The most striking robot in IEEE Spectrum’s Video Friday roundup is built to change its body plan: Northwestern University researchers combine autonomous modules into robots with different numbers of legs. The 13 March 2026 collection also features a MagicLab robot panda, delivery and humanoid robots, teleoperation, and educational robotics. These are demonstrations and clips—not a head-to-head test or a catalog of products for sale.
What is the modular robot in the roundup?
Northwestern’s legged “metamachines” are made from modules that can be assembled into different configurations. Northwestern describes each module as an autonomous robot with its own motor, battery, and computer; the legs used as building blocks are half a meter long. Rather than relying on one fixed chassis, researchers can combine the units into three-, four-, or five-legged designs.
The idea is to make a robot that can be reconfigured for movement in irregular environments. Northwestern reports that AI-generated configurations were assembled and tested outdoors on gravel, grass, tree roots, leaves, sand, mud, and uneven bricks. The researchers also report that the machines can keep moving after damage or reconfiguration. That finding does not mean every body plan performs equally well, or that the system is ready for general deployment.
Study leader and corresponding author Sam Kriegman said, “These are the first robots to set foot outdoors after evolving inside of a computer,” in Northwestern University’s 6 March 2026 report. That is Kriegman’s characterization of the work, not an independently verified ranking of all robotics research.

IEEE Spectrum’s roundup reproduces the research description: “Here, we introduce highly athletic modular building blocks and show how they enable the automatic design and rapid assembly of novel agile robots that can ‘hit the ground running’ in unstructured outdoor environments.”
Is the robot panda for sale?
The roundup includes a MagicLab robot-panda clip, but IEEE Spectrum does not identify a retail model or provide its price or specifications. The video is not enough to establish that viewers can buy the panda shown, so it should be treated as a demonstration rather than a product recommendation.

What else is in the video collection?
The roundup brings together different kinds of robotics rather than systems that can be ranked on one shared performance scale. Its clips include delivery and humanoid robots, teleoperation, semantic exploration, robot-safety software, a reconfigurable response robot, an educational-robot segment, and a Disney Research keynote. The videos and brief descriptions do not establish common benchmarks for speed, reliability, price, or readiness.
For context, MIT CSAIL’s M-Blocks are a separate research project: self-transforming cubes that move using internal flywheels and connect magnetically. MIT News reported that 90 percent succeeded in forming a line in one particular experiment in 2019. That result applies to that test, not to Northwestern’s legged robots or the other clips. MIT Professor and CSAIL Director Daniela Rus summarized the name this way: “M stands for motion, magnet, and magic.”

Can you try educational robotics yourself?
Sphero appears in the roundup’s education-robot segment, but it is separate from Northwestern’s research demonstration. Sphero’s official pages identify BOLT+ as a programmable coding robot, making it a learner-oriented option for hands-on coding activities—not a version of the modular metamachine or the robot panda. Check the official Sphero BOLT+ page for current product information.

How to read these robot videos
- Look at the task: Outdoor locomotion, delivery, exploration, education, and teleoperation pose different problems.
- Notice how the robot is controlled: A robot may operate autonomously, be teleoperated, or be programmed by a learner; those are not interchangeable capabilities.
- Separate research demonstrations from products: The roundup does not establish that the featured research robots or panda are available to buy.
- Avoid cross-clip performance claims: The roundup does not present a common test setup or comparable measurements.
