Unveiling Sparky: A New Chapter in Airsoft Robotics
Hello fellow airsofters! Welcome to the premiere installment of our series, delving into the evolution of Sparky, a formidable Northrop Grumman Andros Wolverine bomb disposal robot turned into an unmanned airsoft combatant. Here at Barbarian Airsoft, we're excited to embark on this journey of technical ingenuity and tactical innovation, pushing the boundaries of what's achievable in the realm of airsoft robotics.
Sparky Overview
Let's dive into the intricacies of Sparky's design. Equipped with a towering 8 feet long arm and with the ability to conquer stairs at a 45-degree incline, Sparky is no ordinary robot. However, beneath its imposing exterior lies a relic of outdated technology. The onboard computer system, equipped with circuit boards dating back to 2001, presented a significant obstacle. This prompted us to modernize the system. Out went the obsolete circuitry, replaced by Raspberry Pis and Arduino boards, breathing new life into Sparky and equipping it for the challenges ahead.
But the surprises didn't end there. During our research of Sparky, we discovered a once-integrated radio module, offering remote control capabilities that had since been removed. As we peel back the layers of Sparky's past, we're determined to recreate this essential feature, enhancing Sparky's versatility on the battlefield.
Adding to the intrigue are the numerous cameras adorning Sparky's frame. These cameras hold the promise of augmenting Sparky's situational awareness and remote monitoring capabilities, providing invaluable insights into the battlefield dynamics. However, unlocking their full functionality remains a puzzle waiting to be solved, a challenge we eagerly embrace as we push the boundaries of what's possible with Sparky.
The Challenge
Upon acquiring Sparky, we were confronted with a challenge: revitalizing a machine that had been dormant for nearly a decade. Yet, where others might have seen obsolescence, we recognized untapped potential. In just a few short months, we've made significant strides in reviving Sparky. We've replaced its batteries, powered it on, and verified the functionality of its limbs. However, our mission is far from complete.
At present, we find ourselves immersed in the process of troubleshooting Sparky's remaining issues. While two of its six motors are operational, the remaining four remain inert. Our current focus is to diagnose the underlying causes of their malfunction, whether it be defective motors, disconnected connectors, or other technical anomalies within the system.
The Plan
To guide our efforts, we've devised a comprehensive plan of action, outlining the necessary steps to fully operationalize Sparky:
- Remove wheels and access motors.
- Identify and rectify issues with non-functional motors, procuring replacements as needed.
- Ensure the functionality of all motor controllers, replacing any that are defective.
- Conduct thorough testing of all arm motors, documenting their inputs and outputs.
- Validate the performance of all arm motors.
- Employ an Arduino Mega and relay board to develop control mechanisms for Sparky's movement via remote controller.
- Replicate the programming process for controlling the arm.
- Implement long-range hobby RC control capabilities. Install FPV cameras and splitters to facilitate remote monitoring and control.
- Select and integrate an airsoft gun/system onto Sparky's arm, engineering an adapter for seamless compatibility with the gripper module.
As we embark on this ambitious endeavor, we invite you to follow along with us, as we document Sparky's progress and advancements. Stay tuned to our blog for regular updates on Sparky's journey, as we endeavor to redefine the possibilities of airsoft robotics, one innovation at a time. Together, let's push the boundaries of what's achievable with Sparky and Barbarian Airsoft at the helm.
