🚀 Getting Started

Prerequisites

• Rust
• rerun-cli

Installation from Crates.io

cargo install rerun-cli
cargo install peng_quad
peng_quad config/quad.yaml

Installation from Source

cargo install rerun-cli
git clone https://github.com/makeecat/Peng.git
cd Peng
cargo run --release config/quad.yaml

⚙️ Configuration

• You can configure the simulation through config file, see quad.yaml for example.
• Configure simulation parameters such as mass, inertia, and control gains.
• Configure control parameters such as PID gains.
• Configure trajectory planner parameters such as waypoints, obstacles, and trajectory type.
• Configure visualization parameters such as camera intrinsics and depth rendering.

🔧 Rerun Troubleshooting

If you encountered any issue with the rerun:

1. Verify rerun-cli version matches rerun version in Cargo.toml:

rerun --version

2. For Linux/WSL2 users, consult the rerun troubleshooting.

🗺️ Roadmap

• Wind field and environmental effects
• Motor dynamics simulation
• Multi-quadrotor simulation
• Model Predictive Control (MPC)
