Motor Driver on the chip L293D

August 7th, 2011 by Robot Technology | No Comments | Filed in Electronics

Driver motors on the chip L293DDesigned for small wheeled robots, the driver is ideal for robotic classes Mini-bag, following the lineand the labyrinth of disciplines. The driver is based on the chip L293D. For the driver, you can connect two motors. The driver can operate in two modes: Mode A – always served drove a high level and, therefore, engines will be spinning at maximum speed mode with a ringing in the pulse-width modulation (PWM), supplied with the controller, you can change the motor speed.

L293D Motor Driver

July 18th, 2011 by Robot Technology | 1 Comment | Filed in Electronics, Robotics Articles

L293D ChipTo control the robot’s motors need a device that would have transformed the control signals of low power in the currents that are sufficient to control the motors. Such a device called the motor driver .

There are many various schemes for motor control. They differ in how capacity and element basis on which they are made. We will focus on the simplest driver motor control, performed in a completely ready for operation in the chip. This chip is called the L293D is one of the most popular chips intended for this purpose.

L293D contains just two drivers to control the motors of low power (four independent channels, combined in two pairs). It has two sets of inputs for control signals and two pairs of outputs for connecting electric motors. In addition, the L293D has two entrances to the inclusion of each of the drivers. These inputs are used to control the speed of electric motors using pulse width modulated signal (PWM).

NanoVM: Java Wirtual Machine for Atmel AVR ATmega8/ATmega832

June 15th, 2011 by Robot Technology | No Comments | Filed in Microcontroller, Programming, Software

Java programming for microcontroller chips, With the NanoVM, the microcontroller can be programmed in the popular Java language using the standard Sun JDK.
NanoWM Atmel Microcontroller Java Virtual Machine

NanoVM is a open-source implementation of the Java virtual machine. The NanoVM was initially developed to run on the Atmel AVR ATmega8 utilized in the Asuro Robot. It was ported to run on the C’t-Bot and the Nibo-robot and can easily be ported to other AVR-based systems.

The virtual machine uses almost 8 kilobytes of code memory (entire flash in case of ATmega8) and 256 bytes of RAM. Each and every user’s .class are processed by NanoVM’s Converter which transforms it into 1 bytecode file. Unique tools next send this file via serial line into device. For this operation is valuable NanoVM’s bootloader (alternatively you are able to use ISP programmer like: PonyProg) which store this content on-chip EEPROM.
