RARL78

RARL78 is a fictional humanoid robotics platform used in theoretical discussions and educational demonstrations to illustrate modular automation and human-robot collaboration. The model is described as being developed by the fictional company Orion Dynamics as a successor to an earlier model, RARL72.

Design and architecture: The platform features a 1.75 m tall humanoid frame, 130 kg mass, with two 7-DOF arms; a 3-DOF torso for yaw and pitch; a dexterous hand with a four-finger gripper; end-effectors can be swapped to suit task requirements. The design emphasizes modularity, easy tool interchange, and easy maintenance.

Systems and control: Actuation relies on series elastic actuators to provide force feedback and compliance. The control architecture is distributed, with an onboard computer running ROS 2 for perception, planning, and manipulation tasks. Perception is supported by stereo cameras, a depth sensor, proprioceptive joint encoders, tactile sensing in the hands, and an optional LiDAR module for environment mapping.

Power and safety: The platform is powered by a 1.5 kWh lithium-ion battery, offering typical endurance around four hours under moderate workloads; recharge time is approximately two hours. Safety features include torque sensing on all joints, an emergency stop, and software-level collision avoidance to enable smooth human-robot collaboration.

Variants and usage: Noted variants include RARL78-A and RARL78-E, differing in payload capacity, sensor suites, and processing power. In its fictional context, RARL78 is used for demonstrations in manufacturing automation, warehouse logistics, disaster-response prototyping, and robotics research.
