GestAdapt: Workspace-Conditioned Co-Speech Gesture Generation for Humanoid Robots

GestAdapt is a framework that generates co‑speech gestures conditioned on a specified wrist workspace, allowing humanoid robots to adapt their motions to environmental constraints such as walls. The system learns from six co‑speech corpora using a shared motion representation and can be retargeted to different robot embodiments. Experiments show that GestAdapt’s motions stay close to real‑motion distributions, achieve higher quality scores than a no‑workspace baseline, and outperform other methods in real‑robot evaluations on the Reachy2 humanoid.

Super Star: Towards Streaming Real-time Interactive Agents for Digital Humans

The paper introduces a real‑time framework for generating co‑speech gestures for digital humans, coupling a streaming speech response module with a causal multimodal autoregressive gesture generator that uses only current speech and motion history. It also presents an offline data synthesis pipeline for virtual companion dialogues and a self‑evolving training loop that incorporates user feedback to continually adapt the model. Experiments show the system achieves a better latency‑quality trade‑off, stronger speech‑motion synchronization, and higher user preference than existing baselines.

Auto-HSI: Personalized human control of a robot swarm on demand by using LLMs for online automatic code generation

Auto-HSI is a system that creates personalized human‑swarm interaction interfaces on demand using large language models to automatically generate code from natural language descriptions and gesture demonstrations. The prototype enables untrained operators to control a swarm of 50 simulated robots with one‑ or two‑hand gestures, allowing teleoperation of motion, formation shape, and shape deformation. Experiments demonstrate the system’s gesture tracking, code generation, and live operation capabilities, including real‑time updates and deployment on real robots.

SalsaAgent: A multimodal embodied language model for interactive dance generation

SalsaAgent is a multimodal embodied language model that generates expressive, full‑body salsa follower motions in response to a human leader and music. The approach treats partner interaction as nonverbal token passing, extending a large language model’s vocabulary to include discrete motion, pairwise relation, and audio tokens. A two‑stage token‑to‑diffusion pipeline, combined with full‑body and pairwise‑relation tokenizers and alignment with automatically derived text descriptions of skeleton dynamics, yields improved motion quality, spatial coordination, and music‑partner synchrony compared to prior baselines.

LLM-based Conversational AI Knowledge Assistant for MyBuddy Humanoid Robot

The paper introduces an LLM-based Conversational AI Knowledge Assistant for the Raspberry‑Pi‑powered 13‑Axis MyBuddy humanoid robot. It combines large language model-driven language understanding, real‑time speech recognition, internet‑based knowledge retrieval (e.g., Wikipedia, arXiv), flexible dialogue management, and natural speech synthesis to support intelligent, multi‑turn conversations and emotional‑support interactions. This system aims to overcome the limitations of traditional rule‑based dialogue systems in humanoid robots.

ECHO-G: Embodied Co-speech Humanoid mOtion Generation

ECHO-G is a framework for generating full‑body co‑speech motion for humanoid robots, jointly conditioned on speech audio and timed transcripts. Its Speech‑Grounded Diffusion Transformer (SGDiT) fuses frame‑aligned acoustic features with token‑level linguistic context, preserving distinct granularities while modeling one‑to‑many utterance‑motion relationships directly in robot space. The authors introduce a BEAT2‑derived audio‑text‑robot dataset, a benchmark for co‑speech characteristics, robot‑motion quality, and runtime efficiency, and demonstrate that direct robot‑space generation outperforms human‑motion generation and retargeting pipelines, with joint audio‑text conditioning yielding superior results in both quantitative evaluation and a video‑rating study. "whyItMatters":"The study provides a new dataset, benchmark, and a demonstrably effective method for generating realistic co‑speech motion directly in robot space, advancing practical humanoid robot interaction."
