Do you need legs for a custom robotics project?
CrustCrawler leg kits are an established out-of-the-box alternative to manufacturing your own robotic legs. These 3 degrees of freedom, 3 servos-leg kits are the same design found on our Nomad HDATS and Hexcrawler HDATS Robotic kits. They offer robot enthusiasts advanced design and adjustable versatility.

3DOF kits features
√  Rugged all aluminum construction
√  Adjustable fulcrum points for heavy payload capacities
√  Designed for use with a variety of digital or analog servos
√  Can be attached to your custom robot project any number of ways using our exclusive "servo hinge bracket" design
The servo hinge bracket provides easy mounting to any frame. Each servo hinge bracket has 4/40" mounting holes located on the top, side, and bottom of the bracket. Two leg assemblies can attach to each other (see pictures) or attach to any frame through the 4/40" holes. This designed flexibility is what makes our 3DOF and 2DOF legs kits adaptable to any robotic project!

Servo Configuration Purchase Options

The tables above display several leg-servo configuration options. Please download and read the construction guides for optimum leg/servo configuration performance. Do not simply pick the cheapest or the most expensive servos. Figure out what you need for your project keeping in mind any extra weight you might need to carry payloads such as batteries, electronics and added hardware.
