I'm assuming batteries and DC motor(s)?
Mark, yes it has four 12Vdc car batteries grouped to generate 24Vdc for
the drives. some of the option motors are 12Vdc(like plow lifting when installed).
The Drive motors are 24V brushed DC.
Does it use a model airplane style remote control?
Currently it has three modes it operates in.
1) Bluetooth(plum sized keyboard) for manual control, loading in a pickup, moving potting soil and things like that.
2) WiFi(on-board PC with cameras networked to Home or Office PC) for plowing snow.
3) Programmable for mowing and fall leaf collecting.
below is picture of my mom controlling it(snow plowing mode)
