[quote]So, what are you going to do next with the Rosvem? Any plans to do live video?

Yup. The software is already ready for live video. It’s now working with the webcam of my laptop, but using composite video via usb works perfectly too. Only thing left to do is buying a camera (suggestions?)
You can also see that there is, at this point, random sensor data coming back from the robot. Which is displayed as an overlay on top of the video in the software.
Next step (which I will start with now) is to hook the electronics to a perf board and start soldering
The perf board is ready. If I can arrange it, I will upload a picture today.
Via a wireless camera system. The receiver signal will be transferred through usb to my laptop.
Intelligence, yes. Mostly sensors and gps. Not sure what excactly at this point.
[quote]Wonderful! Your video has inspired me to devote more time back to my little bot. I’ve been having issues with the structure and drive mechanisms.

Need to drill some mounting holes later on.
And I need to add another print connector for powering the two amperage sensors. The motor controllers only provide 3.8V instead of 5…
And, I need to add another voltage divider. Maybe even a small voltage regulator circuit.
The hex shaft from the Tamiya gearbox slips in the Tamiya drive wheels. If there’s any resistance, then the bot stops going, despite my motors and gearbox spinning.
I bought some Pololu aluminum disks that have a set screw to lock it on to the hex shaft, but I need to find screws that fit to attach these to the wheels.
(Looks like the same setup with ROSVEM Mark 1)

Seeing your bot, has gotten me to think a bit differently about how to construct mine. I may scrap the system I have altogether and start over again.
Which is ok … since the mechanical stuff was bought cheaply so that I could focus on the FEZ part. I feel somewhat confident with that, now I can move on to a different part of the challenge.
I like your use of cordless drill motors and batteries!!
Would the DC Motor Controller board sold by TinyCLR work with those motors?
BTW - I just subscribed to your RSS feed! Looking forward to some updates

I did not have any of these problems with v1. The gear boxes were pretty stable, even when driving on carpet.

Not that will not work. The motors are way too powerful for those motor drivers. The ones I use can power up to 20a each.
A cordless drill motor will ask around 8,5-10 amps when there is no torque.
“I bought some Pololu aluminum disks that have a set screw to lock it on to the hex shaft, but I need to find screws that fit to attach these to the wheels.”
Not sure you can get these exactly at HomeDepot, but maybe your local hardware. Mcmaster-carr would have, but you probably need more stuff at pololu anyway - right?
I wish the stepper shafts they sell where keyed. That tiny set screw will head strip and not hold very well under load over time unless you have flat spot on the shaft or it is keyed.
Should I say : “as usual” ?
