As “Artificial Intelligence” Advances, Robots Learn Via Trial and Error
By Sarah Yang, UC Berkeley News
UC Berkeley researchers have developed algorithms that enable robots to learn motor tasks through trial and error using a process that more closely approximates the way humans learn, marking a major milestone in the field of artificial intelligence.
They demonstrated their technique, a type of reinforcement learning, by having a robot complete various tasks — putting a clothes hanger on a rack, assembling a toy plane, screwing a cap on a water bottle, and more — without pre-programmed details about its surroundings.
“What we’re reporting on here is a new approach to empowering a robot to learn,” said Professor Pieter Abbeel of UC Berkeley’s Department of Electrical Engineering and Computer Sciences. “The key is that when a robot is faced with something new, we won’t have to reprogram it. The exact same software, which encodes how the robot can learn, was used to allow the robot to learn all the different tasks we gave it.”
The latest developments were presented on Thursday in Seattle at the International Conference on Robotics and Automation (ICRA). Abbeel is leading the project with fellow UC Berkeley faculty member Trevor Darrell, director of the Berkeley Vision and Learning Center. Other members of the research team are postdoctoral researcher Sergey Levine and Ph.D. student Chelsea Finn.
The work is part of a new People and Robots Initiative at UC’s Center for Information Technology Research in the Interest of Society (CITRIS). The new multi-campus, multidisciplinary research initiative seeks to keep the dizzying advances in artificial intelligence, robotics and automation aligned to human needs.
“Most robotic applications are in controlled environments where objects are in predictable positions,” said Darrell. “The challenge of putting robots into real-life settings, like homes or offices, is that those environments are constantly changing. The robot must be able to perceive and adapt to its surroundings.”
Conventional, but impractical, approaches to helping a robot make its way through a 3D world include pre-programming it to handle the vast range of possible scenarios or creating simulated environments within which the robot operates.
Instead, the UC Berkeley researchers turned to a new branch of artificial intelligence known as deep learning, which is loosely inspired by the neural circuitry of the human brain when it perceives and interacts with the world.
“For all our versatility, humans are not born with a repertoire of behaviors that can be deployed like a Swiss army knife, and we do not need to be programmed,” said Levine. “Instead, we learn new skills over the course of our life from experience and from other humans. This learning process is so deeply rooted in our nervous system, that we cannot even communicate to another person precisely how the resulting skill should be executed. We can at best hope to offer pointers and guidance as they learn it on their own.”
In the experiments, the UC Berkeley researchers worked with a Willow Garage Personal Robot 2 (PR2), which they nicknamed BRETT, or Berkeley Robot for the Elimination of Tedious Tasks.
They presented BRETT with a series of motor tasks, such as placing blocks into matching openings or stacking Lego blocks. The algorithm controlling BRETT’s learning included a reward function that provided a score based upon how well the robot was doing with the task.
Abbeel says the field will likely see significant improvements as the ability to process vast amounts of data improves.
“With more data, you can start learning more complex things,” he said. “We still have a long way to go before our robots can learn to clean a house or sort laundry, but our initial results indicate that these kinds of deep learning techniques can have a transformative effect in terms of enabling robots to learn complex tasks entirely from scratch. In the next five to 10 years, we may see significant advances in robot learning capabilities through this line of work.”
The Defense Advanced Research Projects Agency, Office of Naval Research, U.S. Army Research Laboratory and National Science Foundation helped support this research.

The Case Against Probate: False Ruling Invalidates Black Professor’s Estate Plan, Ignoring 28-Year Relationship
Zakiya Folami Jendayi, beneficiary of Head’s estate, states that “The errors, ranging from misstatements of fact, omissions of critical evidence, and reliance on false arguments and testimony, formed the basis of Judge Sandra K. Bean’s ruling against me, Dr. Head’s previous student, mentee, sorority sister and long-time friend,and despite the fact that I was her chosen, power of attorney, Advanced Healthcare Directive agent, trustee, executor and sole beneficiary.”

Part 5
In a shocking miscarriage of justice, a California probate judge issued a Statement of Decision on March 28 riddled with numerous documented errors that invalidated the estate plan of esteemed Black Studies professor Dr. Laura Dean Head.
The ruling from the Alameda County Superior Court’s probate division in Berkeley has sparked outrage from advocates for probate reform, community members and civil rights activists, who say the decision reflects deep flaws in the probate system, blatant disregard for due process, and the wishes of the ancestors. Judge Sandra Bean’s ruling reflects a repeated outcome seen in Black and Brown communities.
Zakiya Folami Jendayi, beneficiary of Head’s estate, states that “The errors, ranging from misstatements of fact, omissions of critical evidence, and reliance on false arguments and testimony, formed the basis of Judge Sandra K. Bean’s ruling against me, Dr. Head’s previous student, mentee, sorority sister and long-time friend,and despite the fact that I was her chosen, power of attorney, Advanced Healthcare Directive agent, trustee, executor and sole beneficiary.”
Reading court transcripts, the most egregious violations according to Jendayi reveal a pivotal point in the ruling that rested on a letter from Dr. Stephan Sarafian of Kaiser Permanente, who misidentified Dr. Head as male, misstated the day, month, and year, and asserted Head lacked capacity.
Under cross-examination, he reversed his opinion and admitted under oath that he never conducted a mental evaluation, did not diagnose Dr. Head with incapacity, did not write the letter, and stated he merely signed it “in case it was needed in the future.”
Despite Sarafian’s perjury, on Oct. 17, 2024, the California Court of Appeal upheld the lower court decision that relied on Sarafian’s discredited letter to invalidate Dr. Head’s estate plan, ignored Jendayi’s requests to impeach his testimony and dismiss Sarafian’s testimony and letter that both the Kaiser Grievance Department and the Medical Board of California denounced.
In her ruling, Judge Bean agreed with the false argument by attorney Leahy, which alleged that Jendayi provided the names of the beneficiaries to Head’s estate attorney, Elaine Lee. Bean made this decision despite Lee’s sworn testimony that Dr. Head had met with her alone, behind closed doors, and made the independent decision to leave her estate to Jendayi.
According to court records, Judge Bean reversed the burden of proof in the undue influence claim before any of Jendayi’s witnesses testified, forcing Jendayi to disprove allegations that were never substantiated by witnesses or records.
Bean ruled: “Respondent took Dr. Head to her apartment where she assumed complete control of Dr. Head’s day-to-day care, medical care, and all aspects of her life.” Jendayi proved that statement was false.
Bean also ruled that Respondent controlled Dr. Head’s necessities of life, food, and hospice care, despite zero testimony or documentation supporting any of those claims.
The court reduced Jendayi’s role to “a friend who, at best, cared for Dr. Head during the final two months,” totally ignoring 28 years of friendship, testimony, evidence, letters of recommendation, emails, and medical records.
Exhibits confirming Dr. Head’s intent and capacity, including the discredited medical letter, Exhibit 90, were omitted or misrepresented in the judge’s final decision.
Jendayi says, “The injustice within the probate justice system is devastating, traumatizing and financially depleting. It’s nothing short of legalized crime!”
Jendayi is now appealing to the Supreme Court of the U.S. with a petition citing denial of due process, judicial misconduct, and systemic bias in probate courts.

The Progressive Missionary Baptist Church of Berkeley is celebrating its 90th church anniversary on Sunday, May 18 at 10 a.m. at 3301 King Street in Berkeley.
Dr. Earl C. Stuckey, Sr., who has served as Progressive Missionary’s pastor since September 1977, said the church also delights in the fact that it has hosted only five pastors in its 90-year history, including Pastors James E. Moore, H. A. Green, F. Douglas Farrell, and Edward Stovall, who served for 37 years.
The celebration will feature Pastor Darnell Manuel of the Union Baptist Church in Vallejo as guest speaker, along with many other special presentations.
Those who wish to share in Progressive’s history can purchase a 100-page full-colored souvenir book for $25.
The church boasts a number of notable people who either regularly attended or became members of the church since its inception, including former Alameda County Supervisor Keith Carson, Oakland mayoral candidate Loren Taylor, and one of the organizers of the Gospel Music Workshop of America, Helen J. H. Stephens.
Pastor Stuckey often remarks how longevity flourishes at the church — it boasts 13 centenarians (people who have reached 100 years or more). Currently, it has one centenarian who is still surviving, Mrs. Dorothy Chambers, and 14 members who have reached 90 years or more.
Recently, on Feb.17, the pastor and his wife Kay Frances, celebrated their 73rd wedding anniversary.

Faces Around the Bay: Author Karen Lewis Took the ‘Detour to Straight Street’
“My life has been a roller-coaster with an unlimited ride wristband! I was raised in Berkeley during the time of Ron Dellums, the Black Panthers, and People’s Park. I was a Hippie kid, my Auntie cut off all our hair so we could wear the natural styles like her and Angela Davis.

I met Karen Lewis on a park bench in Berkeley. She wrote her story on the spot.
“My life has been a roller-coaster with an unlimited ride wristband! I was raised in Berkeley during the time of Ron Dellums, the Black Panthers, and People’s Park. I was a Hippie kid, my Auntie cut off all our hair so we could wear the natural styles like her and Angela Davis.
I got married young, then ended up getting divorced, raising two boys into men. After my divorce, I had a stroke that left me blind and paralyzed. I was homeless, lost in a fog with blurred vision.
Jesus healed me! I now have two beautiful grandkids. At 61, this age and this stage, I am finally free indeed. Our Lord Jesus Christ saved my soul. I now know how to be still. I lay at his feet. I surrender and just rest. My life and every step on my path have already been ordered. So, I have learned in this life…it’s nice to be nice. No stressing, just blessings. Pray for the best and deal with the rest.
Nobody is perfect, so forgive quickly and love easily!”
Lewis’ book “Detour to Straight Street” is available on Amazon.
