Lobot was an exercise to design a programmable, expandable, Bluetooth controlled robot at the lowest possible cost.

Having purchased a few robot kits for my kids I noticed the thing they loved most was just building something and making it drive around. Most of the kits that actually have a programming/expansion aspect seem to be relatively expensive, or make it difficult to get to that point of being fun for kids to play with. Lobot is designed to be both cheap and relatively easy to get to a point where you can drive it around.

The design is based on the popular Espressif ESP32, so it has a heap of connectivity options and plenty of functionality for you to take advantage of. There are also different options for programming the ESP32. I use Arduino IDE.

In the future I will release expansion boards for things like sensors and servos, but the basic design has plenty of interfaces and IO that you can use to start experimenting:

• WiFi interface (the demo firmware includes a WiFi over-the-air updater)
• Bluetooth interface
• UART
• SPI
• I2C
• Digital IO
• PWM Outputs
• Analogue Inputs
