Work Bench Jealousy

This is the work room of a member of the arduino forums. Wow, this is epic. The work bench is huge, and the shelf seems to have everything! Must have taken months to collect all that.

Arduino Piano

My next project for the arduino will  be a small piano like device. I'm still a little fuzzy on how to do it, but probably in 2 weeks  I'll have a prototype.

Sentinel Video

This is the video of my robot.

Robot 2.1.2

This is my fully functional robot with its new circular base. It avoids walls and obstacles like a pro!

This robot just gets better and better.  Leave your thoughts in the comments section.

I also added an LED to the robot to show when it sees an obstacle. (not shown in picture)

New Base of Robot 2

This is what I'm up to in the next improved version of the robot. I'm making the base circular.

Version 2.1.1 New Steering

Well I decided to take off the front steering servo. I did this for power consumption and because it requires the 2 driving servos to push forward so it can function. The new way of turning is to have one of the wheels move in opposite direction of its partner. This is more efficient because no time is wasted going forward and it moves around faster.

With this new concept I can create a cylindrical shaped robot... R2-D2

Power Supply Problems

Well, With my Robot I ran into a few problems. This is actually very good news.
I can now improve my robot. The new robot will feature 4 battery packs. That will make it heavy but it will also improve speed, torque, and play time!
Currently I hooked up 2 of the driving servos to their own 4.8 volt battery packs. This helped a lot, but the steering servo and sonar are still using 5 volts each out of the Arduino which is only powered by a 9 volt battery.

Things don't function that well when the power source is low. I hope to improve the chassis by adding a better look and maybe make it enclosed. This will be V2.2.

I also improved the code that the robot runs on.
