Affordances are key attributes of what must be perceived by an autonomous robotic agent in order to effectively interact with novel objects. Historically, the concept derives from the literature in psychology and cognitive science, where affordances are discussed in a way that makes it hard for the definition to be directly transferred to computational specifications useful for robots. This review article is focused specifically on robotics, so we discuss the related literature from this perspective. In this survey, we classify the literature and try to find common ground amongst different approaches with a view to application in robotics. We propose a categorisation based on the level of prior knowledge that is assumed to build the relationship among different affordance components that matter for a particular robotic task. We also identify areas for future improvement and discuss possible directions that are likely to be fruitful in terms of impact on robotics practice.

Token-Based Affordance Grounding with Large Vision-Language Models
TokAG selects the LVLM output token whose aggregated cross-attention is most concentrated on a CLIPSeg object mask, converting that map into a zero-shot affordance heatmap that outperforms weakly supervised baselines.

Affogato: Open-Vocabulary Affordance Grounding with Automated Data Generation at Scale
A fully automated pipeline using Gemma, Molmo, and SAM generated 750K open-vocabulary 3D affordance annotations on 150K Objaverse objects, and models trained on them transfer to unseen categories.

AffordanceSAM: Segment Anything Once More in Affordance Grounding
Adapting EVF-SAM with learnable affordance queries and a coarse-to-fine dataset yields strong affordance grounding on AGD20K, with caveats about test-set tuning.

AffordDP: Generalizable Diffusion Policy with Transferable Affordance
A diffusion-based manipulation policy conditioned on transferred 3D contact points and post-contact trajectories, with adaptive affordance-guided sampling, generalizes to unseen object instances and categories.
