In the Boston Sunday Globe[1] newspaper this week, there was an article featuring the Boston Dynamics BigDog. The BigDog is a 240 lb (109 kg), 3 ft (0.9 m) long robot designed to carry loads up to 340 lbs (154 kg), run up to 4 miles/hr (6.4 km/hr), and even climb hills. Last week, Boston Dynamics announced it had landed a $32 million grant from the U.S. Pentagon’s Defense Advanced Research Projects Agency (DARPA) to develop the next generation of BigDog for use by U.S. Marines. On the front of the BigDog is a flat tube heat exchanger to keep the BigDog from overheating. Flat tube heat exchangers typically cool oil or hydraulic fluid or electronics. Apparently the BigDog has been spotted in a park just down the road in Waltham, Massachusetts! You can watch videos of the very popular BigDog on YouTube.com.
