This chap sits in my shirt pocket, just like in the contest icon, and goes with me wherever, ready to shine his light upon the world...
Anyway, notice how he seems to look down, wearing a slight smile? That's because he gets happy and blinks his lights when you tickle his feet... or when I get a hug :-)
The Aniomagic touch-sensitive learning sensor can be calibrated to detect direct contact, or proximity to another person, so it made perfect sense to use it for this project. For this project, the tilt switch allows you recalibrate the sensor when you turn the robot upside down. Doing so makes him really excited.
- Robot patch from Instructables
- 3 sequins
- conductive thread
- large battery
- tilt switch
- learning sensor (touch)
You can grab the parts from our store, and make yourself a pocketable touch & hug sensitive robot patch.
Step 1: Preparation
The sequins fit this patch so well. Nothing else comes in such tiny ready-to-sew form.
The thin conductive thread is perfect for this project. It has enough resistance so you don't need extra resistors for the sequins. Just remember to double-stitch.
Also, look for this blue patch in your craft store. It gives you awesome grip for pushing and pulling needles through thick material.
Step 2: Lights
Step 3: Lights (2)
Step 4: Lights (3)
Because conductive thread tends to fray at the knots, experiment with starting your stitches a little distance from the holes on the learning sensor. Then work your way back to the hole, stitch well, and then move forward to the sequin. This way any unravelling won't cause shorts and touch other holes.
Step 5: Tilt Switch
For this project, the tilt switch allows you recalibrate the sensor when you turn the robot upside down.
Step 6: Battery Minus
This enables you to have a decent coil that will be taped to the battery later.
Stitch this thread, connecting the brass beads of the tilt switch, the "_" hole of the learning sensor, and to the brass beads of all three sequins.
Step 7: Touch Sensors
Step 8: Battery Plus
Step 9: Sealing the Battery
First, apply some tape to the minus thread as shown. This will help prevent short circuits with the battery "+". Wind the thread into a small coil and tape to the battery minus.
Step 10: Sealing the Battery (2)
The next project will feature a sewable pocket, but this will have to do for now. Now go git them hugs.
