Ran across this link at DVXuser…it’s a hybrid tool called The CamTransporter.

It’s a Segway-type transporter with the upper portion chopped off and knee braces installed. It allows a Steadicam operator to smoothly ride at speeds up to 13mph, and to steer and control the whole thing hands-free with only slight body movements. They claim the CamTransporter will travel either 9 or 21 miles on a single LION battery charge, depending on the model you choose.

The website has some videos of the device and operator in action, as well as a photo gallery that includes a shot of the Father of the Steadicam, Garrett Brown himself.

The CamTransporter can be rented or purchased, however the website lists no prices.
