Re-Vector is a new class of modular robotic arm developed by Ross Innovation for applications where conventional robot geometries impose significant limitations. Its distinctive kinematics enable highly articulated, elbow-free configurations capable of reaching around obstacles, negotiating confined spaces and approaching tasks from a wide range of directions. The modular architecture allows robotic systems to be configured for different working environments, reach requirements and manipulation tasks. Re-Vector's centrally aligned load path and compact articulated profile offer particular advantages in cluttered and difficult-to-access environments. Re-Vector is being developed for applications including aerospace, nuclear decommissioning, advanced manufacturing, inspection and maintenance.

Conventional industrial robotic arms generally employ serial, elbowed geometries, often with six rotational axes, three of which operate in a common plane. Although highly effective in many applications, their geometry can constrain access, require substantial clearance during movement and introduce singularities that complicate motion planning and control. Re-Vector's kinematics are radically different. A repeated sequence of axial, transversal and axial rotational axes along the kinematic chain produces partially decoupled, frusto-spherical joint arrangements. The result is exceptional manipulability. The arm can bend around obstacles, negotiate confined spaces and approach tasks from directions that may be difficult or impossible for conventional robotic arms.

Compact, elbow-free profile: Enables operation in confined and cluttered environments, with reduced risk of snagging and interference.Exceptional manipulability: Transversal joints capable of angular excursions exceeding 90° can be combined along the kinematic chain, allowing the arm to bend around obstacles and negotiate complex access routes.Reduced singularity constraints: Re-Vector's distinctive kinematics avoid many of the singularity-related limitations encountered with conventional elbowed robotic arms, simplifying motion planning across demanding workspaces.Extensive usable workspace: The articulated architecture provides access to positions and approach directions that can be difficult or inaccessible for conventional robotic arms.Modular architecture: Arm configurations can be tailored to application-specific reach, workspace and payload requirements.Centrally aligned load path: The arm's structural arrangement offers advantages in load transmission and mechanical behaviour across different orientations.ROS 2 and MoveIt integration: Supports motion planning, simulation and integration with wider robotic control and autonomy systems.

Re-Vector is an advanced robotic technology with working systems demonstrated in aerospace and nuclear-decommissioning applications. Ross Innovation is now progressing from prototype development towards pre-commercial and application-specific configurations. Further engineering, validation and productisation activities are being undertaken to prepare Re-Vector systems for wider industrial deployment.

Re-Vector is a modular robotic platform. A common set of joint modules can be assembled in different configurations to create robotic systems with different geometries, reach, manipulability and payload capabilities. Sensors, end-effectors and tooling interfaces can be tailored to individual applications, from confined-space inspection and maintenance to precision handling, machining and additive manufacturing. Electrical cabling, hydraulic lines and pneumatic services can be routed internally through the arm, reducing or eliminating external umbilicals where the configuration permits.

Re-Vector's payload capacity depends on the configuration, reach, operating pose and application requirements. Configurations based on our existing electrically actuated modules have nominal payload capacities in the range of 10–18 kg, subject to the robot geometry and operating conditions. The modular architecture also allows larger-capacity systems to be developed, including bespoke configurations employing electro-hydraulic actuation where higher forces and payloads are required.

Re-Vector's control software is developed within the Robot Operating System (ROS 2) environment, providing a flexible architecture for integration, motion planning and the development of new capabilities. The system uses established robotics tools, including RViz for visualisation and MoveIt for motion planning. Simulation and digital-twin environments support the development, testing and evaluation of robotic configurations and tasks. Re-Vector can be operated by means of programmed motion sequences and teleoperation, with semi-autonomous and increasingly autonomous capabilities being developed for application-specific tasks.

Re-Vector's modular architecture incorporates power and data pass-through, with I/O options that allow sensors, tools and other equipment to be integrated at selected positions along the arm, as well as at the end-effector. POE, USB and power sockets are available at the toolhead. Third-party sensors, actuators and robotic systems can be integrated through appropriate hardware interfaces and the ROS 2 software environment. The platform is designed to accommodate a wide range of application-specific tooling, sensing and control requirements.
