The Kindalive project by Drew Smith uses a simulated dot-matrix face to express emotions through the modeling of eight key neurochemicals like dopamine and cortisol. Rather than using discrete sentiment labels via LLMs, this approach simulates the organic decay and interplay between chemicals to create fluid mood changes. These emotional states are visually represented through twelve facial movements based on the Facial Action Coding System (FACS).
- Models short-term and long-term moods through neurochemical simulation
- Uses nonverbal communication to increase robot relatability
- Employs 12 elements of the Facial Action Coding System for expression

This research presents penPal, a novel handheld drawing tool designed to support dynamic mark-making and creative decisions at the texture level. By integrating a tendon-driven continuum robot, the device allows its tip to move independently of the user's hand, providing an additional axis of control that combines manual manipulation with computer-assisted generation. Through studies involving participants and professional artists, the work examines how users negotiate multiple coordinate systems—including their own body, the paper, and the tool's tip—to construct complex compositions and explore generative potential through selective defamiliarization.
Key points:
* Use of tendon-driven continuum robots for handheld tools
* Texture-level creative control in drawing
* Negotiation of multiple coordinate systems during composition
* Integration of manual and computer-assisted mark-making

NocKinematics is a modern, modular, and lightweight C++ Inverse Kinematics library designed specifically for Arduino and ESP32 microcontrollers. It utilizes the FABRIK (Forward And Backward Reaching Inverse Kinematics) algorithm to provide fast, iterative computations that are more efficient than traditional Jacobian Matrix approaches. The library is optimized for memory-constrained systems like AVR and ESP8266 by using specialized dynamic memory allocation to prevent RAM fragmentation.
Key features and topics:
* N-Joint Support for arbitrary numbers of connected joints.
* Memory-optimized architecture avoiding heavy std::vector usage.
* Platform agnostic compatibility with Arduino Uno, Nano, Mega, ESP8266, and ESP32.
* Practical implementation examples ranging from basic logic verification to multi-DOF servo motor control.
* Support for complex mechanisms like snake or tentacle simulations via the MultiJointSnake example.
