Well, OK, just in theory. But this amazing NXT-controlled LEGO robot by Hknssn can build its own tower, and since the robot rides up the tower with each new piece it places, there’s theoretically no limit to how high it can build as long as it continues to be fed pieces.
Make a robot friend with Adafruit’s CRICKIT – A Creative Robotics & Interactive Construction Kit. It’s an add-on to our popular Circuit Playground Express, FEATHER and other platforms to make and program robots with CircuitPython, MakeCode, and Arduino. Start controlling motors, servos, solenoids. You also get signal pins, capacitive touch sensors, a NeoPixel driver and amplified speaker output. It complements & extends your boards so you can still use all the goodies on the microcontroller, now you have a robotics playground as well.
