Case Study
Imagine a factory floor where assemblies seamlessly move between workstations, orchestrated entirely by a digital task list and the manufacturing schedule. This was the vision: a fully automated and dynamic system for transporting assemblies, eliminating manual handling and optimising workflow.
Our client, a seasoned integrator with a strong background in Automated Guided Vehicles (AGVs) and mobile machinery, encountered a challenge that stretched beyond their existing expertise. While proficient in line-following AGVs with differential drive systems, this project demanded a leap into more sophisticated robotics.
The requirements presented a unique set of hurdles:
This robot needed to navigate freely within the factory, guided by a central fleet management system, not physical lines.
Due to the significant length of the assembly being transported, full holonomic capabilities were essential for precise manoeuvring in tight spaces.
The robot was not intended to operate in isolation. It needed to seamlessly integrate with a fleet of similar robots, intelligently coordinating movements to prevent bottlenecks and ensure smooth flow.
The robot required intricate interlocks and PLC integration to facilitate seamless communication with the assembly stations.
The closed-source and proprietary nature of the existing software integrations added a layer of complexity to the development process.
To overcome these challenges, a bespoke robotics solution was engineered from the ground up:
Kinematic Modelling and Motion Control: Given the unique robot design and closed-source nature of its core systems, the first crucial step involved developing a comprehensive kinematic model of the robot. This mathematical representation of the robot's movement was then used to create a sophisticated motion control system implemented in C++. Rigorous testing was conducted, initially in a virtual simulation environment and subsequently on a physical sub-assembly comprising a single drive/steer unit. This iterative approach ensured the accuracy and reliability of the core movement algorithms.
Fleet Management System Integration: To enable seamless integration with the central control system, a custom plugin for the fleet management system was developed. This plugin meticulously defined the robot's precise motion model and physical dimensions, effectively outlining its permissible range of movements while proactively preventing potential collisions with other robots or static obstacles.
Intelligent Traffic Management: To optimise the flow of assemblies and prevent congestion, a custom traffic rule set was designed and implemented. This intelligent system efficiently processed mission requests (assembly movement instructions) originating from the plant's PLC. By strategically planning robot tasks, the system ensured optimal utilisation of the robot fleet and minimised potential delays.
Extended Task Data Integration: The task data managed by the system was further enhanced to incorporate control signals for the robot's lifting mechanisms and communication protocols for interacting with the assembly stations. This comprehensive approach ensured a fully integrated and automated assembly transfer process.
