The Strandbot is a DIY upgrade for the Strandbeest originally designed by Theo Jansen.  Strandbeests are amazing mechanical creatures that are able to move on their own using just a little bit of wind power.  Unfortunately my tiny apartment is short on wind, so I decided to upgrade a miniature Strandbeest using an Arduino and some motors.  The brain is powered by a solar-charged Li-Po battery so the Strandbot will live on as long as it can find some sunlight.  The motors are remote controlled using an Apple Remote, or with a tiny bit of coding you can make it work with just about any IR remote transmitting at 38 kHz.

The Strandbot can be built in about 30 minutes and requires the following ingredients:

1 Strandbeest, split in half (http://tinyurl.com/7qqs8op)
1 Strandbot body (http://shpws.me/ohXz)
2 Drive shaft couplers (http://shpws.me/oufQ)
1 Tamiya Dual Motor Gear Box (http://tinyurl.com/mp9gzcq)
1 Arduino Uno R3 (http://tinyurl.com/q3zteg6)
1 GROVE Base Shield v1.3 (http://tinyurl.com/ok4k2zo)
1 GROVE LiPo Rider Pro (http://tinyurl.com/pwwxba2)
1 GROVE i2c Motor Driver (http://tinyurl.com/q4jospz)
1 GROVE Infrared Receiver (http://tinyurl.com/qf5tjtl)
2 GROVE cables (5 cm) (http://tinyurl.com/lxz8cwl)
1 Solar Panel (0.5 W measuring 55x70 cm) (http://tinyurl.com/pdjksu9)
1 LiPo Battery Pack (3 Ahr at 3.7V) (http://tinyurl.com/pysmpml)
1 Battery (9 V)
1 Battery terminal with +/- leads
3 M3 x 6 mm nylon spacers
3 M3 x 6 mm nylon machine screws
4 M2.6 x 10 mm machine screws with nuts
4 M2 x 10 mm machine screws with washers and nuts
2 M2 x 5 mm machine screws
6 pieces of aluminum wire (100 mm length x 2 mm diameter)
1 USB cable (A to B, 15 cm length)
1 Apple remote

Step 1: Prepare the GROVE Base Shield

The GROVE Base shield makes it very easy to connect the i2c Motor Driver and Infrared Receiver to your Arduino with no soldering or messy wires.  It also makes it VERY easy to add functionality to your Strandbot by simply connecting any of the plug & play GROVE modules, even after your Stranbot is fully built.

The basic shield requires slight modification before mounting to the Strandbot body.  Remove the three 3M nylon machine screws securing the transparent cover plate and replace them with threaded 6 mm nylon spacers.

Then, connect one GROVE cable to the first I2C connector of the base shield.

Next, connect the other GROVE cable to the A1 connector of the base shield.
This is really cool. Always loved the strandbeest design and this makes it more fun.
Thanks! The strandbeest is such a great platform. Working on another project now to replace the Arduino brain with a 'real' brain in the form of a cultured neural network (cue mad scientist laugh).
I adore the Strandbeests and this 'ible just nails it! <br>Voted! :)
Thanks for the vote!
<p>Hi garriaga. Great project! I'm gathering all the pieces in preparation for putting it all together. I know you have the Strandbot body and the Drive shaft couplers on shapeways for ordering, which is nice. thanks for that. but I actually have my own printer and my school project, that I'm making this for, is due sooner than I can wait for shapeways to come through. I'm also trying to cut down on costs. Do you have the .stl files for those parts up anywhere where I can purchase them from you? I would greatly appreciate it.</p>
<p>I have all the supplies except the 3D printed strand beast , May I know where did you get the .stl files for the print. Also I planning to use Raspberry Pi instead of arduino</p>
<p>Do you know of a way you can track the amount of solar power you have at any given time?</p>

Or the money for the supplies
Although I can't make it : (
Of course you can make it! Links to all the materials are provided and it is designed to be a pretty straightforward build. Let me know if you have any questions or doubts to why you wouldn't be able to do it. Have fun &amp; good luck!
I can't make becauseI don't have supplies<br>
