<div>Hello <font size="2">Kumar cc DPRG list<br>
</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">Nice to meet you at the Donkey Car meeting in Plano at Improving Wednesday.</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">If you go to dprg.org website you will find mailing list archives under Historical tab.</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">Thanks for your link to indoor positioning system. I see they use ultrasonic beacons, interesting.</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">The tracking system I mentioned uses VIVE VR system. <br>
</font></div>
<div><font size="2">In this case the robot would need to operate in the envelope covered by the line laser sweeping beacons.</font></div>
<div><font size="2">The system is about $500 to including VR headset, two beacons and two hand controllers. A limitation of the system is the robot would need to be visible to the beacons, e.g. operating on the floor of a given room. It might be possible to purchase a single beacon or two for something like $135 each, and use it with ones own hardware OR use a pre-existing hand controller with the complete system OR optional $100 tracker which is smaller than a hand controller. <br>
</font></div>
<div><font size="2"><br>
</font></div>

</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">I have played with the VIVE system a bit and used it with Processing environment to render 3D scenes for the VR headset. In doing so, also have access to hand controller position data, but have not placed a controller on a robot or done any testing of accuracy of the system, but I would think the information is out there on the net.<br>
</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">One neat feature of the VIVE trackers/hand-controllers and headset is the position and orientation of the sensor is available. Also I should mention that each device includes multiple beacon sensors to make the system more robust.</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">Also, thanks on the simulator link. I will have to look at that. My Processing line following simulations do not include physics. There is some support for 3D physics in Processing.</font></div>
<div><font size="2"><br>
</font></div>
<div><font size="2">Thanks for link on GoPiGo also. Like my stepper robot platform it has the advantage of being able to operate in a small environment and moving much more slowly than RC car. I see robot has encoders, good. For more accurate turning, very narrow contact surface would be more desirable - of course just depends on what you are trying to do. <br>

<div dir="ltr">It was great to be at the meetup yesterday and get to see that there are so many people engaged in this in our area.

<div>Ron - Thanks for explaining many of the things you had worked on.</div>
<div><br clear="none"></div>
<div>At this point of time, </div>
<div>- I have a GoPiGo robot car that is functional</div>
<div>- I am interested to get Donkey car software running on this</div>
<div><br clear="none"></div>
<div>Are there archives of the DPRG mailing list that can be viewed?</div>
<div>Carl - The donkey car slack group seems very active.</div>
<div><br clear="none"></div>
<div>One robotic simulation software V-Rep (Free) that I came across a few months ago seems very rich for robotics.</div>
<div><br clear="none"></div>
<div>It does have a learning curve, but thought it may be of interest to this group.</div>
<div>Examples of what can be accomplished can be seen here <a rel="noopener noreferrer" shape="rect" target="_blank" href="http://www.coppeliarobotics.com/videos.html">http://www.coppeliarobotics.com/videos.html</a></div>

<div>Ron - This is a link to the indoor GPS with +/- 2 cm that I was talking about</div>
