The cause was lung cancer, his son Vanja said.

For 26 years, Mr. Douglas was the executive director of the California Coastal Commission , the powerful state agency that he helped create with a mandate to keep the coast open to the public — and one that set a high standard for its counterparts in other states.

He brought a profound passion for the sea to the task.

Mr. Douglas was a boy when he, his mother and sister boarded a ship to cross the English Channel while emigrating from Germany after World War II , eventually coming to the United States. The roiling currents and tides entranced him, he once said, creating "an intangible, unbreakable, lifelong bond."

It became his mission to ensure that all Californians could swim, surf, fish or just see the sea along the 1.5 million acres of the state's 1,100 miles of coastline — to the consternation of many commercial interests and property owners.

Mr. Douglas was the executive director of the commission from 1985 until November, when he stepped down because of his declining health.

Bearded and usually wearing Birkenstock sandals, a bolo tie and hiking pants, he was known to sometimes pull his biodiesel car to the side of a highway and stand in front of bulldozers operating without a permit.

"Few, if any, conservation leaders have had a greater impact on protecting California's stunning coastal resources, and all Americans owe him a great debt of gratitude," Kerry O'Toole, president of the American Land Conservancy, said when Mr. Douglas retired.

Mr. Douglas was a young lawyer working for a state assemblyman in the early 1970s when he was assigned to draft legislation to protect the coastline. In that capacity, he was the principal writer of Proposition 20 , the 1972 referendum that established the commission.

He helped write the Coastal Act of 1976, which gave the commission permanent status as a quasi-judicial agency with jurisdiction that often surpasses that of city officials and the state authorities. The commission's mandate includes limiting coastal construction, ensuring public access to beaches and advocating for regulation of offshore drilling .

During Mr. Douglas's tenure, the agency helped create thousands of acres of parklands and public trails. The agency also secured more than 1,300 easements for paths to the shore through private property, and its efforts led to the preservation of much of Highway 1 as a two-lane road weaving through farmland, cliffs and dunes.

In one of its most prominent decisions, the commission denied a 1998 plan by heirs to William Randolph Hearst, the famed newspaper publisher, to build a 650-room resort and golf course on the vast Hearst estate near the shore in San Simeon. It would have obstructed views and public access and intruded on sensitive wildlife habitats, the commission concluded.

Mr. Douglas provoked considerable opposition, particularly from the Pacific Legal Foundation , which has sued the commission in dozens of cases. Paul Beard, head of the foundation's legal team, said: "Under Douglas's leadership, the commission became the rogue agency that it is, running roughshod over people's rights, destroying economic opportunity and, ironically, making it unaffordable for all but the wealthiest to buy land in California's coastal zone."

But for Annie Notthoff, the California advocacy director for the Natural Resources Defense Council, a national organization, he was a groundbreaker.

"California set the standard for protecting the coast, and that has expanded to almost every other coastal state in the country," she said. "So if you look out to sea anywhere in the country, California and Peter Douglas have had a major impact."

Not enough of an impact, according to Mr. Douglas. "The coast," he told The Los Angeles Times in 2001, "is never saved. It's always being saved."

Born Peter Michael Ehlers in Berlin on Aug. 22, 1942, (he and his sister changed their last name upon becoming American citizens), Mr. Douglas and his mother, Maria, and sister, Christiane, joined relatives in Los Angeles after arriving in the United States in 1950.

Besides his son and his sister, Mr. Douglas (who lived in Larkspur, Calif., and had a home by a river near the Oregon border) is survived by another son, Sascha; and two grandchildren. His marriage to the former Rotraut Schmidt ended in divorce.

He was "the world's best bureaucratic street fighter," Steve Blank, a member of the commission, told The New York Times in 2010.

"Once he's gone, this commission will implode in the blink of an eye," Mr. Blank said, "and all we'll be talking about is the color of the concrete used to pave over what's left of the coast."

Seeking Robots to Go Where First Responders Cant

In the event of another disaster at a nuclear power plant, the first responders may not be humans but robots. They may not even look humanoid.

DARPA

RESCUE ME A defense research challenge envisions robots, humanoid or otherwise, that can work in disaster zones.

The Pentagon's research and development agency is to announce a competition on Tuesday to design specialized robots that can work in disaster zones while operating common tools and vehicles. And while such tasks may well inspire humanoid designs, roboticists say they may also lead to the robotic equivalent of the Minotaur — a hybrid creature that might have multiple arms and not just legs but treads. Rumors of the challenge have already set professional and amateur robot builders buzzing with speculation about possible designs and alliances. Aaron Edsinger, a founder of Meka Robotics in San Francisco, said he was speaking with fellow roboticists around the country and was considering a wide array of possible inspirations.

"Analogs to animals such as spiders, monkeys, bears, kangaroos and goats are useful inspiration when considering parts of the challenge," he said.

In the Tuesday announcement, the Defense Advanced Research and Planning Agency, or Darpa , lists eight likely tasks the robot will need to perform — among them driving a vehicle to a simulated disaster site, moving across rubble, removing rubble from an entryway, climbing a ladder, using a tool to break through a concrete wall, finding and closing a valve on a leaking pipe, and replacing a component like a cooling pump.

Mr. Edsinger said the challenge would be not in completing any one of the tasks but rather in integrating them into a single mission. "I feel we have already have systems that can achieve each individual task in the challenge," he said.

The idea for the competition came from the Fukushima nuclear disaster in Japan a year ago, said Gill Pratt, a program manager in Darpa's defense sciences office. "During the first 24 hours," he added, "there were things that should have been done but were not done because it was too dangerous for people to do them."

The agency has not yet announced how much it intends to spend on the program or the size of the prize. It is calling the program a "robotics challenge," which is distinguished from a series of "grand challenge" events it held in 2004, 2005 and 2007, with $1 million and $2 million prizes for a contest to design autonomous vehicles to drive in desert and urban settings.

Corporate and university teams will compete to enter the robots in contests in 2013 and 2015. The robots will not need to be completely autonomous, but rather will be "supervised" by human operators, much as ground-based pilots now fly military drones.

The competition underscores the rapid progress being made in autonomous systems in military, manufacturing and home applications. Robotics researchers have said that these advances are largely a result of the falling cost of all kinds of sensors, as well as developments in perception technologies that make it possible for robots to move in unplanned environments.

A number of ambitious humanoid robots have already been designed by industrial researchers. The Honda Asimo was unveiled in 2000 and by 2005 could operate for a full hour on batteries. Last year it demonstrated the ability to run as fast as six miles an hour.

Darpa officials said they were hoping for international participation in the robot competition. Indeed, the challenge echoes a proposal made in November by Hirochika Inoue, the father of humanoid robot development in Japan.

Despite Japan's significant investment in robotics, he noted that the country did not have any robots capable of completely replacing humans at the time of the Fukushima disaster.

"Many people wanted to do it by robots," he said in an e-mail, "but we had not prepared."

In the United States, both General Motors and Boston Dynamics, a small research lab financed by the military, have developed humanoid robots. G.M.'s Robonaut 2 is now on the International Space Station, where it is being tested as an astronaut's assistant. Boston Dynamics, which has attracted attention for a transport robot called BigDog and more recently for a four-legged running robot called Cheetah , has a humanoid robot called Atlas.

In its announcement, Darpa says it will distribute a test hardware platform with legs, torso, arms and head to assist some of the teams in their development efforts. Several robot researchers said a version of the Boston Dynamics Atlas was a likely candidate for this role, but Mr. Pratt said his agency would also provide a software simulator to allow the widest possible participation in the challenge.

"We're opening the aperture as wide as we can," he said.
