Hi All,

Finally getting my ArduRover moving (pun intended) again now that I have retired and finally resettled to Flordia. I have included a couple of pictures. One is the basic Traxxas E-Maxxs Chassis with a 1/4" thick HDPE plate attached between the body support posts. The other pictures are a mockup of the obstacle avoidance sensors and Arduino Uno processor. There will be another plate mounted 2 and 1/2" above the lower plate and will support an APM1/Oilpan, GPS, compass, 3DR 900MHz telemetry module, a GoPro HD camera (just like JLN), and assorted batteries and running lights. I plan to test the obstacle avoidance and navigation functions separately and then integrate them once they function on their own.

Regards,

TCIII

Are you copying my design? :P Cuz it works great! You can get threaded plastic posts online. I used some that came with my hexacopter kit and they work great as you can see. I like the idea of the avoidance capabilities. Have you seen the robot that has this capability on Hk in the last few days? It is Arduino!.

Hi Grips,

Your implementation of the ArduRover concept looks great! How does it run? What frequency is your video transmitted on? Also, is that an OSD on the output of the Oilpan or what? No, haven't seen the HK robot. Will check their website.

Hi Grips,

Can you provide a link to the HK robot? Nothing pops up for me on a search of their sight.

Mine is going to looks something like this, except for the front axle; ended up with a Nitro 4x4 chassis instead of an electric on the one auction I bid on. The fun part is going to be making it look like a scaled down version of my 2004 Chevy Trailblazer. 

Incase anyone is wondering where the Parallax PINGs, Arduino Uno, IR sensors, and chassis framework came from, I got them as a kit from the MINDS-i Robot Store for the unbelieveable price of $80 back in July of this year.

That indeed is an Minimosd. I use 910mhz for my Video as it has the best penetration capabilities. I use a Turnigy 9x with a 9ch reciever for control of the rover when its in this configuration. I have a set of Fatshark Goggles for FPV and headtracking.  The only issue I am having thus far is that the minimosd will not recognize the mavlink heartbeats from the apm.. odd.. So all I get is "awaiting mavlink heartbeat"  from the osd. It used to work perfectly on my hexacopter.

And to add.. your setup looks badass thus far. Have you started the programming for the avoidance? I'd look into that code on that HK robot as it may be able to be adapted.

Hi Grips,

The MINDS-i people have already written avoidance software using their PING and IR sensors. It trys to keep the rover going straight unless there is an obstacle detected either in front or off to the sides. I have modified it to take navigation input from the APM instead of trying to just go straight ahead. I will see how that works as I integrate the two systems.

I don't know what happened to my reply last night.

Where are the other two driven wheels?  I like the idea of the 3DR radio, but I'll probably just use WiFi and ROS.

Alan,

If you are referring to my Traxxas E-Maxxs, it comes stock as a 4WD chassis. Only the front wheels steer, but with the soft knobby tires, this thing sticks to asphalt like glue and can make very tight turns without 4WSteering.

Hi All,

Tower Hobbies sent me a $10 promotional credit so I decided to buy an Integy Alloy Roof Top Spot Light Set (4) LED White so I can run my ArduRover at night and see what direction it is going in the dark.

Got the upper plate cut to the same size as the lower plate and drilled matching 1/4" holes in both plates for 1/4" dia threaded rods to support the upper plate above the lower plate. Also finished mounting the MINDS-i sensors and Arduino UNO on the lower plate. Plan to determine the best placement of the APM1/Oilpan, GPS, compass, and 3DR 900MHz telemetry modules on the upper plate tomorrow and then get them mounted on the plate. I kind of like JLNs wooden AMP1 case (I have two) and his Tupperware enclosure!

I think that I will build a home-made rollbar for the upper plate to protect the modules in case of a rollover.

Hi Thomas,


I was kidding on the two extra wheels ;>)

I've currently just got a sheet of 1/4" Plexiglas on my 'bot, I'll order up parts to build a long box (might be as big as 16" x 24") to hold all my stuff. 

Alan

Alan,

I see now. You were looking for the third pair of wheels! LOL.

How about some pics? Maybe start a build log since you have a real custom rover going?

Regards,

TCIII
