ESC

Electronic Speed Controller

Description

The Electronic Speed Controller (ESC) is necessary to control the BLDC motors used for the wheels

Requirements

1. Bidirectional Control

• The motors need to run both forwards and backwards. ESC must be bidirectional

2. Customization

• Ability to configure acceleration curves and braking is necessary

3. Communication Interface

• The ESCs should accept control inputs from an ESP32-WROVER-IE (e.g. PWM, UART, SPI)

• The ESC should provide feedback which can be used to improve the control precision. (e.g. EMF)
