It provides seven actuator classes ranging from simple stateless PD controllers to stateful PID, delayed PD, DC motor models, and neural network actuators (MLP and LSTM). Each actuator reads from simulation state arrays and writes computed forces back to control arrays, with support for both CUDA-graphable and non-graphable execution paths.\n\nThe library is built on top of warp-lang for GPU acceleration and optionally integrates PyTorch for neural network actuators. However, the package is now deprecated: starting with Newton 1.3, all actuators have been moved into the main newton package as newton.actuators, and this standalone distribution is no longer maintained. Existing users should migrate to the built-in module.","worth_installing":"No\u2014do not install. The package is explicitly deprecated and unmaintained as of Newton 1.3. The same functionality is now available in the main newton package as newton.actuators. Migrate to that instead to receive ongoing maintenance and updates."},"id":"newton-actuators","links":{"html":"https://skillfed.io/packages/newton-actuators","md":"https://skillfed.io/packages/newton-actuators.md","pypi":"https://pypi.org/project/newton-actuators/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-05-29","license_spdx":"Apache-2.0","license_treatment":"permissive","name":"newton-actuators","python_support":"supports_current","summary":"DEPRECATED: actuators are now part of the 'newton' package as 'newton.actuators'.
