| # uav-array-codesign |
|
|
| An RL environment for coding agents, in [Harbor](https://harborframework.com) / Terminal-Bench-Science format. The agent designs a 2x2 antenna array for a 2.45 GHz drone radio, then writes a beamforming and link controller that keeps the link up while the drone flies and gets jammed. A physics simulator scores the result, and the reward is 1 only if all 6 tests pass. |
|
|
| ## How it's graded |
|
|
| - Simulator files were not modified |
| - Antenna design meets the matching, isolation, gain and scan targets |
| - Submitted antenna characterization matches the simulator |
| - Controller holds the link on 5 public flight missions |
| - Submitted evaluation summary matches a fresh run |
| - Controller holds the link on 5 hidden missions |
|
|
| Exact thresholds are in the [task README](tasks/engineering-sciences/electrical-engineering/uav-array-codesign/README.md). |
|
|
| ## Built with Beam |
|
|
| We ran Reflection's [Beam-1.0](https://huggingface.co/reflection/Beam-1.0-501B-A23B) as the agent through Harbor's `terminus-2` harness, served by Hugging Face Inference Providers. Its antenna design passed every antenna test, but its controller dropped the link too often: 14 outages on the public missions (limit 10) and 15 on the hidden ones (limit 12). It saw the 14 outages and still declared success. Trajectories and verifier logs are in `jobs/beam-1.0-terminus2/`. |

| | Independent solution | 6/6 | 1.0 | 8 / 7 | |
| | Beam¹ | 4/6 | 0.0 | 14 / 15 | |
| | DeepSeek V4.1 Flash | 3/6 | 0.0 | 27 / 19 | |
| | Starting baseline | 1/6 | 0.0 | 584 / 551 | |
