A small cheap robot toy
Step 1: Tools and Parts
The tools needed to create BatteryBot
[Needle nose pliers]
Wire strippers/ Wire Cutters
Lighter or heat gun
The parts needed to create BatteryBot
 1.7volt LED
 9v battery lead
 9v battery
 330 ohm resistor
Heat shrink tubing
 (8mm) x 11/16 in length
 (4mm) x 3/4 in length
 (3mm) x 15/16 in length
Wiring Loom (3/8) x 1 in length
Step 2: Lay Out Components
Step 3: Find the Negative (cathode) Side of the LEDs
Mark the cathode of both LED's with a black sharpie. Mark it closer to the plastic lens in order to see it better later on.
Cathode: This is the short lead
Step 4: Shape 330 Ohm Resistor Into Suitable Head
Bend the resistor to fit the width of the large diameter (8mm)----11/16 in length of heat shrink tubing.
Step 5: Solder LED to Resistor
Hook the ends of the resistor and LED
Solder joint so the LED and resistor are straight in line
Bend the wire on the LED side for a tall head
Bend the wire on the resistor side for a short head
Step 6: Solder Second LED to Resistor
Repeat previous step for the other side
Optional: (trim excess of lead in order to keep the arms the same length)
Be sure that one side of the resistor has a negative LED lead soldered to it and the other side has a positive
Step 7: Prepare the Ends of the Led Leads
Measure the width of the head unit
Clip leads so they are in line with the width of the head
Make sure the leads are approximately the same length
Step 8: Prepare the Power Supply Unit Interface
Slide the small diameter (3mm)---1 in length of heat shrink tubing onto the leads
Step 9: DON'T FORGET !!
NO really, don't forget to slide the small diameter (3mm) ---1 in length of heat shrink tubing onto the leads
Step 10: Solder Battery Connector Leads to Components
be sure to have the black wire(-) connected to the negative (cathode) side of the one LED
This side was the one the WAS slightly shorter
It will be the side with the flattened spot on the plastic part of the LED
Solder the leads so they are straight in line with one another
Step 11: Solder the Positive Lead to Components
Be sure to double check that the connections have been properly made
Note: This might be a good time to check that the system works by attaching a power a source
(AKA: a battery).
Step 12: Apply Heat Shrink to the Robotic Arms
Position tubing to cover joints. A gap may be left near LED end for aesthetics
Use a lighter to shrink tubing
Make sure to keep the flame slightly away from work and move it in sideways towards tubing
Use the side of the flame rather than the tip to prevent blackening
Do it in small portions
Optional: Use a heat gun if available
Step 13: Create Head Unit
Tape the head by wrapping around one lead first and then around the whole head.
Press down on center.
Slide the 8mm heat shrink tubing unto the head and straighten any bent leads
GENTLY apply the heat shrink by heating with heat gun or lighter.
Do not shrink this one too much
Optional: Use arm mounted high energy disruptor beams if available
Step 14: Finishing the Arm Units
Using the (4mm) X 1/2 in heat shrink tubing create the arms
Slide tubes on close to body
Step 15: Create the Main Body
Wrap the power wires so they are approximately the same length as the (1) x 3/8 in piece of wire loom
No tape needed on loom
Step 16: Final Assembly
Install face by means of a black sharpie
Attach 9 volt power source
Optional: Use wire markers to create a face that you can reconfigure
We have a be nice policy.
