Hex Crawler can be used as an
educational tool for Mechanical Engineering and Programming Courses. It
is an expandable walking platform built on a high quality 0.63 gauge
5052A Type II Anodized Aluminum chassis providing sleek platform for 12
servo motors and controllers.
The full kit allows you to get started with set of useful and flexible
tools including the BR848262 (the BS2-IC), Board of Education, 12
servos, and 2 Mini SSC's allowing you to customize your robot with
additional accessories. Mounting holes and slots may be used to add
custom robotics equipment.
The Hex crawler circuits are built on the Board of Education. Together
with some additional accessories, the Hex crawler robot may be
programmed to perform all sorts of neat movements. The detailed manual
gets you started with a number of complete programs. Once you have
mastered the supplied code, you can easily customize it using your own
programming creativity. We recommend checking out the manual and source
code below so you can understand the level of complexity involved with
the assembly and programming of this kit. The kit is not complete, since
you are required to supply hand tools, a 6 cell battery pack, mounting
hardware for the Mini SSC and a 9V battery (not included).

information is outlined here:
-
Audience: Advanced Robot Enthusiasts
-
Power Supply: 9V Battery, and 6 cell
battery pack (not included). Nickel Metal Hydride (Ni-MH)
batteries are best suited for the HexCrawler. These batteries range
from 1000 to 3000 series and are readily available at most hobby
shops such as Tower Hobbies. For development purposes,
Parallax and Crust Crawler use the 3000 series Ni-MH batteries. When
properly tuned, the HexCrawler can walk up to an hour of continuous
use before a recharge of a 3000 series Ni-MH battery.
-
Assembly Tools: Angled cutters, small
Phillips screwdriver, and 1/4” wrench (not included)
-
Time Required to Build and Program: 6.0
hours - The Hex Crawler's 100 page manual guides you through the
assembly process step by step and includes 8 sample source code
programs to get you off the ground.
-
Chassis Dimensions: Main body is 13"
long, 8" wide, and 6" tall. Overall dimensions with
complete legs are 13" x 14.5" (leg to leg).
-
Height: 6" standing, 4.86"
squatting
-
Ground Clearance: The Hex Crawler's legs are
fully adjustable. Each leg offers 2 fulcrum points to choose from in
the event your HexCrawler needs to carry extra heavy loads. Each leg
can also be extended for greater ground clearance (from 3" to
4.75").
-
Leg Movement: 2 degrees of freedom (vertical
and horizontal)
-
Weight: Total kit is 4.2 lbs with servos and
electronics (no battery pack)
-
Payload Capacity: 7.5 pounds
-
Chassis Material: Super strong .063 Gauge
5052 aluminum with type II anodizing for weather and scratch
resistance. Crust Crawler machines the aluminum within
1/100" tolerance values, using state of the art drill and punch
machines. During the anodizing process, the machined parts are
"bright dipped" to give them a bright sheen and then type
II anodized to the specified color. Type II anodizing indicates the
type of hard finish that is applied during the the anodizing process
to prevent scratches and weathering to the finished product. Type II
is one of the hardest non-military specification anodizing processes
that can be applied to a commercial product.
-
Object Detection: You can purchase additional
accessories and and add-on modules and connect them to the Hex Crawler.
-
Customization: Over 155 sq. inches of total
prototyping space is available on the HexCrawler body.
-
Programming Specifications: The HexCrawler
program contains 3 fully adjustable walking gaits in just one
program! All programs are completely configurable through an
easy to use interface or programmatically depending on your
application. The code is considered RF ready, just substitute the
switch with the RF package of your choice and you are now wireless!
1) Ripple forward and backward: This gate resembles
that of a bug similar to a Genghis gait
2) Tripod forward and backward: Three legs move at once
forming a tripod resulting in a very
balanced smooth stride.
3) Turning: The robot can turn in place left and right,
literally.
-
Expandability: Breadboard or through-hole Add-on
modules will connect easily to the Add-on header. Expandability is
possible with the following add-ons (not included): BR808019
(SSIR Detectors), BR809113
(Compass), RF
modules.
