  • Japan holds a leading position in the development of humanoid robots, with machines like Honda’s Asimo.
  • Late last year Toyota unveiled a new humanoid robot and master slave device that stands 5 ft. tall and can mimmick an operator’s movements.
  • Countries with a dwindling workforce population and an aging population will find humanoid robots fill a void.
  • A new technology called Real-Haptics lets human motions be stored and reproduced, a concept known as the ‘Internet of Actions.’

At a high school graduation ceremony in Japan’s Hiroshima Prefecture, each student received a diploma and then walked over to a small humanoid robot, paused, and bowed deeply. The robot waved its small arms in response. It was the embodied presence of Takanobu Nagaoka, a 55-year-old teacher at the school who was diagnosed with ALS two years ago. Unable to travel due to deteriorating motor skills, he “attended” the event as OriHime, a simple tabletop droid with a camera, microphone and speaker. It’s the creation of Tokyo start-up Ory Laboratory and one of a new breed of machines known as “avatar robots” that could change the way people interact and work.

“OriHime can be used not only by hospitalized people but students who refuse to go to school and even mothers who cannot go to work because they’re taking care of kids,” says Kentaro Yoshifuji, CEO of Ory, which has rented out about 260 units. “This technology could help redistribute manpower so the right person can work in the right place in a more smooth fashion.”

Humanoid evolution

Aside from giving disabled people a new level of empowerment, avatar robots present myriad possibilities for work with concomitant economic benefits. If you’re a doctor, for instance, you could log into a robot in Antarctica or on a space station to tend to a critically ill person. Robots as a whole are beneficial for economies. According to a 2017 study by the London-based Centre for Economics and Business Research, robotics investments have “contributed around 10 percent of GDP per capita growth in OECD countries from 1993 to 2016″ and offer “better long-run value for money than investments in financial services, real estate or transportation.”

Avatar robots are still experimental, but if the market for collaborative robots is any indication, there could be significant demand. Also known as cobots, collaborative robots are covered with soft materials and can work alongside people in assembly and other jobs. The market for cobots is expected to grow to $12 billion by 2025, according to Barclays Equity Research. Remote operation of robots for work outside the factory, however, is already well established. Intuitive Surgical, for instance, has sold over 4,200 of its da Vinci surgical robots, which reproduce a surgeon’s hand motions through small incisions in a patient’s body during operations such as hysterectomies; benefits may include shorter recoveries.

Many workers around the world may be concerned about losing their jobs to automation, but the risk varies from country to country. A recent OECD study estimates that 33 percent of jobs in Slovakia are “highly automatable”, but only 6 percent in Norway, though the authors caution that “the actual risk of automation is subject to significant variation.” Nonetheless, unions are protesting encroaching machines. Earlier this year, Unifor, Canada’s largest private-sector union, decried a decision by Canadian energy company Suncor to introduce driverless ore-hauling trucks in the Alberta oil sands; the move could replace hundreds of heavy machinery operators.

Japan has embraced automation in the factory and elsewhere. It has long held a leading position in the development of humanoid robots, with machines like Honda‘s Asimo exhibiting remarkable abilities in locomotion and dexterity. It’s now integrating that technology with user interfaces to project human abilities into mobile machines.

Late last year, Toyota Motor unveiled a new humanoid robot and master-slave control device that it describes as the world’s first system that allows operators to intuitively control the robot’s entire body. Weighing 75 kg (165 pounds), and standing 154 cm (5 feet) tall, the T-HR3 has 32 joints, each equipped with a new type of torque sensor that has a high degree of sensitivity, giving the robot flexibility, balance and the ability to recover from collisions.

During a demonstration at the iRex 2017 robot trade show in Tokyo, held in November and December 2017, the T-HR3 went through some pre-programmed and live-controlled motions. It balanced on one foot and then pivoted into a Tai chi-style pose. It then synchronized with its Master Maneuvering System, which is basically a seat for a human operator with arm sensors for motion tracking. It works with a head-mounted display and sensor glove to convey a sense of sight and touch. During the demo, the robot immediately reproduced all of the operator’s movements, deftly opening and closing its fingers, manipulating plastic blocks and grasping a rubber ball.

The T-HR3 is the automaker’s third humanoid platform, following a trumpet-playing robot in 2005 and a violinist droid in 2010. While those machines showcased manual dexterity, Toyota is imagining more practical uses for the T-HR3, including everything from childcare to work in construction, disasters and outer space, that would give robots human-like motor skills while keeping people out of harm’s way.

“In the near future, robots will start doing simple household chores and nursing care work, allowing people to make effective use of their time,” says Tomohisa Moridaira, a manager in Toyota’s Partner Robot Division. “In contrast to industrial robots that operate in isolated environments, we want to create robots that can coexist safely with people. I think T-HR3 will evolve into a more robust, but lightweight robot that is not easily broken.”
