Lauren Martin's Arc

Chapter 5 of 5

Lauren's hands shook as she connected the final wire on her prototype sorting arm. The mechanism whirred to life, its metal fingers opening and closing in smooth rhythm. She'd spent three days building this piece, and now it actually worked. Her tail swished behind her as she placed a small package on the testing platform. The arm's sensors detected the weight, calculated the size, and moved the package to the correct slot. Perfect. She grabbed her blue notebook and wrote down the success, her handwriting messier than usual because she couldn't stop grinning. This was real progress—not just an idea anymore, but something she could touch and demonstrate. If one arm could sort packages this well, a full machine with multiple arms would change everything for the merchants. She set down her pencil and watched the arm complete another cycle, feeling that quiet hope in her chest grow just a little bit louder. The next morning, Lauren carried the sorting arm to the Robco Engineering Museum and Learning Center. The building's blue and gray stone caught the sunlight as she pushed through the entrance doors. Inside, display cases lined the walls, filled with early prototypes from other inventors. Her chest felt tight as she set her sorting arm on the demonstration table they'd given her. A museum worker helped her connect it to power. When the arm activated and began moving packages between slots, three merchants stopped to watch. One asked how fast it could sort. Lauren showed them her notebook logs—the arm processed items twice as fast as manual sorting. The merchants nodded and asked more questions. By the time she packed up to leave, two of them had requested follow-up meetings. Lauren walked outside and spotted a fountain made of glass tubes and brass trim. Water flowed through the tubes in patterns that shifted and changed. She stood watching it for several minutes, her mind racing. The fountain combined old materials with new ideas, just like her sorting arm used salvaged parts and fresh thinking. She pulled out her notebook and sketched the flowing water design. Maybe her next prototype could include visible moving parts—something merchants could watch working, just like this fountain. The idea felt right. On her way back to the workshop, Lauren passed a large clock mounted outside a building. Its glass panels showed the wires and circuit boards inside, and a digital screen displayed numbers that counted down transaction times. She stopped and stared. The clock proved that machines could track business activity in real time. Her sorting arm already recorded package weights and sizes. If she added a timer like this clock had, merchants could see exactly how much faster her invention worked compared to manual methods. Lauren wrote furiously in her notebook, filling two pages with calculations and diagrams. Her prototype had proven the basic idea worked. Now she could build features that showed merchants the actual numbers—the proof they needed to trust her invention. She tucked the notebook back into her belt and headed home, already planning what she'd build tomorrow.
