DJI’s Latest Take on Robotics is a Lot More Fun than You Think

DJI, best known for its high-flying drones, is taking a more terrestrial approach with its latest product, an educational robot named RoboMaster S1. Available for $499 in the US, the S1 offers kids and adults interested in learning Python ways to code and play solo or with others.


S1 (which stands for Step 1), comes with a companion RoboMaster app (for iOS and Android), where you can program six different types of basic functions in Scratch 3.0 block-coding or the more advanced Python language:

  • Line Follow: Use the RoboMaster app to create a path for the S1 to follow
  • Vision Marker Recognition: The S1 can read 44 different “Vision Markers,” which consist of letters, special characters and numbers. You can program the S1 to conduct a different function upon scanning a marker.
  • Follow Mode: The S1 can detect a person in its field of view (FOV) and follow it around.
  • Clap Recognition: Make the S1 do different things based on how many times you clap.
  • Gesture Recognition: Control S1 with different hand gestures. Some of DJI’s drones already have this feature, allowing users to make the device follow them with a wave, for example.
  • S1 Recognition: Program S1 to do various movements when it sees another S1 robot.

There are also more advanced coding possibilities for skilled programmers. This includes making S1 run better by tweaking its wheels’ torque, or coding your own moves, like a counterattack, for robot fights.

To help guide coding students on the right path, RoboMaster’s app has a “Road to Mastery” project-based series of coding tutorials. The app also has a “RoboAcademy,” stocked with video tutorials and programming guides. DJI says it will update both regularly.

DJI claims the S1 has a good amount of processing power, partially thanks to its industrial-grade CAN-bus cable (for letting microcontrollers communicate) enabling high bandwidth and stability even during multi-tasking.

Like all fun robots, the S1 has a violent side. It’s equipped with 31 sensors, including six on its body that let it know when it’s been hit in combat. And in a Nerf-like turn of events, S1 has a non-toxic trick up its sleeve: a gel bead-slinging infrared gimbal. The beads are made of a “composite material” that you’re supposed to submerge in water to soften before using it as ammo. For further safety, the blaster can only shoot at a 10-degree or smaller angle. Still, the S1 comes with safety goggles.

“Every robot has a speedometer built in its blaster to measure the speed of when a gel bead is launched and a gel bead will not launch if its previous launching speed is higher than the maximum speed (26mps),” a DJI spokesperson told us. “The blaster was specifically designed… If those objects were to be launched through the blaster, their launching speed will be too low to cause any injuries.

With its first-person view (FPV) object recognition camera, you can see from the S1’s point of view in real-time from your device. It also has six pulse width modulation (PWM) control ports so skilled enthusiasts can add third-party hardware and communicate with other S1s.

The S1 moves via four Mecanum wheels, the same kind of omnidirectional wheels used in industrial containers and forklifts, with a dozen rollers each.
