Tesla's '2.5 gen' Optimus humanoid stumbles through its first demo

Tesla recently showcased an updated version of its Optimus humanoid robot, dubbed "version 2.5," clarifying that this iteration is an intermediate upgrade rather than a new generation. The gold-colored robot demonstrated limited real-world capabilities in a brief demo featuring xAI’s Grok voice assistant. During the demo, the robot responded hesitantly to voice commands and walked slowly, with Elon Musk noting it was still cautious about spatial awareness and would eventually move faster. Despite these incremental improvements, the robot showed little evidence of advanced autonomy or dexterous manipulation, and the video ended before any object retrieval was attempted. Visually, Optimus 2.5 features a smoother, more cohesive exterior with rounded edges, better-covered joints, and fewer visible seams and wires, marking a shift toward a more human-like silhouette. These design refinements aim to enhance both the robot’s mobility and its readiness for human environments. Tesla continues to emphasize Optimus as a key part of its long-term strategy, pairing
