X-Pod Quadruped Robot

Let's Make Robots Projects Showcase
1

Hello all!

Originally, I was building a biped walker with 4 DOF legs. I then turned the project around and started to build a quadruped robot.

Here is my progress.

I built my own battery recharging circuit using parts from Digikey + what I already had.
I bought 12 of HS-645MG from GreatHobbies.ca.
Everything else was purchased from RobotShop.ca, including sensors, Lynxmotion SES, batteries etc

List of electronics:
SSC-32
Basic Atom Pro 28
Dimension Engineering 3g 3-axis Accelerometer
PING)) Sensor
PS2 Wireless Controller

Things to do:
Clearn up wiring
Adjust servo offsets
Lots of programming :slight_smile:

EDIT: I couldn’t get the image to show on this post for some reason, so I just pasted the link :confused:

PS: More detailed progress is posted on my blog, but I don’t have anything amazing to show… not yet 8)

Hi,

Looks like a fun project, great work!
What did you use as a base for the body, a SES aluminium channel?

Thank you! I am having lots of fun working on my project :smiley:

Yes :smiley: You got it!

It looks like you may have painted the lexan parts. You know the coating peels off right? It’s detailed in this tutorial. lynxmotion.com/images/html/infolexa.htm

Clever design! I love it!!!

Looks like you did forget to peel off the plastic cover. An exacto blade or the corner of a razor blade is what you need to get under the covering, once you have a grip-able piece lifted up, it pulls right off.

Nay, I had no idea :blush:

@SN96 Thanks for the pointer, I will get er done!

EDIT: I just peeled off one of the leg and wow it looks fantastic! Way better than my poor paint job :laughing:

nice, good to see another quadruped project. takes me back when i had mine.
any reason for mounting the coxa servos upside down? not that it matters.

8

Perhaps to have the servo wires on the top rather than the bottom. I love the design, the more I look at it the more I like it. Great work.

Slowly making progress, I have been kept busy with some stuff lately :neutral_face:
Struggled with timer interrupts for a while because it kept interrupting serial communication making the robot twitch and jerk. (although it was sort of entertaining to watch :laughing: ). I am trying various approaches in terms of programming.

Here’s a vid.

Edit:
Forgot to mention, I bought 25ft of cable wrapper, as soon as it arrives i plan to remove one of the battery pack and flip the ssc-32 upside down so it looks cleaner. Also, I realized that there is a difficulty at initial start up standing procedure due to short C brackets limiting the range of servo movement and having long legs didn’t exactly help. Not sure how to improve this as of yet, other than having to purchase 4 sets of long C brackets.

Very cool. Looks like the progress is steady. Keep us updated! :smiley:

I have a question about what SES channel you used for the body? was it the ASB503? or the ASB504?
