Last week we almost completed our lego bug. I call it a bug cause it looks like one. We are currently using two touch sensors to navigate in the obstacle pool. There are two antennas surrounding the body of the robot, (Those antennas make the bot look like a bug.) which are connected to the touch sensors. As soon as the robot touches anything in the pool, the sensor is triggered such as the robot makes an opposite turn.

Since we also have a ramp to climb on we needed some torque. First we started with the wheels but it turned out that this was not enough. We decided to go with tank like tracks. But it was too slow for our needs. So I played with gear ratios to obtain a faster tankbug. I realized after testing that my ratio sucked while climbing. Well who cares?! Go back to the original track design. (Slow but steady )

Although I have to add a routine for “both sensors pressed” condition, I guess we are pretty stable for the navigation. Now we will spend some time on ball catching and dropping to the other side of the obstacle -|o /    

I`ll have some more pictures i guess this friday.
