Moving objects controller

Description

Sends a (Steer, Speed) couple over UART. These values are computed :

• from 2 ADC, e.g. an analog joystick wired to ESP32.
• from pitch/roll got from a SensortagBLE server over a BLE connection.

Usage

From that you can control some hacked hoverboards

Folder structure

ctrl/steer_speed_ctrl

Arduino sketch running on ESP32 targets. It can either :

• get roll, pitch over Bluetooth from a customizedCC2650. It acts as a Bluetooth client connecting.
• get two axis analog joystick values and converts these data to a (steer, speed) target sent over UART. It is sent as 2 int16_t in Little Endian.

It also displays some info about speed, control type on a led strip. It can adjust control from smootth to sport mode using a potentiometer.

cc2650_stk_fw

Binary of cc2650 sensortag firmware, it must be flashed to a Sensortag. When power button is pressed, ESP32 connects/disconnects to it.

hoverboard_firmware_hack

Hoverboard hacked firmware to flash to an existing hoverboard.

Wheel chair use case

A wheel chair can be controlled with a Joystick or over Bluetooth. People siting on it will have lot a fun to control it using joystick. They will be surprised when you will take chair control pressing sensortag power button and moving it!
