Tau Robotics, a San Francisco startup, has launched a humanoid-robot cleaning service. Its long-term goal is autonomous cleaning robots, but the technology isn't ready yet. For now, humans pilot the machines remotely through onboard cameras. A reporter who tried the service found unexpected challenges, along with glimpses of a future with domestic robots. Meanwhile, Samsung is building a vast semiconductor campus in Pyeongtaek, South Korea, south of Seoul, to meet soaring demand for the memory chips that generative AI models rely on. Three fabs already run around the clock, a fourth is coming online, and thousands of workers are racing to build a fifth.

Samsung has added stablecoin accounts to Samsung Wallet, letting eligible US Galaxy users buy, hold, send, and receive Circle's USDC on the Solana blockchain. The feature went live on Thursday and needs no separate crypto app or private key management. It reaches about 82 million compatible Galaxy devices in the US. The product is built with Bastion, a licensed stablecoin custodian, and Coinbase, which safeguards the USDC as sub-custodian. Samsung stresses that the account is a crypto wallet, not a bank account. Transfers to other Samsung Wallet users and compatible outside wallets carry no Samsung fee. Topping up by credit card costs 4%, and new users who top up $50 or more can receive $25 in USDC. The service requires Android 13 or later and is open to US residents aged 18 and older, except those in New York.

Samsung Electronics is reportedly preparing to make memory chip components for AMD and Nvidia at its second Texas plant, Reuters reported, citing South Korea's Maeil Business Newspaper. The plant has orders for all planned output, most of it for AMD. The factory will produce base dies for high-bandwidth memory chips used in AI processors. It will use Samsung's 2-nanometre process. The plant will cover about 2.7 million square feet, roughly 1.5 times the size of Samsung's first Texas plant. Construction begins this month, with production due in 2030. The first plant has a $16.5 billion agreement with Tesla, signed in July 2025, to make its next-generation AI chips.
