Robots don’t have to be large and imposing to be impressive. As this tiny quadruped from [Dorian Todd] demonstrates, some simple electronics and a few servos can create something altogether charming on their own.
This little fellow is named Sesame. A quadruped robot, it’s built out of 3D-printed components. Each leg features a pair of MG90S hobby servos, one of which rotates the leg around the vertical axis, while the other moves the foot. The ESP32 microcontroller controls all eight servos, enabling remote control of Sesame via its built-in wireless connectivity. Sesame also gets a 128×64 OLED display, which it uses to display a range of emotions.
Mechanically, the Sesame design isn’t particularly sophisticated. Where it shines is that even with such a limited range of motion, between its four legs and its little screen, this robot can display a great deal of emotion. [Dorian] shows this off in the project video, in which Sesame scampers around a desktop with all the joy and verve of a new puppy. It’s also very cheap; [Dorian] estimates you can build your own Sesame for about $60. Files are on GitHub for the curious.
If you prefer your quadrupeds built for performance over charm, you might consider an alternative build. Video after the break.

Tesla is ending Autopilot and steering customers toward higher-priced FSD subscriptions, signalling a major shift in its driver-assistance strategy.
The post Tesla kills Autopilot for good and Musk warns of FSD price hikes appeared first on Digital Trends.
Love it or hate it, Tesla has been responsible for helping to shape the tastes of automotive consumers over the past decade-plus. Over-the-air updates that add more features, an all-touchscreen human-machine interface, large castings, and hands-free driver assists were all introduced or popularized by Tesla's electric vehicles, prompting other automakers to copy them, mostly in the hopes of seeing the same stratospheric gains in their stock prices. But starting on Valentine's Day, if you want your new Tesla to steer itself, you'll have to pay a $99 monthly subscription fee.
Tesla currently offers a pair of so-called "level 2" partially automated driver assist systems. Autopilot is the older of these, combining Tesla's adaptive cruise control (Tesla calls this TACC) and lane-keeping assist (Tesla calls this Autosteer). FSD is the newer system, meant to be more capable and for use on surface streets and divided-lane highways. Although the company and Tesla CEO Elon Musk regularly tout these systems' capabilities, both still require the human driver to provide situational awareness.
But Autopilot has been under fire from regulators and the courts. Multiple wrongful death lawsuits are in the works, and after a high-profile loss resulting in a $329 million judgment against Tesla, expect many of these suits to be settled. Both the federal government and California have investigated whether Tesla misled customers, and in December, an administrative law judge ruled that Tesla indeed engaged in deceptive marketing by implying that its cars could drive themselves. The judge suspended Tesla's license to sell cars in California, a decision that the California Department of Motor Vehicles stayed for 60 days.

Journalists and advocates have been trying to grasp how many victims in total were harmed by Grok's nudifying scandal after xAI delayed restricting outputs and app stores refused to cut off access for days.
The latest estimates show that perhaps millions were harmed in the days immediately after Elon Musk promoted Grok's undressing feature on his own X feed by posting a pic of himself in a bikini.
Over just 11 days after Musk's post, Grok sexualized more than 3 million images, of which 23,000 were of children, the Center for Countering Digital Hate (CCDH) estimated in research published Thursday.

Liquid staking has become a foundational primitive in Proof-of-Stake ecosystems. It allows users to stake assets while retaining liquidity through derivative tokens, removing the need to choose between yield and flexibility. However, most liquid staking systems are still single-chain by design. While users receive a liquid representation of their staked assets, using that liquidity elsewhere often requires manual bridging, fragmented liquidity, and additional trust assumptions.
In a multi-chain ecosystem, this creates friction. Liquidity becomes siloed, and users are forced to actively manage cross-chain exposure rather than letting capital move naturally.
This is the problem space where vUSD on Bifrost is designed to operate.
In this article, we will cover:
Bifrost is designed as a Polkadot parachain, which fundamentally changes how liquid staking assets are issued and utilised.
Instead of creating liquid staking derivatives confined to a single chain, Bifrost introduces voucher tokens (vTokens) as cross-chain financial primitives.
When a user stakes through Bifrost:
Because Bifrost operates as a parachain, these vTokens are designed to move across the Polkadot ecosystem, benefiting from shared security and native cross-chain messaging. Rather than being isolated receipts, vTokens act as portable, yield-bearing collateral. Which naturally leads to the question of how value continues to accumulate once these tokens are in circulation.
Voucher tokens are yield-bearing by design. Staking rewards are continuously reflected in the value of the vToken relative to the underlying asset. Over time:
This embedded yield is a critical property. It ensures that vTokens remain economically active even when they are no longer held in a passive staking position. Because yield continues to accrue, vTokens can safely be reused within DeFi without sacrificing their core purpose.
Once yield-bearing assets become composable, the next requirement is a stable unit of account to unlock more advanced financial use cases.
As DeFi activity grows around voucher tokens, a stable unit of account becomes essential. Stablecoins enable:
Using voucher tokens as collateral for stablecoins allows users to:
Using voucher tokens as collateral for stablecoins allows users to unlock liquidity without exiting staking positions, avoid unnecessary bridging or asset sales, and keep collateral productive while borrowing. This makes over-collateralised stablecoins a natural extension of liquid staking rather than an unrelated financial primitive.
At this point, the design question becomes how borrowing should be structured to preserve safety while leveraging yield-bearing collateral.
Over-collateralised borrowing protocols typically follow one of two models: Maker-style vaults or Liquity-style positions.
Liquity’s design emphasises:
This approach minimises ambiguity and avoids hidden debt dynamics. It is particularly well-suited for yield-bearing collateral, where predictability and transparency are critical. These principles directly inform how vUSD is structured.
vUSD is an over-collateralised stablecoin designed specifically for the Bifrost ecosystem.
Users lock vTokens (such as vDOT) as collateral and mint vUSD based on a predefined collateralization ratio. For example, at a 150% collateral ratio:
Once minted, vUSD can be used across DeFi, swapped, held, or integrated into other protocols while the underlying collateral continues to earn staking rewards. To understand this more concretely, it helps to walk through a simple lifecycle example.
Because minting and burning are explicit actions, the vUSD supply expands and contracts strictly through borrowing and repayment. There is no reflexive supply adjustment or algorithmic minting outside user-driven actions.
This lifecycle also sets the stage for how yield is distributed across the system.
vUSD is yield-backed, not interest-bearing.
Staking yield generated by excess collateral value is shared between:
At the minimum collateralization ratio of 150%:
The yield share for vUSD is defined as:
Yield(vUSD) = vUSD value ÷ (vUSD value + vDOT collateral value)
At minimum collateralization, this results in a 40% yield share.
If collateral prices fall, vUSD’s share is reduced to preserve safety, ensuring yield extraction never weakens collateral backing.
Yield is distributed via rebasing, which increases all vUSD balances proportionally without requiring explicit transfers.
Bifrost’s parachain-native voucher token model enables cross-chain, yield-bearing collateral that remains productive beyond simple staking. vUSD builds on this foundation by introducing a conservative, Liquity-inspired stablecoin designed to unlock stable liquidity while preserving safety and composability.
The current implementation represents a minimal first iteration focused on the core building blocks of the system: voucher-token-backed collateral, explicit borrowing and repayment flows, and a clear over-collateralization model. More advanced components — such as staking yield distribution, liquidation mechanisms, and system-level risk controls — are intentionally not included yet and will be introduced in subsequent iterations.
The full codebase, including the initial contracts, mock voucher tokens, and documented design assumptions, is open-source and available here:
https://github.com/yehia67/vUSD
As the protocol evolves, each major iteration will be accompanied by a follow-up article that documents the new components, design decisions, and trade-offs introduced at that stage. This approach ensures that both the code and the system design evolve transparently, with clear context provided at every step.
