What are the supporting modules?

Bittle robot dog supports a few modules such as sound sensor, light sensor, touch sensor, and camera module. You can connect common modules using the 2.54mm connectors on NyBoard V1. Although Nybble robot cat uses the same NyBoard V1 as Bittle, there’s no easy way to mount the modules.

What connection methods do Petoi robots support?

Petoi robots support wired serial connection via USB programmer, Bluetooth dongle, and WiFi dongle.

Do your robots support voice-based input?

If you equip them with a sound module, they can be programmed to do voice recognition and act on voice commands accordingly.

What single board computers do your legged robots support?

Our open source quadruped robots support communication with optional microcontrollers or computers such as Raspberry Pi, Nvidia Jetson Nano, and micro:bit through wired or wireless connections. Both Nybble and Bittle support direct connections to Raspberry Pi (smaller models like Pi 3A+ and Pi Zero are preferred). For larger setups, extra support structures may be 3D-printed. Communication is handled via serial UART, with Python modules and sample codes available in OpenCat/SerialMaster. Note that Jetson Nano is too large for the robots, so only wireless connections are recommended.
