About this file
This document is a Sources Sought Notification for a Robotic Asset Characterization System (RACS) by the Naval Research Laboratory, detailing specific robotic arm use cases and requirements. The use cases span three scenarios involving precise payload manipulation, including adversarial simulation, field positioning of assets, optical characterizations, hardware-in-the-loop functions, and source/sensor alignment. Key technical requirements include arms that can be moved within labs and remote test facilities, handle payloads ranging from 20 to 100 lbs, provide 6-axis rotation and translation, operate at various rotation angles (±45° to ±90°), and function with 110 VAC power. The arms must have safety proximity sensors, require programming and maintenance training, and will be used exclusively indoors or within shelters across diverse scientific and research applications.

Robotic Asset Characterization System SSN No.: N0017325SSNML01 Sources Sought Notification Attachment 02 – Use Cases
NRL Robot Arm Use cases Payload – what arm is expected to hold or manipulate Use case: Company will provide example of first use case and train us to implement use case Requirements:
• Arms must be able to be moved within the lab and remote test facilities.
• Use case will define a range of motion – more weight = less range
• Repetitive accuracy will vary but needed for all use cases
• While 220V is available in many cases, 110 VAC is preferred
• Safety proximity sensor will be needed
• Arm motion programming and maintenance training
• All use cases will be indoors or within shelters
Use Cases Scenario One:
1. Adversarial simulation: Holding target sources steady while tested at range. These arms will be used as a Robotic Asset Characterization System (RACS) to perform precise, customizable, and reproducible measurements of a wide variety of assets with varying sizes and shapes.
2. Field positioning of assets: Accurately and reproducibly orient assets over a wide range of rotation angles (> ±45°) in both azimuth and elevation, translate these assets laterally over several meters, and provide roll adjustments to quantitatively assess cylindrical asymmetries. That is, the RACS needs to have 6-axis rotation and translation with an additional long-range (> 1 meters) translation dimension.
The RACS need to have a weight range from 0 -77 to 100 lbs.
3. Optical characterizations: Should be able to hold a 70 lb. payload and rotate (in Az/El) +/- 90 degrees. For this application, resolution is not critical. What is more critical is repeatability. Data sets would ideally be taken in various spectral bands, so the ability to replicate the tests with pixel level accuracy would be preferred.
Use Cases Scenario Two:
1. Hardware in the loop function: Holding up to a 70lb payload. Movements will be in multiple axes with a relatively small range of translation.
2. Dual arm asset perturbation: Two arms will move a suspended asset. The asset’s weight will be held by a gantry system. The arms will move the payload in concert to achieve flight azimuth, elevation, roll and acceleration/deceleration profiles.
3. In Field test Payload flight profile simulation: Arm will hold up to 70 lb. payload and operate under control of simulated response to externally generated stimulus. Arm must be mobile and able to be lifted by hoist and then installed (on either cart or floor) in a room at the top of a fire tower.
Use Cases Scenario Three:
1. Large optic alignment: Two arms will move the optical axis of a source to sensor optical system.
Each arm will hold a 12” diameter, protected-silver coated, flat mirror (20 lbs.) payload. Arms will maneuver to direct light between a source and a sensor, where source and sensor are in fixed positions within the lab.
2. Source/ Sensor Alignment: Similar payloads and use cases as Use Case Scenario One and Use Case Scenario Two. Arm to be utilized in the lab or in the Mobile Lab (back of semitruck).
