Moody Mush is an interactive, mushroom‑shaped robot built by SayaNIGHT. It has three modes of operation. In Mode 1, it functions as a desk lamp; the LEDs and cap (the head portion) are controlled with an IR remote. In Mode 2, the LED colors are adjustable with the same remote, but the robot also reacts to touch. Different movements and sounds occur depending on the type of touch (a short touch is treated as a poke, a long touch as a pat or hug). Mode 3 is a fully interactive mode in which Moody Mush showcases different moods and matching colors based on touch. The color mapping ranges from red for a positive, happy, or dancing mood, through green for a neutral or snuggle mood, to violet for a negative, refusal, or angry mood.
All parts were 3D printed in white, with a structural design in the internal walls of the Moody Mush cap. Cap movement is driven by two SG90 servo motors mounted inside the body. A total of nine touch sensors are placed around the cap to detect touch responses. MakerPort - a universal hub for connecting LEDs, music, touchpads, and mechanical parts such as servo motors was used as the controller. This all‑in‑one solution simplified the build by avoiding the need to write code for more complicated hardware. Overall, the build is really cool and interesting.
