StrengthsExcellent ArchitectureFile: Positive: Clean separation between API, model, and hardware layers. Good use of factory patterns and proper abstraction. Comprehensive Mock ImplementationFile: Positive: Well-implemented mock mode for development and testing without hardware. Good Testing CoverageFile: Positive: Excellent test suite with platform-agnostic tests and performance validation with and without hardware. Areas for Improvement❌Missing Setup FilesIssue: The Suggestion: Create a New File: litserve>=0.1.0
torch>=2.0.0
transformers>=4.30.0
opencv-python>=4.8.0
numpy>=1.24.0
git+https://github.com/huggingface/lerobot.gitThis approach provides: ❌Docker Image Configuration MismatchFile: Issue: The config declares multiple platform images for LeRobot that doesn't exist lerobot:
images:
nvidia: "getsolo/lerobot:cuda"
amd: "getsolo/lerobot:rocm"
apple: "getsolo/lerobot:arm"
cpu: "getsolo/lerobot:cpu" Reality: Only one Dockerfile exists: Suggestion: Update config to reflect actual available images: lerobot:
default_model: "lerobot/act_so101"
default_port: 5070
container_name: "solo-lerobot"
images:
default: "getsolo/lerobot:latest" # ✅ Single image for all platformsDevice Detection EnhancementFile: Issue: Basic device detection without platform awareness. Suggestion: Enhance with comprehensive device detection: def setup(self, device):
"""Platform-aware device detection"""
import platform
# Enhanced device detection
if str(device).lower() in ["cuda", "0"] and not torch.cuda.is_available():
if torch.backends.mps.is_available():
device = "mps"
elif hasattr(torch.backends, 'vulkan') and torch.backends.vulkan.is_available():
device = "vulkan"
else:
device = "cpu"
# Validate device availability
try:
if device == "cuda":
torch.cuda.get_device_properties(0)
elif device == "mps":
torch.zeros(1, device="mps")
elif device == "vulkan":
torch.zeros(1, device="vulkan")
except Exception as e:
print(f"Device {device} not available, falling back to CPU: {e}")
device = "cpu"

"windows": {
"mock_hardware": False,
"robot_port_pattern": "COM*",
"device_mounting": False,

OS Platform Check MissingIssue: File: Platform IntegrationFolder: Suggestion: Move LeRobot to the package folder and use native execution for ALL operating systems to eliminate cross-platform compatibility issues: Benefits of Native Execution for All Platforms: ✅ Recommendation: Approve with Minor ChangesThe LeRobot integration is well-structured and aligns with Solo Server conventions. The core implementation is solid, most issues are related to documentation gaps and platform setup, not logic or design. With the following minor improvements, this PR will be ready to merge: 🔧 Priority Fixes
Note: While I haven't tested the code with actual robot hardware on my windows machine, I have extensively reviewed the implementation and performed comprehensive mock testing to validate the integration points and API functionality. |

Title
feat: Add LeRobot robot control support to Solo Server
Description
Summary
This PR adds LeRobot integration to Solo Server, enabling one-command deployment of robot control policies for the SF Bay Area Robotics Hackathon (June 14-15, 2025).
Key feature:
solo serve -s lerobot -m lerobot/act_so101now deploys a robot control server in seconds!What Changed
