Here are three blog posts I wrote on the University of Edinburgh Insect Robotics Group blog that describe in detail how I made RoboAnt.
The first one – Build your own Android Robot, walks you through connecting the hardware parts.
Then, follow the second post – Remote Control, to achieve what the video above shows.
Finally, Autonomous looks at an insect inspired algorithm for autonomous navigation implemented on top the RoboAnt platform.
Let me know what you think and happy hacking!
