Older blog entries for robotvibes (starting at number 3)

Greetings All,

I have installed 2 new features on robotvibes.com, which are "Gallery", and "Downloads". I am working on changing the layout/look of the site as well.

I added my Tech Project proposal of UltraBot 1.0 to Downloads. I am not sure where the Final Project is, but you can get the general idea from the proposal.

I am also working on fleshing out some details for the current specs of UltraMega. This will be available in the Downloads section, and a summary in the Journal.

Still tinkering with mounting the bump sensors, but the debounce circuit is built, tested and ready.

Stay tuned....

While designing the bump sensors, it deemed necessary to install the front and side panels on UltraMega, as the sensors would be mounted on the front/sides of the chassis, forming around UltraMega's body. I will be using piano wire, and some "nylon nose gear bearings" used on model airplanes to attach the bump sensors to the panels. This may still need some tinkering, to get the best response when UltraMega bumps into an object. The front/sides are now enclosed behind the panels, which are transparent lexan, that allows one to view inside the body (Nice looking!).

I have also built the debounce cct for the bump sensors, and will be connecting them to the AVR external interrupts, and testing them out.

I finally wrote up a 1 page spec of UltraMega, which should be available in Downloads. Though some updates will be made, as I get the chance. Some schematics will also be available as well.

The light sensors(Cds) will be installed next, connected to the AVR, and starting programming behavior experiments.

Note: current pics coming soon...

I designed the debouncing cct for the bump sensor in OrCad. I am also experimenting with some microswitches and piano wire for the front chassis, along with a thin strip of Lexan for the bottom of the chassis.

I have lots of documentation roughly written on paper(schematics, charts,etc.), so it needs to organized and converted to electronic form. I will also have them available here as well.

For robotvibes.com, I am planning on installing a picture gallery for the robots, and change around the look a bit.

Greetings,

I have mounted the controller power and reset switches on the 2nd level. Once the panels are mounted, the switches should be exposed just enough to toggle on/off or push reset on the controller.

I also finished up the AVR controller, and it is also installed. A quick interface test with the PonyProg yielded successful results, as the code is read/flashed. Next on the list: Bump sensors, Odometry, Light Seeking/Avoidance behaviors, and more...
