Curiosity-Driven Co-Development of Action and Language in Robots Through Self-Exploration (2510.05013v1)
Published 6 Oct 2025 in stat.ML and cs.LG
Abstract: Human infants acquire language and action co-developmentally, achieving remarkable generalization capabilities from only a minimal number of learning examples. In contrast, recent LLMs require exposure to billions of training tokens to achieve such generalization. What mechanisms underlie such efficient developmental learning in humans? This study addresses this question through simulation experiments in which robots learn to perform various actions corresponding to imperative sentences (e.g., \textit{push red cube}) via trials of self-guided exploration. Our approach integrates the active inference framework with reinforcement learning, enabling curiosity-driven developmental learning. The simulations yielded several nontrivial findings: i) Curiosity-driven exploration combined with motor noise substantially outperforms learning without curiosity. ii) Simpler, prerequisite-like actions emerge earlier in development, while more complex actions involving these prerequisites develop later. iii) Rote pairing of sentences and actions occurs before the emergence of compositional generalization. iv) Generalization is drastically improved as the number of compositional elements increases. These results shed light into possible mechanisms underlying efficient co-developmental learning in infants and provide computational parallels to findings in developmental psychology.

What is this paper about?
This paper explores how a robot can learn actions (like moving and pushing) and language (understanding short spoken commands) at the same time—much like a baby does—by exploring on its own. Instead of being shown millions of examples, the robot teaches itself through curiosity and a bit of randomness, and it learns to understand and do new things from just a small number of examples.
What questions were the researchers asking?
The team wanted to know four simple things:
- Does curiosity (wanting to see new, surprising outcomes) plus a bit of randomness in movement help a robot learn faster and better?
- Do simple actions get learned before complex ones that depend on the simple ones?
- Do robots first memorize exact phrases before they can understand new sentence combinations made from familiar words?
- If you give the robot more “building blocks” of language (more verbs, colors, and object types), does it become better at understanding new sentences it hasn’t heard before?
How did they paper it?
The robot and its world
They used a simulated robot that looks like a tiny truck with an arm. It has:
- Two wheels to move around
- An arm with two joints to reach and push
- A small camera (for vision), touch sensors, and sensors that tell it the positions of its arm joints (proprioception)
- A speaker/microphone channel for hearing the command and feedback “voices”
In each trial, the robot hears a short spoken command like “push left green cone” or “watch red pillar.” The world has two objects with different shapes and colors. The robot gets a reward if it achieves the command (for example, actually pushing the green cone to the left).
The commands are built from:
- Verbs (actions): watch, be near, touch the top, push forward, push left, push right
- Adjectives (colors): red, green, blue, cyan, magenta, yellow
- Nouns (objects): pillar, pole, dumbbell, cone, hourglass
That creates many possible sentences (compositions). Importantly, the robot practices on only one-third of all possible sentences and is tested on the other two-thirds to see if it can generalize.
How the robot “thinks”: two key ideas in simple terms
- A forward model (imagination): This part tries to predict what the robot will see/feel next if it takes a certain action. Think of it like the robot’s inner “what will happen if I do this?” simulator.
- An actor-critic (decision-maker and coach): The actor chooses what to do next; the critic scores how good that choice was.
These parts work together as the robot explores. The robot learns from two kinds of rewards:
- Extrinsic reward: a “good job” when it actually completes the commanded task.
- Intrinsic rewards: built-in motivations that make the robot an eager learner:
- Curiosity: the robot is rewarded for actions that lead to surprising or informative experiences (new sights or touches it didn’t expect).
- Motor entropy: the robot is encouraged to keep a little randomness in its movements so it doesn’t get stuck doing the same thing over and over.
You can think of this as a smart balance: the imagination tries to reduce surprise by getting better at predicting the world, while the actor sometimes seeks out surprise to discover new things. This “friendly tug-of-war” pushes learning forward quickly.
What experiments did they run?
- Curiosity levels: They tried three settings—no curiosity; curiosity only for body senses (vision, touch, arm position); and curiosity for everything (including the feedback voice).
- Learning vs. generalization: They trained on 33% of the sentences and tested on the remaining 67% to see how well the robot handled new combinations of familiar words.
- Scale of compositions: They repeated experiments with smaller sets of verbs/colors/objects to see how vocabulary size affects generalization.
They also looked inside the robot’s learned representations (like checking its “mental map” of tasks and colors) and tested whether it could “mentally plan” by predicting the future without looking (like a short daydream of what will happen next).
What did they find? Why is it important?
Here are the main findings, followed by why they matter:
- Curiosity + a bit of randomness makes a big difference.
- With full curiosity across senses, the robot reached about a 90% success rate on new, untrained sentences—even though it had seen only one-third of all possible sentences in training.
- This shows that smart exploration can replace huge amounts of brute-force data.
- Simple actions come first; complex ones come later.
- The robot learned “watch” (look at the object) and “be near” (approach the object) early.
- Harder actions like “push left/right” and “touch the top” came later.
- That’s exactly how humans build skills: basics first, then combinations.
- First memorization, then real understanding.
- Early on, the robot could do tasks only for sentences it had heard exactly.
- Later, it could do tasks for new sentences made from familiar words (for example, handling “push right yellow pole” even if it only ever practiced “push right blue pole”).
- This mirrors how children move from rote learning to flexible, compositional understanding.
- More “Lego bricks” lead to better generalization.
- When the set of verbs/colors/objects was bigger, the robot generalized much better.
- This suggests that the number of examples you need is closer to “the sum of parts” than “every possible combination,” a key idea in explaining how kids learn so much from so little.
- The robot can “plan in its head” when well trained.
- After full training, it could complete tasks using mostly its own predictions, almost like mentally simulating the future. Halfway through training, this didn’t work well yet.
- This shows its internal world model became accurate and useful for planning.
- Curiosity helps the robot organize knowledge clearly.
- When they peeked into the robot’s internal representations, the “curious” robot had neat clusters for different tasks and colors (like tidy folders), while the “no curiosity” robot’s knowledge was tangled and confusing.
- Clean, well-separated concepts are key for strong generalization.
Why this matters: These results suggest that curiosity, structured exploration, and compositional language help machines learn efficiently like children do—without needing billions of examples. That’s a big step toward AI that learns more like humans.
What could this mean for the future?
- Smarter, data-efficient robots: Robots could learn new tasks from a few demonstrations or even from simple spoken instructions, becoming useful faster and with less training data.
- Better AI learning strategies: Mixing curiosity with a little controlled randomness may help other AI systems explore and understand the world more effectively.
- Insights into human development: The paper offers a computational explanation for how children might learn language and action so quickly—by exploring, mastering simple skills first, and building up complex abilities from reusable parts.
Limitations and next steps
Right now, the “tutor” talks to the robot, but the robot doesn’t talk back to ask for help or clarification. A future version could include real two-way teaching (like a child asking, “Can you show me an easier one?”). Another exciting direction is having multiple robots develop their own shared, action-focused language through interaction, not just labels for objects.
In short, this research shows that curiosity-driven self-exploration, combined with building-block language, can teach robots to act and understand in a human-like, efficient way.
Knowledge Gaps
Knowledge gaps, limitations, and open questions
Below is a single, consolidated list of what remains missing, uncertain, or unexplored in the paper. Each point is phrased to be concrete and actionable for future research.
- Real-world validation: All results are in a simplified physics simulator with low-resolution vision (16×16) and constrained kinematics. It remains unknown whether the approach transfers to real robots with noisy sensors, richer visuals, higher-DOF manipulators, and unmodeled dynamics.
- Baselines and controls: The paper varies curiosity across modalities but lacks:
- A pure-entropy baseline (curiosity off, entropy on) to quantify the added value of curiosity.
- A pure-curiosity baseline (entropy off) to quantify the added value of entropy.
- Comparisons to common intrinsic motivation methods (e.g., RND, ICM, count-based novelty, empowerment) and to RL-only or AIF-only variants.
- Tutor feedback confound: The agent receives “feedback voice” labeling whichever goal was achieved, even when it differs from the command. The performance gain under “all curiosity” (including curiosity over feedback voice) may exploit this strong supervisory signal. An ablation isolating the effect of feedback voice and its curiosity term is missing.
- Compositional generalization scope: Generalization is tested only over new combinations of known words (verbs/adjectives/nouns). The system’s behavior with:
- Out-of-vocabulary words (novel verbs/adjectives/nouns),
- Synonyms/polysemy, morphological variants, and paraphrases,
- More complex syntax (multi-clause commands, quantifiers, pronouns, negation),
- remains untested.
- Training fraction sensitivity: All experiments use one-third of compositions for training. The effect of varying the training fraction (e.g., 10–80%) on generalization and learning dynamics is unexplored.
- Scaling laws and sample complexity: The paper hypothesizes a sum-of-elements scaling in sample complexity but does not empirically assess scaling laws across much larger vocabularies, longer horizons, or broader task families. Quantitative fits (e.g., power-law or logarithmic scaling) are missing.
- Hierarchical prerequisites: The observed emergence of “watch” → “be near” → “manipulate” is correlational. Causal tests (e.g., curriculum manipulations, withholding prerequisites, or explicit dependency control) are needed to verify prerequisite relations and their necessity/sufficiency.
- Hyperparameter sensitivity: The roles of curiosity weight n, entropy weight α, discount γ, episode length, replay buffer parameters, and SAC-specific settings are not systematically analyzed. Robustness across seeds and hyperparameters beyond n=10 agents is unclear.
- Stability of the “racing” dynamics: The paper notes that minimizing evidence free energy (F) reduces complexity while minimizing expected free energy (G) increases it, leading to a “race” between learning and exploration. There is no theoretical or empirical analysis of stability, convergence, or potential limit cycles/oscillations in this coupled system.
- Policy-level interpretability: Beyond PCA visualizations of latent command representations, there is no analysis of the learned policy structure (e.g., state-action abstractions, option discovery, or hierarchical control) or causal links between latent representations and behavior.
- Prediction quality and planning metrics: “Mental planning” is demonstrated qualitatively. Quantitative measures of prediction accuracy (vision/tactile/proprioception), planning horizon, error accumulation, and how predictive accuracy correlates with task success are missing.
- Environment complexity: Tasks are performed with only two objects in the arena and simple color/shape vocabularies. The approach’s robustness to:
- More distractors/objects and clutter,
- Occlusions, partial observability, and domain randomization,
- Non-stationary environments,
- is not evaluated.
- Reward design and constraints: Success criteria are hand-crafted and include constraints (e.g., speed limits during push-left/right). The sensitivity of learning to these reward definitions, and the consequences of reward noise or sparse/delayed rewards, are not explored.
- Voice modality representation: Details of how “command voice” and “feedback voice” are encoded/decoded (e.g., acoustic vs. symbolic, tokenization) are not specified. The effect of realistic speech variability, noise, and ASR errors on learning is unknown.
- Modality-specific curiosity: While curiosity is computed per modality, the relative contribution of each modality’s KLD term (vision, tactile, proprioception, command voice, feedback voice) to exploration and generalization is not disentangled or measured.
- Cross-task transfer: The agent is trained/tested in a single domain (mobile arm with color/shape-directed commands). Whether internal models or policies transfer to new task families (e.g., different manipulators, spatial prepositions, tool use, temporal sequencing) is untested.
- Safety and physical constraints: Exploratory behavior under curiosity may induce unsafe actions on real robots. Strategies for safe exploration (e.g., constraint-aware curiosity, risk-aware EFE) are not addressed.
- Language grounding breadth: Adjectives are limited to colors, and nouns to shapes. Grounding richer adjectival properties (size, texture), relational terms (left-of, behind), and verb classes (lift, stack, rotate) is untouched.
- Curriculum and tutor strategies: The paper suggests interactive scaffolding as a future direction but provides no concrete mechanisms to adapt curricula or tutor policies based on the robot’s competence, nor metrics for evaluating tutor-robot co-adaptation.
- Generalization under distribution shift: The agent’s behavior under shifts in language distributions (e.g., change in verb frequency or adjective-noun correlations) and environmental distributions (object placements, dynamics) is not examined.
- Credit assignment across modalities: The RL signal blends extrinsic reward with modality-specific intrinsic rewards. There is no analysis of how credit assignment is handled across modalities or whether interference (e.g., voice curiosity dominating vision curiosity) occurs.
- Alternative formulations of expected free energy: The implementation uses Gaussian latent distributions and a particular decomposition of EFE. The impact of non-Gaussian latent models, different priors, or alternative decompositions (e.g., risk vs. ambiguity) on performance is unknown.
- Data efficiency and compute costs: The paper reports epochs but does not quantify data efficiency (episodes to reach given success rates), wall-clock training time, or compute requirements, making it difficult to compare to other methods and to assess practical feasibility.
- Failure modes and error analysis: There is no systematic taxonomy of failure cases (e.g., misinterpretation of commands, object mislocalization, manipulation errors) or targeted interventions to remediate them.
- Reproducibility details: Although code is shared, the paper does not report comprehensive configuration details (random seeds, hardware, exact hyperparameters per run), which are needed for reproducible benchmarking.
- Ethical and developmental claims: Connections to infant learning and “poverty of the stimulus” are suggestive but not formally tested. Behavioral benchmarks grounded in developmental psychology (e.g., standardized tasks for compositional generalization in infants) would strengthen these claims.
- Long-horizon, multi-step instructions: Commands are single-step imperatives. The ability to follow multi-step, temporally extended instructions (e.g., “go near the blue cone then push it right”) and to maintain plans over longer horizons is not investigated.
