The integration of additive manufacturing into the robotics sector has become increasingly common, transforming how robots are designed, produced, and deployed. This synergy is particularly evident in projects aiming to create more agile and cost-effective robotic solutions. For instance, we’ve seen innovative approaches like robots designed to work in swarms to optimize manufacturing processes, exemplified by our Startup of the Year 2019, AMBOTS. Often, the primary driver for incorporating 3D printing technology is to drastically lower the manufacturing cost of robot components, which are traditionally quite expensive. This cost-efficiency has been a central theme in various research endeavors, such as the Flexoskeleton project from UC San Diego, which developed insect-like robots, and the impressive Solo 8 robot dog. Intel’s OpenBot project aligns perfectly with this objective. The American tech giant not only aimed to reduce the financial barrier to entry for robotics but, more importantly, to make the entire platform open-source. This open-source philosophy fosters a collaborative environment, encouraging a global community of developers, engineers, and enthusiasts to contribute improvements, develop new functionalities, and expand the robot’s capabilities. As researchers from Intel explain, their motivation was clear: “Current robots are either expensive or make significant compromises on sensory richness, computational power, and communication capabilities. We propose to leverage smartphones to equip robots with extensive sensor suites and access to a thriving software ecosystem, in a small electric vehicle that costs $50.” This statement encapsulates Intel’s vision for OpenBot – to create a high-capability, low-cost robotics platform by intelligently utilizing existing widespread technology.

The OpenBot Project: Detailed Design and Accessible Construction

The Making of OpenBot: From Digital Files to Tangible Robotics

The design and construction of OpenBot have been carefully orchestrated by Intel Labs to ensure maximum accessibility and ease of replication. For the 3D printing of the robot’s various components, Intel Labs specifically recommends using PLA (Polylactic Acid) material. PLA is widely regarded as one of the simplest thermoplastics to extrude, making it an ideal choice for hobbyists and educational institutions that may not possess advanced technical machinery. Its low melting point and minimal warping make it forgiving to work with on most FDM (Fused Deposition Modeling) 3D printers. The researchers themselves opted for an Ultimaker S5 to fabricate the OpenBot chassis, a premium desktop 3D printer known for its reliability and precision. This choice underscores the importance of quality in the base components, even within an affordable framework. The chassis itself is ingeniously designed, consisting primarily of a bottom plate attached to a protective cover using just six screws. This modular approach simplifies both the printing process and the final assembly.

A key feature of the cover is its integrated universal smartphone holder, equipped with an adjustable spring mechanism. This clever design ensures compatibility with a wide array of smartphone models and sizes, highlighting Intel’s commitment to making OpenBot truly adaptable. Furthermore, the cover includes a strategically placed opening for attaching an Arduino microcontroller, which serves as the robot’s low-level control system and is powered conveniently via a USB connection. The team provided detailed estimates for the 3D printing process, indicating that the bottom plate requires approximately 13.5 hours to print, while the cover, incorporating the phone holder, takes about 9.5 hours. While it is certainly possible to accelerate the printing speed, doing so would inevitably compromise the final precision and overall quality of the components. For those meticulous about their build, adhering to the recommended print settings ensures optimal performance and durability. In terms of weight, the bottom plate weighs in at about 146 grams, and the lid at 103 grams, contributing to the robot’s lightweight and agile nature, crucial for its mobility. Despite the various components, the assembly process is remarkably straightforward. According to the creators of OpenBot, the entire robot can be put together in a brisk 30 to 60 minutes, making it an engaging and rewarding project for individuals of varying technical skill levels.

The Power of the Smartphone: OpenBot’s Intelligent Core

Intel Labs based a significant part of the OpenBot project on the assumption that a vast majority of the global population, estimated at over 40%, now owns a smartphone. This ubiquitous device, often underestimated for its computational power and sensor suite, becomes the ‘brain’ of the OpenBot. The question for Intel was simple yet profound: why not harness the inherent capabilities of these personal devices to propel their robotics project further? This led to the development of a dedicated Android application, which serves as the primary interface for users. This application allows users to collect valuable data from the robot’s environment, control its various functions, and manage its workload with intuitive ease. The Android app seamlessly integrates with an Arduino Nano microcontroller, which handles the essential low-level functions such as precise motor control and sensor input processing. This division of labor is efficient: the smartphone, with its powerful processor, high-resolution cameras, IMUs (Inertial Measurement Units), and extensive connectivity options, manages complex tasks like computer vision, AI model execution, and high-level decision-making. Meanwhile, the Arduino provides reliable, real-time control over the robot’s physical movements, ensuring smooth and responsive operation. This innovative architecture not only dramatically reduces the overall cost of the robot but also grants OpenBot access to a rich software ecosystem and continuous advancements in mobile technology.
