# TempoBridge lets robots follow speed cues in language instructions

> Researchers show a new framework that makes robot actions faster or slower based on tempo words without extra training.

A team led by Yeonseo Lee introduced TempoBridge, a lightweight add‑on for vision‑language‑action (VLA) robot models. It reads tempo cues like “quickly” or “slowly” from the instruction and adjusts motion speed on the fly. The method uses frozen VLA representations, so it needs no extra tempo‑specific demonstrations or fine‑tuning. In tests on the LIBERO benchmark, Tempo Success Rate rose from 52.6% to 89.7% while overall task success stayed high. Real‑world robot trials also showed the system could follow tempo commands.

## The facts

- TempoBridge raised tempo success from 52.6% to 89.7% on LIBERO tasks
- Paper submitted on 7 Oct 2026; published 8 Oct 2026

## Why it matters

It lets end users control how quickly a robot works just by saying “fast” or “slow”, without needing new training data.
