Acceleration Robotics announces ROBOTCORE ROS 2 and RTPS Boosting ROS 2 Communications from 62x to Thousands-Fold Faster

ROBOTCORE ROS 2 latency breakdown

ROBOTCORE® ROS 2 significantly enhances the networking architecture of robotic systems and tackles one the widely critizied issues of ROS 2: its latency overhead over the DDS communication middleware.

ROBOTCORE ROS 2 and RTPS Pave the Way Towards Robot-specific Chips Setting New Benchmarks in Performance, Energy-efficiency and Reliability for ROS 2 Networking

VITORIA, ÁLAVA, SPAIN, November 21, 2023 /EINPresswire.com/ -- Acceleration Robotics — a robotics semiconductor startup founded in the Basque Country, Spain and with offices in India— announced results after one year of development with the release of ROBOTCORE® ROS 2 and ROBOTCORE® RTPS. This marks a significant milestone in the field of robotics networking by implementing in hardware (prototyped with an FPGA) technology that allows robots to exchange information in less than 2.5 microseconds. ROBOTCORE® ROS 2 and ROBOTCORE® RTPSare designed to revolutionize robotics and ROS 2 networking communications, delivering speeds from 62x to thousands of times faster than current standards.

5 years pursuing better robot hardware
==================================
ROBOTCORE® ROS 2 is the result of the last 5 years working towards faster and more efficient hardware for robots. In 2018, Mayoral-Vilches and his team released a series of papers that investigated robot networking and unveiled that modern CPU-based networking solutions, even when optimized, could not cope with many of the real-time needs of modern distributed robotic systems in industry. Custom computer architectures meant for robotics were in need. For the last years Mayoral-Vilches has been working with top experts from industry and academia – including Intel, AMD, Microchip or Harvard among others– to create tools to develop such systems and performance benchmarking. First with ROBOTCORE and later with RobotPerf, this work has attracted hundreds across industry and academia due to its relevance for the future of robotics computing.

ROBOTCORE® ROS 2 is the latest result from this series and delivers absolute determinism via hardware when combined with underlying ROBOTCORE® RTPS and ROBOTCORE® UDP/IP designs. Compared to software-based solutions, it ensures that the communication latency is lower, consuming less energy and that latency remains always the same, regardless of the load of the system. Crucial for real-time robotic systems and solving major bottlenecks in robotic communications today.

ROBOTCORE® ROS 2: A New Era of High-Speed Robotics Networking
=============================================================
ROBOTCORE® ROS 2 is an expertly crafted hardware design that implements the ROS 2 robotics framework. Similarly, ROBOTCORE RTPS implements in hardware the Real-Time Publish Subscribe (RTPS) protocol and parts of the Data Distribution Service (DDS) communication middleware, a relevant communication backbone of robotics. Leveraging the power of FPGA technology for quick prototyping and implementation, this robot core (also known as IP core), is engineered to dramatically enhance the speed of ROS 2 robot networking communications. This means faster data processing, reduced latency, and improved synchronization across robotics systems. Powering the future of accelerated robotics networking, ROBOTCORE® ROS 2 can send or receive packages in less than 2.5 microseconds, accelerating networking by more than 62x on average when compared to traditional software implementations on modern CPUs.

ROS 2 is instrumental in robotics and among its capabilities, it delivers a message-passing infrastructure for robots that acts like a communication 'databus', a system that connects and transfers data between robotic components over the network (unlike a database that stores data). ROBOTCORE® ROS 2 delivers faster robot data transmission or reception over multiple data link layers (both wired and wireless), leading to reduced latency and more determinism, crucial for real-time applications in robotics. ROBOTCORE® ROS 2 can send or receive small ROS 2 messages in less than 2.5 us (one-way) and establish a round-trip communication within 5 us for control applications, accelerating networking by more than 62x when compared to traditional software implementations on modern CPUs. When considering the worst case scenario (maximum latency) for small ROS 2 messages, ROBOTCORE ROS 2 remains deterministic, reporting a consistent round-trip latency below 5 us. Opposed to this, software implementations on modern CPUs take on average 339 us for the same task, but can reach latencies of 22.7 ms (22700 us) or more, which means ROBOTCORE ROS 2 is Thousands-Fold (4540x) faster in these worst case scenarios.
