Software / Occupancy Mapping
« Last post by Srikar B on May 24, 2017, 03:34:28 AM »
Here I have done occupancy mapping for my cells[12*12] (attached link)

And now When my robot is in front of the cell that has already visited, which is updated in the map It should take right without visiting the same cell. how is this possible? [from picture: the position of 0 is my robot's position in the first image attaches, It moves from down to up and when it finds an obstacle it produces 1 and takes right]

Any suggestions?

Mechanics and Construction / Dagu Wild Thumper 6wd Project
« Last post by qqwea1223 on May 17, 2017, 06:11:42 PM »
Hello everybody,

I'm the new member in this forum. I join here to look for a help in my project. My professor gave me a project that using flysky transmitter to control Dagu Wild Thumper 6WD (specific detail here www.pololu.com/product/1560). Honestly, I have no experience in this field and do not know what I have to do. I already have a flysky transmitter, a Dagu wild thumper 6WD, a arduino uno, a raspberry Pi. I would be glad if you can mentor me step by step in this project. If you don't have much time, please at least give me a list what I have to do and what addition devices I have to have?

I'm just a newbie here. Therefore, If my post has any mistake, please let me know.

Thank you so much. I'm looking forward to hearing from you.

Hey Macdad, exactly the same situation here with the MB7092; silicone works in air, but no dice underwater.  I know it has been a while, but have you overcome this challenge?  How did you do it?  I think there is a lot of people interested in underwater ranging who would benefit.

[update 5/16/17]

MB7092 contains active filtering and will show last position if it cannot get 3 consecutive readings within 1 cm.  I think it may be tossing out the requested readings.  Ordered an MB7060 compact and will let everyone know how that works.

[update 5/18/17]
MB7067 (compact version with no horn) works with my test water column.
