KILO - Holonomic Drive
This design is based on KILO by Rod Gillies. KILO operates on a holonomic drive system. In this setup, robots can maintain orientation while being able to move freely in any direction. For that, omniwheels (wheels that allow for omnidirectional movement) are needed. The wheels used here aren't omniwheels but can suffice to give omnidirectional movement. They don't necessarily work well as they create friction and thus cause KILO to not travel exactly straight. I've built it with sensors to provide obstacle avoidance: An ultrasonic sensor, A HiTechnic EOPD sensor, and what I had left: A light sensor. (This system is also well known as a Killough Robot Platform) Information about holonomic drive can be found in detail at: http://technicbricks.blogspot.com/2008/08/going-to-all-places-in-all-directions_29.html Along with this article that includes mathematical equations and provides information about other unique drive systems: http://www.firstroboticscanada.org/site/files/workshops/omnidirectional.pdf |
