About the QuadCrawler
We completely re-designed the QuadCrawler for 2004/2005 and made it even bigger and better. The QuadCrawler is the largest and lightest all aluminum quadruped kit available today.
The QuadCrawler inherits the same efficient and powerful leg design as it's larger cousin the QuadCrawler. This year we have also coupled a high quality Parallax PING))) distance detector for complete QuadCrawler autonomous control.
Expansion of your QuadCrawler kit doesn't stop there, we have also developed the QuadCrawler with the future in mind by creating expansion kits (The S3 tilt pan system S2 sensor stand) that can enhance and extend your robotic experience from the base QuadCrawler kit. Couple the QuadCrawler's hardware extensibility with the best and most popular micro controller package from Parallax and you have an unbeatable combination.
Key Features
At CrustCrawler, we believe that a Quadruped should have some key material and construction features to be a truly useful and robust robotic platform. Our QuadCrawler features include:
Super stiff yet light construction material
All aluminum components are precision CNC machined from incredibly strong .063 ga. 5052 aluminum sheeting.
Integrated Pem Stud Pivot Points
Pem studs are super smooth, solid aluminum spacers that are pressed into the aluminum body of the QuadCrawler with more than 300 pounds of pressure. These spacers are used as the servo pivot points for all of the QuadCrawler's legs. The combination of these spacers and the solid design and aluminum components are what gives the QuadCrawler it's overall rugged design and payload capacity.
Integrated Pem Nuts
Pem nuts are used throughout the key support points (16 in total) of the QuadCrawler. Pem nuts are nuts that are pressed into the aluminum sheeting with more than 200lbs. of pressure. Pem nuts lower the number of loose parts in our kits which makes our kits quick and easy to construct. Pem nuts also allow you to have quick and easy access to the lower deck of the QuadCrawler without removing major construction components.
 Horizontally Centered Leg Design
To ensure equal, physical, horizontal movement of all legs during the QuadCrawler's walking cycle, the legs have been physically designed to align with the horizontal leg servos.
Pass Through Leg Design
Having the ability to expand and add lots of additional electronics and sensors to your hexapod is a key component of robotic experimentation and development. The QuadCrawler's"pass-thru" leg design allows you to route and secure electronics at any point on the legs of the QuadCrawler without wire or electronic components being exposed or interfering with the operation of the  QuadCrawler.
Dual Deck Electronics Mount Design
The QuadCrawler has been designed so that you can mount the controlling electronics either on top of the upper deck or mounted inside,top of the lower deck. Also, the front and rear support brackets can swing open to allow easy access to the inside of the QuadCrawler for battery and electronics installation or removal. |
