Yes you are correct, it is based off of 148 modules from this year. The original design had the switching transmissions within the wheel modules but due to difficulties with mantaince and access the design was changed to allow the switching transmission to be completely independent of the modules. The drive is a 4 wheel traction on the outside and then 4 trick omni's on the insides of the modules. Then a chain is linked from the inner transmission to the shaft that the traction wheel is attached to. The switching transmissions drop right out of the bottom for easy exchange. Besides that the gear ratios are rather extreme, the low gear to traction is 1:40 and then omnis are 1:20 and the high gear for traction is 1:8 and the high for omni is 1:4. These should faciaity major pushing power. Any comments would be appreciated. Perhaps someone has already created such a drivetrain in which case I apoligize for that but I did not see any other similiar drivetrains besides 148 as the base.
