AVR GCC Toolchain – Ubuntu

I used to following steps to setup a working AVR toolchain on my fresh Ubuntu 14.04.1 install:

1. Install the toochain programs

sudo apt-get install gcc-avr binutils-avr gdb-avr avr-libc avrdude

2. Add udev rule for Atmel AVR ISPs.

gksudo gedit /etc/udev/rules.d/60-avrisp.rules

3. Add this text to file and save

ATTR{idVendor}=="03eb", ATTR{idProduct}=="2103", GROUP="dialout", MODE="0666" 
ATTR{idVendor}=="03eb", ATTR{idProduct}=="2104", GROUP="dialout", MODE="0666" 
# Dragon
ATTR{idVendor}=="03eb", ATTR{idProduct}=="2107", GROUP="dialout", MODE="0666"
# USBTiny
ATTR{idVendor}=="1781", ATTR{idProduct}=="0c9f", GROUP="dialout", MODE="0666"

4. Restart udev.

sudo reload udev

5. Add user to dialout group.

sudo usermod -a -G dialout YOURUSERNAME

6. Restart your computer.

7. Test.

avrdude -p atmega644p -c avrispmkII -P usb -b 115200

OKQ1: Walking

After spending most of my vacation enjoying myself I managed to get OKQ1 walking today.

This is by no means final or optimized. It was really just a quick hack to try walking for the first time. You can see the program halt twice… not sure what exactly caused that yet.

The ghetto controller you see in the video is made out of three axis joysticks, a atmega168 breakout board, an xbee and a small lipo all stuffed into a USPS mailing box.

OKQ1: Assembled, Programmed And Moving

I was able to spend some time over the weekend to travel to robotics Mecca (Trossen Robotics HQ). While visiting I made some significant progress on the assembly of OKQ1. I was even able to set all the MX-64T servo IDs and buadrates.

Here is a short video the TR crew took of OKQ1’s first power up and software run:

OKQ1: Assembly

Parts for my quad, OKQ1, have started to show up in the mail and I have been busy assembling them.

One leg assembled and sitting next to the AX-12 prototype chassis for comparison:

All four legs assembled:

OKQ1: Target Tracking And Auto Targeting

I have been working on ideas for simple target tracking or auto targeting systems to use in Mech Warfare that do not require an on board computer running vision software. I believe that I have found a suitable solution and this week I have made some significant progress prototyping it.

Below you can watch two videos of the prototype tracking/targeting system.

Unlike all my other Mech Warfare work I will not be releasing the details on this system until after the 2013 Robogames event.
