Java 6 Runtime Environment

You need the Java 6 Runtime Environment for RobotLoader. You can choose between 32 and 64 bit Versions, whichever is suitable for your Operating System.
For Linux you can choose between self extracting or RPM Versions for 32 and 64bit systems. It is recommended that you use the Package Manager of your Linux Distribution if possible.

You can get newer Versions of the JRE here:

Note: Java 6 is not available for old Operating Systems like Windows 98 or Win2K without SP4. Contact us in case you still use such an old Operating System.


RobotLoader v.1.5

This Program has been developed to allow easy and fast program upload to the Microcontrollers on Caterpillar and some other robots from Global Specialties. It is written in Java and runs on Windows and Linux. You do not need to install it - you can simply extract it to a folder on your hard drive and start it from there.
If you are using Windows, you have to install the USB driver before you can use this program (see below).

WinAVR Version 201001100

WinAVR is a suite of executable, open source software development tools for the Atmel AVR Microcontrollers. It allows you to run AVR-GCC (C-Compiler) and other open source tools on Windows. It is easy to install - just follow the instructions on your screen after launching the installer. Note: There are some different Versions of WinAVR on this CD - this was done in case the newest Version causes Problems.

USB Interface Driver

This is the FTDI USB Driver for Windows (you don't need a Driver for Linux as it is already included in modern Linux Kernels). The newest CDM 2.06.02 Version is available for Win2k/XP/Vista/Win7 32 and 64 Bit. You can use the CDM_Setup to install the Driver BEFORE you attach the USB Interface for the first time. If you want to install it manually, you find the extracted drivers in the apropriate folders on the CD. The Installation is described in the manual and there are also Installation Guides in the driver folders.

Attention: Windows 7 and Vista can contain a standard Driver for the USB Interface but this one is not complete! It does not have all required Features. So you HAVE TO install the correct Driver BEFORE you attach the USB Interface for the first time. If you did not do this, you have to manually upgrade the Driver with the Windows Device Manager.

Newer Versions of the Drivers can be downloaded from our website or directly from FTDI:

avr-gcc, binutils, avr-libc and patches

This folder contains everything required to compile and install the avr-gcc, binutils and avr-libc for Linux. There are several patches that need to be applied to these packages. There is an automatic script that can do this. Of course you can also compile and install everything manually. This is described in the manual. You should read it, this is not as easy as it is with WinAVR for Windows and you need to do several things on the command line...
