![]() ![]() It actually did not need to be customised much beyond the layers of software called board support package (BSP) that let VxWorks run on space computers. One of the amazing things about VxWorks is its flexibility. How was the RTOS of Curiosity customised for this particular mission?Ī. Once it had landed safely, the instructions that tell it how to be a robotic geologist were sent up. For instance, the craft did not have instructions for ED&L until perhaps a week before it needed them. The craft is also able to upgrade software packages while in-flight. VxWorks was actually in control of the spacecraft’s flight from the minute the rocket took off. The OS controls the entire process with precision and determinism. In this case, applications included for ED&L procedure take readings from various avionics packages and trigger rockets and other devices to control the landing process. The OS allows programmers to make the computer do all the things that their applications need, fulfilling the purpose of their device. Just as a Windows or Linux operating system makes your desktop or laptop computer (or cell phone) useful to you as a device, the OS inside flight computers is what makes them a functional space robot. Wind River VxWorks RTOS serves as the OS inside flight computers on Mars rover Curiosity. How did VxWorks help the Mars rover Curiosity to tackle the so-called ‘7 minutes of terror’ in the entry, descent and landing sequence (ED&L)?Ī. We are going to see an increased need for multi-core support and virtualisation, increased need for robust fault-tolerant supervisory systems, and increased support for Open standards and systems. This, in turn, means remotely deployed systems will need more kinds of applications running on them simultaneously to achieve their objectives. As the need to return more information than raw data grows, these systems will need to do more of number crunching/application processing than had been done by ground and control systems back at the lab. Advanced robotics, telepresence and autonomous control all require enormous amount of high-powered deterministic computing. ![]() What is brewing in the RTOS field? Do you see any particular trend dominating in the near future?Ī. Its flagship product VxWorks was recently used within the Mars rover ‘Curiosity.’ Mike Deliman, senior technologist at Wind River, spoke to Ashwin Gopinath of EFY about designing real-time operating system (RTOS) for outer space and the famously complex EDL sequence It has been pioneering computing inside embedded devices since 1981, and its technology is used in more than one billion products. Wind River, a wholly owned subsidiary of Intel Corporation, is a major player in embedded and mobile software. It features the MagicMenu, the ability to bind a variable number of finger clicks, taps, swipes, pinch and other gestures to functions like Middle Click, Hold Down Both. Extend the functionality and configuration options of the Apple Magic Mouse. the zones for all gestures are now editable - added 2 new MagicMenu triggers: One Finger Middle Axis Click and Three Finger ClickĮxtend the functionality and configuration. Also featured is a real-time display of the fingers touching the surface of the mouse that you can enable to test and monitor the way the mouse sees fingers. It is also possible to add custom keyboard shortcuts and macros, or custom applications and bind them to any gesture in magicprefs. Tracking Speed adds the ability to increase the maximum mouse speed by a extra 200%. Touch Sensitivity implements a single point control for a number of factors impacting the algorithms of the taps, swipes, pinche and other gestures. It features the MagicMenu, the ability to bind a variable number of finger clicks, taps, swipes, pinch and other gestures to functions like Middle Click, Hold Down Both Mouse Buttons, Spaces, Expose, Dashboard etc. ![]()
