I currently have both a Rogue ATR and Rogue Blue, and neither of them is quite suitable in their current form, so I am looking for some suggestions as to suitable replacement chassis.
The chassis will just be a sensor platform, and it needs to be somewhat high (about a foot or so) so that the SRF08 sensors are sufficiently up off the floor. I started with the Blue, which is a round, two wheel chassis, but it rides VERY low, and couldn’t cross the transition from carpet to floor without high-centering or something else. I got the ATR because it was a tread system, and would easily cross the boundaries. Unfortunately, it is an aggressive tread system, and with the weight of the system above it, it has VERY good traction. Too good, in fact, as it can’t do ANY skid turning without throwing a track. I have yet to make one, safe, 180 degree turn.
Therefore, I am looking for something, either tracked, or wheeled, which will be able to use the same power supply as the Rogue (I think it is about a 9V NiCad power supply) (so that I don’t have to re-configure the charging system), will have enough traction/muscle to cross a carpet threshold (many 2WD seem to be low riders, which hang up on such a boundary), and yet will be reliable enough that it can actually turn without coming apart.
Alternatively, I have thought of a few modifications of the ATR, such as smoother treads (slicks).
Any suggestions will be greatly appreciated.
