At Tesla’s AI Day this past week, Elon Musk unveiled the Tesla Bot, an android that would build on the company’s autonomous vehicle and artificial intelligence research. The lightweight robot would work in spaces designed for humans, said Musk. However, it will be a while before an actual, “helpful” robot can match the moves of the dancer at the event and be useful. A prototype is due next year.

Most theme park visitors are familiar with the performers wearing large, hot costumes of popular characters. Walt Disney Imagineering Research & Development Inc. is working to build robot entertainers, such as this prototype of Guardians of the Galaxy‘s Groot shown here. It’s a step up from the creaky animatronics of decades past, and the small form factor could help overcome the “uncanny valley.”

​Speaking of the uncanny valley, Promobot showed its Robo-C model this month. The seated humanoids had realistic human-like hair and skin, and the Russian company said they use artificial intelligence to interact with humans. The robots have multiple degrees of freedom and they could be teleoperated.

Ubtech Robotics’ Walker X, most recently demonstrated at the World Artificial Intelligence Conference in Shanghai earlier this month, looks like Honda’s now-discontinued Asimo. It probably doesn’t yet have general AI, but it’s a good example of the service and companion robots being designed today.

While not fully humanoid, Oregon State University’s Cassie last month made history by completing a 5 km (3.1 mi.) course in under an hour. The legged robot does not have a torso, but this distance is important because walking consumes more energy than moving on wheels.

Digit is a direct descendant of Cassie, and Agility Robotics has added a sensor-filled torso and arms. The robot is intended for deliveries and—unlike most robots on this list—it is in commercial production.

While it was not among the robots initially announced for the 2021 Tokyo Olympic Games, Toyota‘s CUE5 sank some impressive shots. However, the robot moved on wheels and has been in development for about four years. CUE5’s numerous sensors enable it to calculate the best trajectory for a basketball.

The University of Hamburg in May released a report on Wolfgang-OP, a “robust humanoid robot platform for research and competitions.” It was trained in simulation and participated in the annual RoboCup competition, sponsored by an international league dedicated to promoting science and technology.

CloudMinds Technology Inc., which raised $153 million in April, said its XR-1 Service Robot will do actual work. The company‘s cloud-connected robot is intended for the retail, education, healthcare, and hospitality markets. Whether it can survive the U.S.-China trade conflict or SoftBank’s retreat with Pepper remains to be seen.

Hanson Robotics said it plans to mass-produce its Sophia robot and others by the end of this year. Sophia has been featured at events and in videos with human-like interaction, but they are a combination of clever programming, cloud AI, and teleoperation. The Hong Kong-based company said its service robot, with a humanoid head, arms, and torso but wheeled base, could be useful in the healthcare, retail, and educational markets.
