Hello,
Well here is the code, the modifications are only on the maze-solve.c class, the maze shown on the video has 71 steps.
the main Idea was to record the turns and the intersection type, I wrote some comments about it on the code, then when we start the robot from any point it will run for some steps to decide its location, then we simplify the rest of the path to the end, then the robot follows the simplified path!

The Code:
Code: Select all Expand

Maze solver from any location

Postby moatasa » Tue Jan 15, 2013 12:14 pm

Well, I have been working on some improvements on the code.
The improvements include:
1- Increasing the motors speed, when tracking from 60 to 90, when turning from 80 to 120.
2- Finding the location in fewer steps.
3- Solving bigger maze size (up to 400 steps).

I tried the robot on a bigger maze (193 steps), check the image below:

Finally here is a video comparing the robot performance before and after the improvements:

Enjoy................. :-)

This video, entitled Human Use of Human Beings, was originally posted in another thread by kom75. It is a project by Robin Meier and Ali Momeni that features lots of 3pi robots:

Project Paw Print

Postby Geoff » Sun May 05, 2013 4:02 pm

Well, we've done it again!

Tabletop Robotics has created a simple global vision system called Project Paw Print, which coordinates the behaviour of multiple 3pi robots, and instructs them to form a stationary formation. Robots can be added or removed at any time, and the remaining ones will automatically balance the formation. Check out the video demo here.

The Tabletop Robotics website has undergone a few changes, too. In addition to a new look, we've also added a Challenges section that contains a few interesting projects for ambitious fans of the 3pi.

Thanks,
Geoff

Hi all,

The source code for the global vision system, Paw Print, is now available upon request on my website.

The documentation for this project is somewhat lacking due to my busy schedule, but the system is simple enough to figure out, and source code comments abound.

Thanks,
Geoff
