Tiny Desktop Robot Has Radar No comments by: Zoe Skyforest July 31, 2026 Title: Copy Short Link: Copy One thing our futuristic world is largely lacking in is droids and robot companions and the like. [solitary dev] is helping to rectify that problem by building a little robot called TongDou. As [solitary dev] tells it, TongDou is a “tiny open-source desktop gremlin.” An ESP32-S3 serves as TongDou’s brain, buried inside a tasteful brass tube chassis. An OLED display is TongDou’s face, and he uses a pair of wheels driven by gearmotors for locomotion. A speaker plays back pre-recorded voice lines, while a 24GHz radar and an IMU enables TongDou to keep track of the space it’s moving through. They are publishing the design files on Github so other makers can build their own if so desired.
