Optimizing Robotic Precision: Unleash Real-Time Performance With Advanced Foundational Software Solutions

POSTED 02/09/2024

The field of robotics is a dynamic and swiftly evolving industry, with an emphasis on the development of advanced robotic systems and components. This evolving landscape underscores the increasing demand for systems that are not only cutting-edge but also marked by accuracy, precision, and reliability. At the heart of these systems are robotic devices (e.g., SCARA, Cartesian, Delta, Articulated Arm, Automated Guided Vehicles, Autonomous Mobile Robots), essential for automating operations. As we delve deeper, we encounter the perennial challenge of achieving the desired levels of precision and accuracy in the world of industrial automation and robotic devices.

One of the most formidable adversaries in this type of software development is “jitter” response. This term alludes to the deviation in timing, manifesting as rapid, small, and often unpredictable variations or fluctuations in a robot’s movements, positions, or behaviors. Jitter is highly undesirable as it can result in imprecise actions, leading to erroneous outcomes, and in the worst-case scenarios, it may induce instability in robotic systems, compelling them to revert to predefined safe states. The importance of minimizing jitter cannot be overstated, especially in applications where precision and accuracy are paramount.

Yet, jitter represents just the tip of the iceberg of performance challenges. The second protagonist in this narrative is “latency.” Latency refers to delay or time lag between an input or action and the corresponding response or output within a robotic system. It is an inevitable aspect of any robotic system since instantaneous response with zero latency is a technological impossibility. The crux of the matter is to determine how much latency is acceptable in any given context. The higher or more unbounded the latency, the greater its potential to disrupt the reliability, accuracy, and precision of robotic systems.

Let us explore the profound impact of latency on specific industries. Take industrial robotics as an example, where latency affects processes that require high precision and synchronization, such as manufacturing and assembly lines, or material handling. In these settings, even a modest degree of latency between the issuance of a command and its execution by the robot can result in misalignment, inaccuracies, and lack of precision in the production process. The consequences can range from the production of defective items to diminished throughput and increased operational downtime.

In the realm of medical robotics, particularly in applications like robot-assisted surgery, latency is not merely a concern – it is a critical factor. In these scenarios, surgeons operate devices remotely, and any delay between their movements and the robotic device’s response can have dire consequences. Increased or unbound latency can lead to imprecise movements and reduced control, ultimately jeopardizing patient safety. Thus, the imperative is to minimize latency, ensuring real-time precision and accurate manipulation in medical robotic systems.

In environments where real-time and deterministic response is a non-negotiable requirement, the underlying operating system that manages the entire software ecosystem that is running the robotic system must be meticulously designed to minimize both jitter and latency. A sluggish or inefficient software framework can lead to delayed actions and jittery movements, which are not conducive to optimal robotic performance. Achieving efficiency in the operational core of the system is paramount, as any shortcomings here can cascade into compromised robot performance and ultimately suboptimal outcomes.

In the following sections, we will embark on a comprehensive journey through the intricate terrain of performance challenges in robotics across a spectrum of industries. We will explore the foundational software strategies, innovations, and best practices employed by developers to minimize jitter and latency, reinforcing our commitment to address the performance challenges that underpin the robotics revolution across various sectors.
