Gizmodo posted an interesting article about quad-rotor robots that grasp objects and work together. There is a lot of ingenuity that comes into this because it is rather tough to make sure that the robot is flying straight. This becomes a bigger hassle when you want more robots to work together to complete the task.
Within my research, I started to think about what if two robots could communicate; let the other know of how it is about to move. The other thing I am trying to build is a robot that has two brains. The two micro controllers communicate with each other using the Sun Spot’s radio transmitter. One Spot is connected to a sensory system that is attached at various points around the robot and will decide how it will operate. The sensing spot then would send a signal to another Spot that is connected to the motors and operate them according to the sensing Spot. I had trouble getting the parts to put all of this together until now, so hopefully I can build a good system within the next few weeks. I will post more about DC motor control and the Sun Spot
