2  Community / Products and Services / Get the Veyron 24 Channel Servo Driver for free! on: June 27, 2014, 03:21:48 am
Hi all,

    We are happy to announce our product free trial going on recently, which is the newly developed Veyron 24 Channel Servo Driver. There will be 10 lucky winners to take it home. To participate, just leave us a message or drop us an email. And don’t forget to post us your review about this product afterwards!

What is Veyron Servo Driver?

    Veyron Servo Driver (24-Channel) is a multiple servo controller, especially designed for humanoid robots, spider robots, robotic arms, and many other likewise applications. It integrates wireless data transmission interface, fully compatible with DFRobot Bluetooth module, APC220 and Xbee. The controlling modes include real-time, timer, and constant speed. Veyron Servo Driver (24-Channel) is the most powerful Mirco USB servo driver with high reliability on the market.



    Veyron Servo Controller uses a high-performance, low-power STM32F103 microcontroller as its core control unit, which has a powerful, fast execution speed, high accuracy, strong I / O drive power. It supports Futaba, Hitec, Fraser and most common servos. The servo control range could be 0 ~ 180 ° (for 360 ° continuous rotation, retrofitting is needed); It has two servo control modes: single servo control, group servo control. In group control mode, the same group can be coordinated automatically with start and stop at same time. It is very useful in multi-DOF bio-mimetic robots, which requires smooth actions.

4  Community / Products and Services / Introducing the 360 Degree Laser Scanner Development Kit (RPLIDAR) on: May 07, 2014, 11:25:54 pm
Hello,

Laser scanners are commonly used in mapping, localization and obstacle avoidance in robotics. While professional scanners are usually expensive and sometimes unfriendly to developers, we've got a new 360 Degree Laser Scanner Development Kit (RPLIDAR) which provides high performance yet at a relatively affordable price.



This 360 Degree Laser Scanner Development Kit (RPLIDAR) is a low cost 360 degree 2D laser scanner (LIDAR) solution developed. The system can perform 360 degree scan within 6 meter range. The produced 2D point cloud data can be used in mapping, localization and object/environment modeling. With a scanning frequency of 5.5 hz when sampling 360 points each round, it can be configured up to 10 hz maximum. It works excellent in all kinds of indoor environment and outdoor environment without sunlight.



By using RPLIDAR, developers working on robot navigation system or indoor mapping system are able to shorten the development cycle and save lots of money. After purchase, you will also get datasheet and SDK for RPLIDAR to facility your development. A reference design of simultaneous localization and mapping (SLAM) solution for indoor robot based on RPLIDAR will be showed in the coming Maker Faire Bay Area, 2014. The reference design can sketch out a plan for the unknown environment and achieve indoor positioning with mm-level accuracy. In addition, it contains the feature of destination path searching, navigation, obstacle avoidance and so on. Also, RPLIDAR can be integrated to ROS which is widely used in many researches and fun projects.

11  Development / Other Hardware Development / Re: which is best Wifi shield for arduino? on: March 16, 2013, 11:38:47 am
Try this  http://www.dfrobot.com/index.php?route=product/product&filter_name=wifi&product_id=548#.UUSf0VvN_kw

It uses a mature WizFi210 chip. It provides the bridging from TTL serial port communication to IEEE802.11b/g/n wireless communication. So any device with TTL serial ports can easily be connected with this WIFI module and controlled and managed remotely through a wireless network. Different kinds of communication protocols and encryption algorithms are integrated with the module. The Arduino architecture enables you to easily integrate this module into any Arduino based project.

It is  not the first small Leonardo - my Leonardino (little leonardo) was out quite a while ago - and I brought out 25 IO lines,


All right. You are the first guy smiley-twist smiley-twist.   Your work looks nice too.   
15  Community / Products and Services / Announce the world first Nano sized Leonardo -Dreamer Nano on: October 25, 2012, 12:52:20 am
DFRobot just released the first Nano sized Leonardo- Dreamer Nano

The Dreamer Nano V4.0 is a surface mount breadboard embedded version of the ATMEGA 32U4 with integrated Micro USB. It has everything that Leonardo has (electrically).Physically, it is just missing power jack to save space.
 
Using the ATmega32U4 as its sole microcontroller allows it to be cheaper and simpler. Also, because the 32U4 is handling the USB directly, code libraries are available which allow the board to emulate a computer keyboard, mouse, and more using the USB-HID protocol!
 
The Dreamer Nano v4.0 is compatible with most Nano shield in the market. It's suitable for projects that require a compact size controller system.

Specification:
  • Input Voltage: 6.5-12v (VIN) / 5v (Micro USB)
  • ATmega32u4 Microcontroller
  • 20 Digital I/O Pins
  • 7 PWM Channels
  • 12 ADCs
  • 16MHz Clock Speed
  • 32 KB Flash Memory
  • Compatible with most of Nano shield
  • Size: 45x20x20mm
