Elephant Robotics Technology Myarm 300 PI 2023 (4011200001)

Most robot arms ask you to learn a controller before you can learn the robot. The Elephant Robotics Technology Myarm 300 PI 2023 (4011200001) turns that around: its brain is a Raspberry Pi 4B running Ubuntu Mate, so anyone who has ever opened a terminal window already knows how to talk to it. The arm is the peripheral, and the computer is built into its body.

Background

Elephant Robotics and the myCobot lineage

Elephant Robotics builds compact collaborative and desktop robot arms for education, research and light development work. Its catalog has grown around a simple idea: a robot arm should be approachable enough for a classroom and still serious enough for a lab bench. The myCobot family carries that idea in several sizes and control options, and the myArm line extends it toward a more capable, more industrial structure.

The myArm 300 Pi belongs to that line. It is designed to be 100% compatible with myCobot accessories, so structure installation and software control carry over from the smaller arms. A team that has already built grippers, mounts or end tools for a myCobot does not have to start again. It is also compatible with the M5stack ecosystem, which provides PWM and IO and supports the connection of PWM motors, infrared sensors and other M5stack product hardware.

An integrated 7-DOF arm with a computer inside

The myArm 300 Pi is an integrated 7-DOF robot that uses the Raspberry Pi 4B as its main control board. Seven degrees of freedom give the arm one more joint than the six that many desktop arms offer, which matters when you need to approach a target from different angles or work around an obstacle. To drive those joints, the arm houses 7 high-precision all-metal magnetic encoder motors in a very small space, with structural complexity comparable to industrial products.

The main control is a Raspberry Pi 4B 4G. Two ESP32 chips act as auxiliary control. The result is a self-contained platform: you can plug in a display through its two microHDMI ports, attach a keyboard and mouse to the USB ports, and program the arm directly on the device, or connect to it over Ethernet or WLAN from another machine.

What makes the myArm 300 Pi different from a typical desktop arm?

The difference is where the intelligence lives. Many small arms depend on a separate computer, a microcontroller board or a vendor application to do anything useful. Here the Raspberry Pi 4B 4G is part of the arm, with a Broadcom BCM2711 quad-core processor at 1.5GHz and 4 GB of LPDDR4 memory. The operating system is Ubuntu Mate 20.04, so you work in a familiar desktop environment instead of a closed controller.

The software is ready as well. ROS1, ROS2 and Python are built in, which means a robotics student can move from a first script to a ROS node without installing a toolchain first. For beginners, myBlockly offers block-based programming on the same machine. One arm can therefore serve a first-year class and a graduate research group, each at its own level.

The second difference is structural. Seven joints in a 300 mm working radius, driven by metal-geared magnetic encoder motors, give a layout closer to an industrial arm than to a toy. Repeatability is ± 0.5 mm, a figure that suits demonstrations, vision experiments and small-part handling where you want consistent results from run to run.

What should I keep in mind about payload and camera?

The maximum load is 200 g, so this is an arm for light tools, small grippers, sensors and lightweight parts, not for heavy handling. Plan your end effector with that limit in mind. At 1.5 KG net weight, the arm is easy to move between a bench and a classroom cart.

The arm does not come with a camera. A camera is optional, and any USB interface camera can be connected, using the USB 3.0 or USB 2.0 ports. That freedom lets you choose a camera that suits your vision project instead of working with a fixed one. Power comes from a DC 12V-5A adapter.

Who is the myArm 300 Pi 2023 for?

Universities and technical schools are the clearest fit. The arm gives students a real 7-DOF kinematic chain, ROS1 and ROS2 support, and a Linux computer in one unit, which makes it practical for courses in robotics, computer vision and control.

Research and development groups can use it as a low-barrier test platform for motion planning and redundancy, then bring the results to larger hardware later. Makers and integrators who already own myCobot accessories will value the full accessory compatibility and the M5stack connection options.

If your work needs a different arm format, you can compare it with the Elephant Robotics Technology Myarm C650 (4011200002) or the Elephant Robotics Technology Myarm M750 (4011200003) in the same myArm line. If you prefer a six-axis desktop arm with the same Raspberry Pi approach, look at the Elephant Robotics Technology Mycobot 320 Pi Robot Arm (4010100023). Our full range is in the Robot Arms category.

What is the myArm 300 Pi used for?

1. Teaching robotics. Students learn kinematics, ROS and Python on a real seven-joint arm, with no extra controller to set up.
2. Block-based programming. myBlockly lets beginners build motion sequences visually before they move to code.
3. Vision experiments. Add a USB camera and test object detection, tracking and pick-and-place routines.
4. Research prototyping. Try motion planning and redundant-arm strategies in ROS1 or ROS2 on a compact platform.
5. Sensor and accessory projects. Use the PWM and IO connections to link M5stack hardware, infrared sensors and PWM motors.
6. Light demonstrations. Show repeatable small-part movements at workshops, exhibitions and training events.
