Flyer-Delivering Lego Robot

DFRobot Jun 27 2013 219

High school student Leon Overwheel built this sick flyer robot to hand out leaflets Rye High School science fair. It uses an ultrasonic sensor to detect a visitor, then pulls a flyer off of a pile and hands it to the visitor. My favorite details are the Fergelli linear actuators and the Mindsensors Flexi Cables. He even hacked together a NXT-Power Functions adapter cable.

Device-wise, the robot consists of the following functional parts:

  • 2 Mindstorms NXT Intelligent Bricks (1.0 & 2.0)
  • 2 100mm Firgelli Linear Actuators
  • 2 Mindstorms NXT Motors
  • 1 LEGO Technic Small Motor
  • 4 Mindsensors Flexi-Cables for NXT (1 meter long & 1.5 meters long) 
  • 1 Custom-made NXT-Technic Motor cable
  • 3 Touch Sensors
  • 1 Ultrasonic Sensor
