Robotic arm & traxster

Posted by Syed Abbas May 19, 2011

The aim of this project is to control a Robotic Arm which is mounted on to  the Traxster.  Wii Nunchuck is used to control Robotic Arm and Traxster. We are just using the two buttons and the Joystick and this data is been transfers wirelessly using the Xbee Shield between the two  Arduinos. We are using a L298N to run the DC motors of the traxster which has been made in to the PCB. we are using 9 vold battery to power the Arduino which is in the traxaster and 12 Volt battery to power the Traxster. the 12 Volt have been passed to voltage regulator to supply power to the H-bridge. 5 Volts have been given to the robotic Arm from the arduino. Servo motors of robotic arm will be mapped to 180 according to the joystick movement. The speed on the DC motors will controlled by varying PWM pins of the Arduino. The project is successfully completed. We are able to control the Traxster and Robotic Arm,  but  we may not get to the exact required position as the system is  a open loop.

Embedded software engineers only need to know one programming  language to get through life: C. Most embedded software projects are  written in C. So that leaves most other languages out of use (I insist,  for embedded programmers). I always wonder if I need to start learning a  new language, and if so, which one. With so many things to keep  learning about, I usually barely have time to read up on the latest  developments in the technologies I work with, so learning a new language  has been constantly left “for later”.


C++ seems to be a pretty obvious choice as a next programming  language, as far as I know, it’s the second most used language in  embedded systems. There are also some less obvious choices out there  like Ada or B# (yes, you read correctly).

Dynamic Security Lock

Posted by Andy_Sills May 13, 2011

for my project i produced a security locking device where a new code was generated every hour. it used a one way encryption alogithm, to scramble the time and key data producing a new password. it has a number of features including admin login to generate a new key which was saved in the EEPROM, also lockdown mode if a user had three 'wrong guesses.'' the project came complete with an iphone application with the same algorithm uploaded to the code could be revealed. the algorithm was a mixurture of bitwise and integer arithmatic,

Going into the 2011 Embedded Systems Conference Silicon Valley I was looking forward in particular to seeing and hearing more about new MCUs and ecosystem developments.


 

The show did not disappoint.


 

If there was one product to capture “best in show” honors a good argument could be made on behalf of TI’s MSP430FR57xx, a 16-bit microcontroller said to be the industry's first low power ferroelectric random access memory (FRAM) MCU. TI has been working on FRAM technology for about a decade, but this is the first time that the memory has been integrated into a microcontroller. The new MCU is said to reduce active power by up to 50 percent when executing code from FRAM,  operating at 100 µA/MHz in active mode and 3 µA in real-time clock mode.


 

What’s more, the on-chip FRAM allows data retention in all power modes, supports more than 100 trillion write cycles, and allows developers to partition data and programming memory with changes in software.


For product designers, the new technology provides the ability to deploy and monitor sensors for years at a time. TI engineers foresee it being used on many of the country's 600,000 bridges, or on other types of remote structures where safety and security is critical.

 

Microchip Technology has expanded its 8-bit Enhanced Mid-range Core product portfolio with the new, PIC16F1516/7/8/9 and PIC16F1526/7 (PIC16F15XX). MCUs. These new, general-purpose MCUs feature Microchip’s eXtreme Low Power (XLP) technology—for sleep currents down to 20 nA, and active currents less than 50 micro Amperes/MHz, according to the company—which lowers overall power consumption and extends battery life.


 

This MCU family offers 5V operation, which is important for many home appliance and automotive applications. An on-chip, 10-bit Analog-to-Digital Converter (ADC) with up to 30 channels enables more mTouch capacitive touch-sensing keys and sliders in smaller packages. Up to two each of EUSART, I2C and SPI ports enable communication with on-board peripherals. The new MCUs are available in 28-, 40-/44- and 64-pin packages.


 

Renesas Electronics America announced new support for its RL78 microcontroller family including compiler support from IAR Systems, real-time operating systems (RTOS) from Micrium and CMX Systems, and Wi-Fi (802.11n) support from Redpine Signals. IAR Systems' Embedded Workbench provides an optimized C and C++ compiler for the RL78 MCU family and supports the E1 on-chip debugger and IECube in-circuit emulator tools, both from Renesas Electronics. Additionally, the Embedded Workbench comes bundled with C-SPY real-time debugger, and the instruction simulator.

 

 

 

Micrium's compact and scalable µC/OS-II and µC/OS-III kernels have been ported to the RL78 family of processors so power-sensitive and environmentally conscious applications can further benefit from Micrium's µC/OS-II's and µC/OS-III's ability to enter the RL78 MCUs' SNOOZE and HALT modes when idling.

 

 

 

Similarly CMX Systems has ported its CMX-RTX operating system to Renesas Electronics' RL78 MCU family and Renesas and Redpine Signals have jointly developed 802.11a/b/g/n wireless-connectivity solutions to add low-power, single-stream 802.11n Wi-Fi capability to embedded systems that use Renesas Electronics' RL78 MCUs.

 

 

 

Contest Winners, Too


 

At ESC STMicroelectronics and EE Times  announced the winning design of the STM32 Design Challenge. Community members rated and voted from an original pool of nearly 200 designs submitted in the competition. Winners were chosen from ten finalists with the most imaginative and innovative solutions using the STM32 Discovery Kit, which was given away free to registered contestants.


 

Taking the title of Grand Prize Winner was Nghia Tran with Navicane, a talking navigation cane intended for use by visually impaired individuals. The goal of the design was to provide navigation information via audible messages and haptic feedback, helping users localize where they are and where they are headed, while improving overall mobility and decreasing dependency upon other resources. Included in this design were a magnetometer, accelerometer, proximity sensor, GPS, light and temperature sensors, audio codec and more. Mr. Tran was awarded $3,500 in addition to a free conference pass to attend ESC.


 

Honorable Mentions include the Delta Robot Clock by Justin Smith, a standard digital display on the end actuator of a delta robot; the eDiaper by Lakshmi Balasubramanian, an intelligent and hygienic moisture detection unit that alerts caregivers when to change a diaper; and a House Wide Audio System by David Erickson that included 8 inputs and up to 8 channels. Each Honorable Mention recipient received $1,000.


 

Freescale Semiconductor took the occasion of ESC to announce its “Make It Challenge”. Engineers enter the contest by enrolling in a hands-on workshop, where they receive a free biped robot replete with Freescale sensors and they are tasked with creating a unique mechatronics application. There is a $12,000 contest purse.


 

The Freescale Robot (FreeBot) is a 4-degree-of-freedom biped walking robot controlled by a Tower mechatronics board housing a 32-bit ColdFire microcontroller, 64k of RAM and 512k of flash. Four pulse-width-modulated RC servos work the leg mechanics for the FreeBot, with accelerometer, touch and other Freescale Xtrinsic sensors available via plug-in daughterboards.


The Make It Challenge live competition will take place at the Freescale Technology Forum, slated for June 20-23 in San Antonio.


 

Wozniak Assails U.S. Education


 

In a fireside chat format Q and A session with Brian Fuller of EE Times, Steve Wozniak, one of the original co-founders of Apple delivered the keynote at the Embedded Systems Conference (ESC) and was highly critical of the American education system, particularly math, science and engineering education, suggesting at one point that that the American public schools had outgrown their usefulness.

Wozniak, currently chief scientist at Fusion-io, described American education as stagnant, testing-obsessed and destructive of creativity. He said children in American schools, crowded into large classes, where they are pressured to complete and pass statewide and national standardized tests. “They’re not allowed different ways to think” he said adding that they become discouraged. Wozniak said his own children had attended public schools, but conceded, “I actually think home-schooling is very, very good as an alternative” and suggested that middle-class parents send their children to private schools.


 

Wozniak noted that over an eight year period during his career he spent some eight years “secretly” teaching at the middle and high schools levels
