Here's a robot video that I found interesting:
This Kilobot Robot Swarm was being shown on the Sheffield University stand at the Gadget Show Live 2013. They were being used to demonstrate possible swarm behaviours.
Here the Kilobot drones want to play follow-the-leader - however, there are three different leaders and each drone only wants to have one leader... They have been programmed to randomly move until they have only a single leader signal.
The guy demo'ing the little fellows was very helpful.
The Natural Robotics Lab was founded in 2010. It is led by Dr. Roderich Gross from the Department of Automatic Control and Systems Engineering, The University of Sheffield.
It investigates robotic systems inspired by nature and robotic models of natural systems. Particular emphasis is on the study of self-assembling robotic systems and swarm robotic systems.
The Kilobot was developed by the prestigious Harvard University and it is now produced and distributed by K-Team.
• Processor :
Each Kilobot has an onboard microcontroller (atmega 328)
32K program memory (used for both user program and bootloader)
1K EEPROM for storing calibration values and other non-volatile data.
• Communication :
Kilobots can communicate with neighbours up to 7 cm away by reflecting infrared (IR)
light off the ground surface.
• Sensing :
When receiving a message, distance to the transmitting Kilobot can be determined
using received signal strength.
The brightness of the ambient light shining on a Kilobot can be detected.
• Movement :
Each Kilobot has 2 vibration motors, which are independently controllable, allowing for
differential drive of the robot.
Each motor can be set to 255 different power levels
• Light :
Each Kilobot has a red/green/blue (RGB) LED pointed upward, and each colour has 3
levels of brightness control.
• Battery management :
A Kilobot can sense its own battery voltage.
Each Kilobot has a built-in charger, which charges the onboard battery when +6 volts is
applied to any of the legs, and GND is applied to the charging tab.
• Debug :
A serial output header is available on each robot for debugging via computer terminal.
• Dimension :
The diameter is 33 mm and the height is 34mm (including the legs)
I took these videos with a Canon 650D + zoom STM lens on Friday 5th April 2013 at The Gadget Show Live 2013 event held annually at the NEC, Birmingham.
I created this video with the YouTube Video Editor (http://www.youtube.com/editor)
