This is the second stage of scorch. I have added sonar and another IR ranger. This robot is fast. It uses the IR on each side to perform wall hugging behaviors. the sonar is used as speed control. The IR on the servo previously, wasnt fast enough to react in the time scorch needed. basically, scorch was too fast for this setup. the sonar now lets scorch know how fast it can go. If it doesnt sense anything for 35 feet it can go top speed, if its in my living room, scorch moves slower. this robot has turned out better than i ever expected. I dont know if there will be more to do to scorch, but it will probably get an analog devices accelorometer for collision and tilt detection in the future. so far total time to build has been about 4 months and cost is around 100 dollars.
