About RobotCrash

What RobotCrash Is

RobotCrash is an independent, advertising-supported site about robotics, AI, and automation, paired with a small set of free browser-based developer tools and a Robots & AI Museum. It isn’t affiliated with any robot manufacturer, AI lab, standards body, or brand it happens to write about.

How the Tools Are Built

Every tool under Toolsruns entirely in your browser — nothing you type or paste is sent anywhere. Each one wraps a specific, checkable method rather than a black box:

• Base64 Encoder / Decoder uses the standard Base64 alphabet and round-trips through TextEncoder/TextDecoder, so UTF-8 text — accents, CJK, emoji — survives intact.
• JSON Formatterparses input with the browser’s own JSON parser, re-serializes it with 2- or 4-space indentation, and surfaces that parser’s own error the moment something is malformed.
• Hash Generatorcomputes SHA-1, SHA-256, and SHA-512 with the browser’s native Web Crypto API (crypto.subtle.digest). MD5 has no Web Crypto equivalent, so it runs a small, classic RFC 1321 implementation instead. All four digests are computed locally.
• Color Converter applies the standard HEX, RGB, and HSL conversion formulas and renders a live swatch, so you can check the result by eye as well as by number.
• File Size Converterconverts side by side on the two scales people mix up constantly: decimal SI units (KB, MB, GB, TB — powers of 1000) and binary IEC units (KiB, MiB, GiB, TiB — powers of 1024), plus the exact byte count.
• IP Address Lookupvalidates IPv4 and IPv6 syntax and classifies version, class, and private/loopback/link-local/multicast ranges directly from the address itself — no external lookup service or API call involved.
• Password Generator draws from crypto.getRandomValues(), the browser’s cryptographically secure random source, rather than Math.random(), across whatever length and character sets you choose.
• Regex Tester runs your pattern through the actual JavaScript regular-expression engine, lets you toggle the g/i/m/s flags, and lists every match with its index and capture groups.

The Robots & AI Museumworks differently: it’s a set of galleries on the history of robotics, AI, and automation, and every entry, image, and fact in it is drawn from Wikipedia and Wikimedia Commons rather than written from scratch. Related background reading lives on the blog and in the learn section.

What This Is — and Isn’t

RobotCrash is a small, independent site kept running by advertising, not a company with a support desk, a research team, or a published track record. The tools above are deterministic, general-purpose utilities: their output depends entirely on what you feed in, and it is general informational content, not professional engineering, security, or legal advice. Verify anything safety-critical or production-bound independently.
