ROBOT SCOOTER
My initial calculations showed that it would be feasible to move a 150 lbs person 6 feet in 1.5 seconds. Only looking at the required power, ignoring any losses due to friction, and assuming the motors are running at max power, it would take about 3 CIMs, the maximum that could realistically fit in the desired dimensions.

For my project, I am designing a motorized scooter. The scooter should be approximately 20” long by 5” wide by 5” tall. It will be made from a combination of COTS (Consumer Off The Shelf) parts, custom cut and milled parts, and custom waterjet-cut sheet metal. The scooter will be powered by a 17Ah 12 Volt battery, powering three CIMs (Chiaphua Industrial Motors). The motors will run a custom-designed gearbox, which will power the scooter’s rear wheel. The scooter will be controlled by an Arduino microcontroller, which is governed by a hand switch on the handle and governs three Spark brushed DC motor controllers, which control the three CIMs.
Here are some sources I used to find the specs that I used for my calculations:
