🤖 Simulation-First Robotics
Don’t risk your hardware on untested code. SPDR Bot is engineered for a digital-twin workflow. Train your walking algorithms in NVIDIA Isaac Sim using reinforcement learning before ever touching the real robot.
- URDF Ready: Perfectly defined joints for physics engines.
- Reinforcement Learning: Learn to walk, crawl, or recover from falls in simulation.
- OpenRoboticPlatform (ORP): Designed following standard rules for maximum interoperability.
⚙️ High-Performance Hardware
A walking robot requires precision. Every joint has been optimized for high-torque 25kg servos and a sturdy, lightweight FDM-printed frame.
- 12-Servo Locomotion: 3 Degrees of Freedom (DoF) per leg for fluid, lifelike movement.
- Modular Brain Bay: Spacious chassis fits Jetson Nano, Raspberry Pi, or Pico controllers.
- Easy Maintenance: Standard screw assembly with no exotic tools required.
