Little Line and Ledge Bot
Little Line and Ledge Bot
***UPDATE 8.3.12***
Added video of desktop/ bump and turn routine
(Top Video)
Well, its about time!
I finally got around to designing a good, solid line and ledge bot. This little guy is set up for lines, mazes and ledges (deskbot) with its 5-sensor bar up front. Three sensors are mounted together in the center, spaced to match the width of electrical tape. Two more sensors are mounted to the far outsides. These two extra sensors are slightly wider than the wheels and thus, can detect an edge with plenty of time to stop or change direction. They are also super handy when used as a maze-solving robot --the 2 outside sensors are just what you need when following courses with 90 degree turns.
Disclaimer:
On top of all this line-follow goodness, we add a Dagu Micro Magian Board:
- Atmega168 (Speaking Arduino)
- On-board USB
- Sweet motor driver (with brakes)
- 3 axis accelerometer (not only a "tilt" sensor, but can also detect impacts as well --Create a bump-and-turn bot without the bump switches!
- On board IR sensor --Control this bot via IR with any Sony or Universal TV remote control
There is even a cut-out for a micro servo added to the chassis if you ever want to add a "head" or pan and tilt kit to your bot.
Included in the Kit:
- Laser cut acrylic chassis
- All hardware needed for assembly
- 120:1 geared motors
- 60mm wheels
- 4 AAA battery holder
- Line Follow sensor bar
- All wires, jumpers and doo-dads needed for assembly
- Micro Magician board
**Available as no-solder kit!
Disclaimer:
This robot can be used as a "ledge finder" and/or "deskbot". This means, of course, that this robot will be around ledges. It is a true possibility that this robot may miss said ledge and take a tumble to the floor. Good code and observation will prevent this from happening.
It is your responsibility to protect this robot from falling. Code well, test your stuff. Do not trust code from RBS or others to "just work" --You must do your testing and homework before you let this guy roam your desktop.
If for some reason you do break something, please email me. I am a very nice guy and will probably take pity on you. I will be sure you get replacement parts and I won't cost you an arm and leg. Promise.
