The image in the original post is the A4WD1. It’s replacing the 4WD1,2 and 3. We may make an articulating version (4WD2) as well. Because it has 4 wheels it can’t be a 6WD prototype.
No I’m sorry, I haven’t. I’m still putting everything together needed to get this new rover design on the website. I’m waiting on one last thing on Sep. 9th, then everything will be in place to release the 4wd version soon thereafter. Then I will finally be able to work on 6wd versions.
Sigh… I was off one day. I just received the parts this morning… It’s going to be a little longer. We got a great deal of work done on it on Friday.
The main kits will use a new motor. 12vdc, strong, fast, and has a built in encoder. The raw chassis parts will also be available for use with almost any of our gear head motors.
I had a question about the GHM-15 (I’m assuming that’s what the new 4WD will use) but when the spec says 12 ‘pulses’ does that mean 12 pulses on each channel or 12 full cycles when you consider both channels, or 12 state changes… or… Do you have a spec for the encoder by any chance? Just looking for some clarification…
I do like the sound of 12 pulses (however they are measured) when you toss in the 30:1 reduction… comes out nice and even The reason I ask about the specific wave form is that the AVR board I am using only has two interrupt pins left for quadrature (tons of GPIO so sampling B channel on the rising edge of A isn’t a problem), and I need enough resolution to do PI speed control for each side… And only using one interrupt cuts your resolution by half…
