This tutorial is how to make a cheap yet functional haptic feedback vest.

Step 1: Materials List

  • 1 Vest (Ideally with pockets or compartments to hold electronics)
  • 2-4 Ultrasonic Sensors
  • 1 Vibration motor for every sensor
  • Wires
  • Arduino
  • Transistors
  • Arduino ProtoShield

Step 2: Procedures (Wiring)

Step 1: Connect ultrasonic sensors to power

Step 2: Connect input/output ports of the ultrasonic sensors to the analog ports of the Arduino

Step 3: Set up power wires for transistors that are connected to the motors in a parallel circuit (Positive voltage connects to the first lead of the transistor)

Step 4: After connecting transistors to power, connect each transistor to a different port on the Arduino (Data wires connect to the middle pin of the transistor)

Step 5: Connect motors to the transistors (One side of the motor connects to the third pin and the other side connects to ground)

Step 3: Procedures (Programming)

The program is set to vibrate if anything is within 2 feet. adjust the values as needed and if there is lag lower the delays. this program works with no issues; to add more sensors just copy and paste what happens from each previous sensor and adjust everything accordingly.

Step 4: Sensor Covers

For your vest you can design the covers anyway you like. Just be sure to make the cover a little bigger on the CAD system because if you were to 3D print it it would shrink and may not fit if it shrinks too much. I have included the covers I made with all the dimensions accurate to the VEX Ultrasonic sensors.

this would be awesome to use with the oculus rift!
+1 That! Ha
<p>Could make or modify this to use on a motorcycle. Be able to sense cars. Thanks for the idea. Good job</p>
They've actually tested that before. Can't remember exact numbers but it was staggering how much it drops the number of accidents.
Nice project.<br>Note that the way you connect the transistor is for P-type transistors, maybe nice to mention;)
<p>Thank you guys for the feedback! It is definitely appreciated and will be taken into consideration as we work more on the vest with (hopefully) better materials. With this being a summer High School project, it's great that its gotten 653 views and featured less than a day after it was originally posted. Thank you guys again!</p>
<p>Fantastic project - thanks for sharing it with us!</p>
