Inspired by John Arne's post, I got a Redcat Rockslide, which is totally cool and a great robotics platform. As you can see, it's really easy to add a mounting platform for electronics (that's APM with GPS and Xbee mounted above) and there's LOADS of room. You could even have it carry a laptop if you wanted. BTW, that's the 1/8 size Redcat shown above, which is $236. I think the 1/10 size Redcat would probably be just as good for most uses, and it's just $159. [Update: the 1:10 isn't big enough. See this comparison]

I've registered the ArduRover name, and am now just looking for the best starting point to modify the APM code for ground rovers. Since James Goppert is part of the APM dev team, we'll probably start with his rover code, which you can see at work here. But if others have code or sensor additions to the basic APM set that would be good to add to a rover, this is the place to discuss and share.

 

Ideally, we'll get this done in time for the Sparkfun AVC contest, on the hope that APM can have a decent chance of placing in all of the categories--ground, plane and quad. Which would be awesome.

That's a little too much ;-) Maybe something in between...

Who said flying car, and why can't I seem to either embed or link video at the moment!!

Gary, use Vimeo's "old embed code"

Thanks Chris, one day I will get the hang of this interweb and maybe reading as well! Keep watching, it does fly.

thats awesome!!

 

a hybrid where you control the wheel steering and yaw of the copter with the left stick left/right and with the right stick you control the cars accelerator/brake and the copter front/back/sideways. left stick front/back stays for copter up/down. would be great!

I'm trying to get a better idea of scale. How long is it overall? Do you think it could climb stairs? And I can't find anyone who sells them in the UK :-(

Chris: I am using a 3S lipo on mine. Not been a problem so far, except for the noisy fan.

Mounting plates, sonar brackets etc will be made with cnc routers and laser cut. If people have few other good frame candidates on their mind. We could acquire few of them and make different mounting plates for those. 

 

Both redcat frames will be supported at least.

 

@Johan, that frame is a beauty too ..

I just spent over an hour exploring my neighborhood. It is fascinating to see everything anew from a low to the ground perspective. Discovering nooks and corners I never bothered having a proper look at before.

 

The trip ended with a proper roll over with three complete turns breaking the UHF pcb antenna mount. My bad, the hill did not look that steep from the camera wide angle. But it shows that we need to look into how to best mount and protect the equipment. Some kind of flexible spring mount for the antennas etc.

Johann: The low geared crawler setup draws almost nothing. Less then 200w at full throttle and much, much less at cruising/exploring speed. I power the entire crawler system using a single 3S 5000mah lipo and would estimate at least 2h of operation with room to spare.
