It's been sometime but I owe it to the forums to say thanks for the help that you all provided with the controls of the robot we did for our senior design project.
Best to watch the video

A Victim Evacuation Robotic Vehicle was designed. The purpose of this vehicle is to load and transport injured persons out of dangerous situations. The vehicle allows Emergency Medical Service personnel to conduct safer, more efficient rescue operations in a variety of different conditions. The VERV is operated from a safe distance using a wireless controller. On board cameras provide a first person view for the operator to help control and steer the VERV system to the desired location of the patient. The vehicle employs modular components such as protective shielding, removable spine-board, and Victim Retrieval System that will provide maximum versatility for any rescue situation in which risk to Emergency Medical Services (EMS) personnel should be avoided. The Victim Retrieval System (VRS) will maneuver down the inclined ramp to take hold of the injured person by, grasping the person under the arms the VRS will then pull the victim into the VERV for transport.
The full system fits in the back of a standard pickup truck to provide easy transportability. VERV has the capability to creep along at less than one mph over uneven terrain as well as sprint at 10 mph. Two 2.7 HP motors provide the needed torque to accelerate up to full speed 5 ft/sec2. The VERV runs on rechargeable batteries and have a total runtime of approximately 30-60 minutes using sealed lead acid batteries. This provides a wide range of functionality ranging from harsh terrain to city pavement. An active 6-wheel independent suspension with all wheel electric drive will be used to safely transport a patient weighing up to 350 lb and up to 6.5 feet tall.
