Multi-Function Cordless Drill with Wire Detection

As the Internet of Things (IoT) continues to expand into the home appliances market, devices such as smart drills will need to be able to communicate with a smartphone using common wireless communication protocols such as Bluetooth® or Wi-Fi. This energy-efficient intelligent cordless drill solution includes an electric wire in wall detection feature, as well as additional programmable features that include angle of drilling (vertical/horizontal/any angle), RPM limit for plastic materials, torque limit as an option to a mechanical switch, distance measurements, Bluetooth Low Energy (LE) connection to a smartphone for easy user setup, and optional haptic indication of electric wire detection.

System Benefits

  • Electric wire in wall detection integrated in removable dust collector increases safety and removes the need for additional dedicated tools
  • Indication of horizontal or vertical (or programmable angle) removes the need for additional jigs or tools
  • Low cost Bluetooth LE allows users to comfortably control the drill on a smartphone
  • Brushless motor with precise toque control increases efficiency and power and decreases overall weight
  • Wide angle observation display (IPS or OLED panel)

Target Applications

  • Cordless drill with embedded safety and advanced functionality
