Choosing which of the many robotic [microcomputer/microcontroller|microcontroller] platforms ([Raspberry Pi], [Arduino], [micro:bit|microbit], etc.), which of the various programming environments (graphical, [Python], MicroPython, C++, assembly language), and then which specific robot has as much to do with a sense of one's goals and requirements as with which robot is most appealing to the eye. There's also the question as to whether to purchase a ready-made robot, a kit, or design-your-own from either an existing system or an entirely bespoke robot from available parts (truly "on your own"). And also whether to purchase something that grows with one's experience or is limited to the specifics of the chosen robot. Having the flexibility of multiple programming environments is a factor in any robot's favour.

And also whether to purchase something that grows with one's experience or is limited to the specifics of the chosen robot. I don't consider "age level" really much of a factor since it's pretty clear that a 10 year old and a 70 year old may share the same level of previous experience, interest, and ingenuity. But having the flexibility of multiple programming environments is a factor in any robot's favour.

That's a lot to think about.
The [mini-Zumo robots|Zumo Robot] are appealing if competition within a group is a requirement. These are generally Arduino-based, so they'd be programmed in C++. But very popular but they're somewhat limited beyond line following and knocking each other out of the ring.
I'm a bit of a fan of the 4Tronics products, having used their PiconZero Raspberry Pi controller. Their robots are visually appealing but less expandable and likely a bit more fragile than the aforementioned choices. They typically have a marker holder to let the robot draw on a piece of paper, but frankly I'd be concerned with having a marker-laden robot running over my wood floors. Line following and exploration are probably more interesting and educational endeavours.

For a "club robot", i.e., something that a group of people can cooperatively work on together, sharing ideas and designs, something that has a wide range of programming opportunities, and something that is very well-documented and used by a ''huge'' number of people, well, the __BBC micro:bit__ platform is hard to beat.

The micro:bit can be used as a learning tool outside of robotic applications, and because of its edge connector needn't be soldered or permanently connected to a robot.

With that said, our first choice for a micro:bit robot is the __Waveshare Alphabot__, as it has a lot of features for the money, and is probably the most durable of the micro:bit robots listed below. The DFRobot __micro:Maqueen Plus__ or __micro:Maqueen Lite__ are likewise great choices. The Plus has a lot of expansion capabilities, even an AI "smart" camera that can be trained to recognise objects and colours.

How old does someone have to be to use a micro:bit? That's not an easy question to answer, but "age level" is not so much a factor since it's pretty clear that a 10 year old and a 70 year old may share the same level of previous experience, interest, and ingenuity. Success is more about enthusiasm, curiosity, and how much time one devotes to learning than anything else.

It's included in the list here so you can see that a micro:bit robot need not be limited by any notion of the simplicity of its controller. You can also purchase a version of the Rover that uses a Raspberry Pi Zero W.

This robot is perhaps not as pretty as some of the others (no rows of rainbow flashing LEDs, though it does have four RGB LEDs underneath its chassis) but is probably one of the more advanced, durable and better-designed of the micro:bit robots. It is also available for [Arduino] and [Raspberry Pi].

__micro: Maqueen Plus__ is an advanced version of micro:Maqueen Lite (4.0), which is more powerful and intelligent. Optimized with better power management and larger capacity power supply, it can be perfectly compatible with [HuskyLens AI Vision Sensor |https://www.dfrobot.com/product-1922.html] which makes it an accessible AI robot teaching tool.

In addition, micro:Maqueen Plus comes with a larger and more stable chassis, more built-in functions and more expansion ports, it is not only suitable for classroom teaching, but also can be suitable for after-school extended exercises and robot competitions.
At line 87 added one line
There are also expansion kits available which add mechanical actuators (e.g., gripper, loader), a gamepad controller, and a HuskyLens (AI camera). As compared with the Lite version it also has a battery charging circuit (for a 2500mAh LiPo battery), motor encoders with a PID controller, large RGB LEDs up front, a lot more IO ports and even a line tracking map.
