We live in an era where a few taps on a smartphone can bring anything sold at a grocery store straight to your front door. As the hassle of visiting a store in person, browsing the aisles, and hauling heavy bags home has faded away, consumers have naturally gravitated toward online shopping. In response to this shift, major retailers are gradually scaling back their brick-and-mortar locations and doubling down on online logistics. As more consumers demand faster and safer delivery, the importance of final mile delivery — the final leg of the journey that ultimately determines overall delivery quality — has never been greater.

The Last 1km That Defines Delivery Quality: Final Mile
Key Summary The “final mile” is the stretch between a regional distribution center and your front door — the only point where a business directly meets its customer, and a segment that accounts for a significant share of total logistics costs, much of it concentrated in household-by-household labor.
The stretch between a regional distribution center and your front door is known as the “final mile.” It is the only point in the entire logistics process where a business directly meets its customer, and it is the critical stage that shapes the first impression of any delivery service.
Final mile delivery is widely cited as accounting for a significant share of total logistics costs, often described as more than half. A large portion of that expense is concentrated in the labor required to visit each individual household, making it a segment that companies must optimize if they hope to improve their bottom line.
Since the COVID-19 pandemic, the explosion of contactless services and surging parcel volumes have pushed labor-intensive delivery systems to their limits. In response, efforts to improve logistics efficiency through autonomous delivery robots have been more active than ever.
How Autonomous Technology Is Transforming Logistics
Key Summary Automated guided vehicles (AGVs), autonomous mobile robots (AMRs), and self-driving forklifts already work around the clock in logistics sites. Based on capabilities proven indoors, robots are now expanding their scope to last-mile delivery right to our doorsteps.
In fact, the introduction of such delivery robot technology has already begun in logistics sites around us. Automated guided vehicles (AGVs) that follow fixed routes, autonomous mobile robots (AMRs) that perceive their surroundings and find paths on their own, and self-driving forklifts are already working around the clock.
The introduction of these machines has visibly transformed logistics operations. Thanks to their accurate navigation capabilities, robots can move safely even through narrow corridors, improving warehouse space efficiency. In particular, systems that bring items directly to workers have dramatically reduced unnecessary movement and increased overall throughput.
Robots that operate continuously 24 hours a day have become a key driver of faster order processing and reduced fulfillment errors. By taking over high-risk tasks involving heavy cargo, they have also improved workplace safety. Workers, in turn, have shifted from repetitive manual tasks to roles focused on system management and oversight.
Based on technological capabilities proven in indoor logistics environments, robots are now breaking free from the limited confines of warehouses and preparing for new changes by expanding their scope to the realm of last-mile delivery right to our doorsteps.
Outdoor Environments: New Challenges for Delivery Robots
Key Summary Unlike controlled indoor spaces, outdoor environments present constantly changing conditions — uneven pavement, gravel paths, curbs, and steep inclines that demand far more torque. For last-mile robots to drive stably, the performance of the drive unit is important.
The journey from a logistics facility to your front door is far from simple. Unlike the controlled indoors, outdoor environments present constantly changing conditions: uneven pavement joints, irregular gravel paths, and unexpected curbs that must be navigated at every turn.
When approaching underground parking ramp entrances or steep inclines like apartment access slopes, a robot must output several times more torque than it would on flat ground. Add to that the unpredictable reality of weaving between pedestrians, electric scooters, and parked vehicles, and the challenge becomes clear.
Ultimately, for last-mile delivery robots to overcome these challenges and drive stably, the performance of the drive unit that enables driving in any environment is important.
The BSR Drive Technology Behind Stable Operation
Key Summary Bonsystems’ BSR (Bonsystems Speed Reducer) applies a proprietary cycloidal tooth profile design. Transmitting power through a rolling motion mechanism reduces load concentration at any single contact point, while high torque output within a compact form factor lets the robot climb challenging terrain and frees interior space for added battery capacity.
Bonsystems’ BSR (Bonsystems Speed Reducer) is a key solution that enhances the completeness of these outdoor delivery robots. Delivery robots that run continuously for 24 hours must be backed by robust durability capable of withstanding repeated load shifts and external impacts. To meet this demand, the BSR applies a proprietary cycloidal tooth profile design that delivers a stable drive environment.
The cycloidal tooth profile transmits power through a rolling motion mechanism. This reduces load concentration at any single contact point, minimizing gear wear, and helps maintain consistent performance even under repeated impact conditions caused by pavement joints or irregular surfaces, lowering the risk of damage in the process.
Beyond durability, the BSR speed reducer achieves high torque output within a compact form factor. This means that even when carrying heavy cargo, the robot can reliably climb a range of challenging terrain, from underground parking ramps to steep inclines.
The compact structure also offers a practical advantage in the confined interior space of an outdoor delivery robot. Reducing the volume taken up by the drive module frees up room inside the robot. If that space is used to add extra battery capacity, it can extend operating range and improve overall efficiency per shift.
In this way, the BSR combines durability, high torque, and a compact design to keep outdoor delivery robots running reliably across a wide range of conditions. Final mile delivery robots in particular must repeatedly navigate sidewalks, ramps, and building entrances, environments that are difficult to predict, making the reliability of the drive system a defining factor in overall service quality.
As robot-friendly infrastructure such as dedicated robot elevators, threshold-free entrances, and gentle ramps expands in the future, many robots will operate in various environments, and stable driving technology will be widely required. Through our compact yet powerful BSR speed reducer technology, we remain committed to advancing drive solutions that allow robots to move through our everyday lives more safely and more efficiently. If you have questions about our BSR speed reducer technology or are working through component selection decisions in the development of a final mile delivery robot, please feel free to reach out through the Bonsystems website.
FAQ
Q: Why does last mile delivery account for the largest share of total logistics costs?
A: It comes down to the structure of the process itself. Large-scale freight between major distribution hubs moves massive quantities of goods in a single trip, but the final leg requires visiting individual households one by one. The labor and travel costs that accumulate across those individual stops are what push this single segment to over half of total logistics expenditure.
Q: Can robots used inside a warehouse simply be redeployed for outdoor delivery?
A: Indoor warehouses are flat, controlled environments where robots only need to follow predefined routes. Outdoors, the variables are endless: pavement joints, gravel paths, inclines, pedestrians, electric scooters, and more. Technology validated in a warehouse can serve as a foundation, but outdoor delivery demands a significantly higher level of durability and driving stability on top of that.
Q: How is our surrounding environment changing as delivery robots become more common?
A: The changes are already underway. Buildings designed with robots in mind are beginning to appear, featuring dedicated robot elevators and step-free entryways that allow robots to move freely. The spread of delivery robots is influencing more than just how packages are delivered; it is beginning to shape how buildings are designed and how urban infrastructure is planned.
Q: Why is the drive component especially critical in a final mile delivery robot?
A: Outdoor delivery robots operate all day without rest, carrying heavy payloads across irregular surfaces. Every stretch of that route channels repeated shocks and loads directly through the drive components. Even if a robot has excellent hardware and software, if the drive system cannot hold up, the service simply cannot run. The real-world operational reliability of a delivery robot ultimately rests on the durability of its drive technology.
Q: What does reducing the size of the drive unit have to do with delivery efficiency?
A: Space inside a robot is limited, so the smaller the drive module, the more room there is to install additional battery capacity. Greater battery capacity means more households can be served on a single charge, reducing the number of times a robot must return for recharging and increasing the total number of deliveries it can complete in a day. For this reason, a compact drive structure is a key factor in improving final mile delivery efficiency.
