Specifications

The following is a list of key components of Boxbot:

Computation

  • Arduino Mega Microcontroller

Chassis

  • 16 gauge plain mild steel plate

Detection

  • 11 IR receiver sensors

  • Ultrasonic distance sensor

Powertrain

  • 2x 37mm DC motor w/ 64 CPR encoder

Retrieval

  • Horizontal beam w/  pressfit neodymium magnet

Power

  • 8x AA batteries for the DC motors

  • 1x 9V battery for Arduino Mega

Boxbot will use a combination of infrared sensors for long range detection and ultrasonic sensors for close proximity sensing to detect an objecting emitting infrared light.

 

The Arduino Mega microcontroller will process this analog data and send a PWM signal to two DC motors. The motors will spin independently of each other and will therefore be able to achieve straight line movement as well as pivoting motion.

 

Once the robot reaches the object, the magnetic force from the neodymium magnet will attract and pull the magnetic object to the robot. The robot will then return to the specified location.
