Richard and David winch MARVIN, the rover, from the workshop floor to street level. The rover is being taken to Perry Lake ATV park to test the GPS system and the ability to drive the rover along a preset course using remote controls. |
MARVIN is down on the driving surface. The solenoid on the winch burned out as the vehicle was lowered, so it will have to be replaced or a new method devised for winch work. You can see the laser range-finder on the front of the vehicle. | |||

| On the roof of the vehicle is the 360° camera. Behind that you can see the exhaust pipe that was built for the generator. | You can see one of the emergency stop buttons (the red button on the yellow plate by the door). The team installed these in case the remote braking system fails at any point. You can also see the driver's seat used for driving the vehicle manually. Having multiple backup systems is necessary when one is "on the ice." | |||

| Hans secures the doors while Richard secures the rover to the boat trailer for the trip to the testing area. Hans had manually driven the rover onto the trailer | Hans and Eric work to get the actuators positioned exactly right. The actuators are responsible for running the vehicle remotely and need to be very finely tuned to ensure the vehicle can run at the speed desired, make turns, and keep the vehicle on the path. | |||

| This is some of the equipment on the equipment rack in the back of Marvin. Richard is plugging in the vehicle GPS (Global Positioning System) unit. You can see a little of the generator behind the equipment rack. | The vehicle GPS unit has been attached to the vehicle. We have great weather for this test. | |||

|||
| Richard begins setting up the GPS base station. | The antenna of the base station has been attached. | |||
|
|
|||
| The receiver is now attached. | Now the whole thing is attached to the computer for activation. | |||

| Richard works on the settings of the GPS unit and begins to receive data. | Click on the picture above to see a video of the rover driving under wireless joystick control. You will need Quicktime to access this file. | |||
