<h1>Mechanical Platform</h1> |
33 |
<p><span class="description">Powered by a robust 4WD system mated to a rocker |
34 |
suspension, the Scout can tackle indoor and outdoor terrain with ease. |
35 |
The cast urethane chassis provides a stable, wear resistant platform for the |
36 |
sensors and payload.</span></p> |

<h2>Chassis & Suspension</h2><br/> |
41 |
The Scout chassis was designed from the ground up to be robust and versatile. |
42 |
Fast 320rpm metal gearmotors propel the Scout at a brisk 180cm/s (~4mph). A rocker |
43 |
suspension allows the front and rear half of the robot to rotate independently, |
44 |
conforming to terrain and increasing the maximum payload. |
45 |
<br/><br/> |
46 |
|
47 |
Scout can carry in excess of 15 pounds, or pull (wagon) over 18 pounds on a level surface. Payload |
48 |
possibilities are wide open, from extra batteries to an intelligent, active sensor. Unloaded, Scout can |
49 |
ascend an impressive 80% grade (40deg) at nearly full speed. See the video below for a climbing demo. <br/><br/> |

53 |
<br/><br/> |
54 |
|
55 |
The chassis is cast from a hard urethane for a low-cost and high strength solution that minimizes part count. Areas |
56 |
subject to repeated wear such as the front undercarriage and rear accessory plate are coated |
57 |
in a protective diamond plate film. Each Scout can be customized with its own color scheme, adding |
58 |
"personality". |

<h2>Ease of Use</h2><br/> |
64 |
Components that need frequent access, such as the battery and processing board, are easily accessible. |
65 |
Flat flexible cables (FFC) are used between the two chassis halves, providing one step wiring for |
66 |
easy assembly/disassembly. |
67 |
<br/><br/> |
68 |
The accessory plate provides (6) threaded hardpoints for bolting down new sensors and custom devices. |
