Rex: A Single-board Computer With A Full OS That Is Designed For Robots

From the Rex Kickstarter:

Why do you want Rex?

There are two general classes of electronics used in robot hardware: microcontrollers (ex. Arduino) and single-board computers. Microcontrollers are great for projects that only require a single program to be run, quickly and without overhead, like controlling LEDs and motors. Single-board computers are great for anything you'd need a cheap, small computer for - like networking applications and image processing.

Advanced autonomous robots require the strengths of both. A system developed around Rex, being made specifically for robots, brings it all together in one nice little package in a way that has never been done before.

Hardware Specs:

  • Texas Instruments DM3730
  • 1GHz 32-bit ARM Cortex-A8 Processor core
  • 800MHz DSP core
  • 512MB LPDDR RAM
  • USB Host port
  • MicroSD slot
  • Camera Module port
  • 3.5mm Audio-in jack
  • 3.5mm Audio-out jack
  • 5V DC input for desktop development

Each Rex will come pre-installed with Alphalem OS, a FOSS custom linux distribution. It includes a core set of built-in device drivers - ones that we've hand-picked as being the most useful for robots (like USB WiFi adapters and cameras). We'll publish the list in a wiki on our website.

Here are the other main features:

  • An Arduino-style programming environment with support for multiple programming languages (C, C++, Python).
  • A special task manager called the Master Control Program (MCP).
  • An API for message passing in multi-process applications.
  • A standard Linux filesystem which will allow you to install just about any Linux software that can be cross-compiled for ARM.
  • Libraries for common processes such as I2C communication, face detection, and sensor reading.

Robotic Tool Changers Increase Productivity and Reduce Cost

Robotic Tool Changers Increase Productivity and Reduce Cost

The ATI Robotic Tool Changer provides the flexibility to automatically change end-effectors or other peripheral tooling. These tool changers are designed to function reliably for millions of cycles at rated load while maintaining extremely high repeatability. For this reason, the ATI Tool Changer has become the number-one tool changer of choice around the world. ATI Tool Changer models cover a wide range of applications, from very small payloads to heavy payload applications requiring significantly large moment capacity.
