Central to Ati’s design philosophy is the continuous refinement of algorithms that strike an optimal balance between performance and complexity. This iterative process ensures that the solutions developed by Ati are efficient, reliable, and scalable, enabling them to meet the evolving needs of users and clients.
Our process is to model, simulate and prototype. Strong mathematical foundations coupled with extensive testing in the real world lead to robust engineering solutions. The integration of digital-twin simulations and hardware-in-loop testing holds a pivotal position in Ati's development lifecycle. This practice empowers the team to simulate and evaluate prototypes in virtual environments, minimizing the risk of failures and expediting the iteration process. Moreover, the philosophy is firmly rooted in data-driven design principles. The extensive real-life data collected, which includes over 75K+ kms of testing and analysis of 10K trips a day, forms the bedrock for informed decision-making.
Sherpa employs Natural navigation, involving the use of various sensors and algorithms to enable the robot to navigate its environment in a manner similar to how humans would naturally move through space.
Routine decision-making in natural navigation involves processing data from multiple sensors simultaneously. These sensors include Lidar, cameras, IMU (Inertial Measurement Unit), wheel encoders, GPS, and ultrasonic sensors. By fusing data from these sensors, the robot gains a comprehensive understanding of its environment and can make informed navigation decisions.
Sherpa Guide is the software stack that controls a fleet of Sherpas to provide the robotics fleet service and autonomy functions for individual robots. It includes the Fleet Manager which is the oversight software that runs on a local server, and the Sherpa software for mapping, path planning, and obstacle avoidance. It also includes battery monitoring and maintenance telemetry to assure the highest up-time.
The flagship analytics tool Sanjaya, confers the user with granular insights on operations.
The Ati Motors Fleet Manager handles the duties of a traffic cop, director of fleet operations and arbiter for conflict resolution.
Sherpa’s safety lies on the principle of triple redundancy, drawing inspiration from the robustness found in aviation systems. One critical safety feature is the use of electromechanical braking mechanisms, which are powered by both primary and secondary power sources. This redundancy ensures that the brakes remain functional even in the event of power loss in one system, preventing unintended movement or collisions.
By combining data from various sensors such as LiDAR, cameras, and proximity sensors, the AMR gains a comprehensive understanding of its surroundings. The Sherpa is ISO 3691-4:2020 compliant, establishing a robust safety framework that aligns with industry best practices.
