regional adaptation.
Chapter 5: Opportunities and Challenges for Digit
5.1 Opportunities
Growing e-commerce demand, technological advancements, and policy support favor adoption.
5.2 Challenges
Public acceptance, infrastructure requirements (charging stations), and ethical debates about job displacement pose hurdles.
Chapter 6: Conclusions and Recommendations
Digit represents an innovative approach to last-mile logistics but requires:
- Increased R&D investment
