Very similar to the Robot Arm post below this is a Hexabot we built for PDC in '05.


Features:
- Tethered PC control (code written in Visual Studio)
- Mechanics are Lynxmotion parts
(http://www.trossenrobotics.com/store/c/2703-Lynxmotion.aspx) - Motors are Hitec hobby servos (HS5645 (http://www.trossenrobotics.com/store/p/3295-Hitec-Servo-HS5645.aspx) & HS645)
(http://www.trossenrobotics.com/store/p/3292-Hitec-Servo-HS645.aspx) - Controllers are Phidget USB 4 servo controllers
(http://www.trossenrobotics.com/store/p/3188-Servo-4-Motor-Controller.aspx) - 23" long, 18" wide
- 6 legs, 3 DOF each
- Input: Walking algorithms driven by computer program

I wrote a simple tri-gate walk for this crawler for the show. Later versions had different stances, turning gates, and a P&T camera head. This robot was another quick demo to show what can be built using common programming languages on a PC. Since this robot is tethered it can't go far, but who really needs a crawling robot that runs around a forest? These are research or educational robots that won't really leave the lab or classroom. Hexabot crawlers are a great way for teachers to create exciting challenges for students to work on. Everything is involved; mechanical design, creative problem solving, electronics, computer programming, physics, high level mathematics, team work, and more. I imagine a large obstacle course with the tether running to the middle. That would give about a 20 foot circular area to play in. plenty of room.


FSRs (http://www.trossenrobotics.com/2i-Force-Sensing-Resistor-Kit.aspx) can also be added to the toes of these robots to give foot pressure sensory feedback.


Accelerometers or gyros (http://www.trossenrobotics.com/store/c/3087-Accelerometers-Gyro.aspx) can be used for tilt awareness.


PS: we have 3 hexabots, including this one, that have all been lightly used for shows that are up for sale if anyone wants them. They aren't getting much use here lately and we would love to find them a good home. It's a good way to pick up a lot of expensive hardware cheap.
