Phoenix alike hexapod "DarkSkitter"

Dear all,

My name is Sam from Penang, Malaysia. I’m going to introduce my Phoenix hexapod “DarkSkitter” which I’ve worked for many days. Firstly, I’m going say Thank You to Zenta who is the Phoenix founder and Xan “BlackWido”. I’m totally ZERO on mechanical and electronic but this 2 hexapod ( Phoenix & BlackWido ) given me strength to build one myself. Xan had given me a lot of advice ( Thanks Xan ). Until now I’ve finished the mechanical part, now I’m facing problem on the software part especially the IK theory which are going to apply in the programming. Of course about the calibration also I haven’t make myself clear. I just broke a servo horn last 2 days. Xan had advice me to put my thread here so that I can learn more. Hope that if anyone here can give comments and guidance to me. Thanks!

Here is my Phoenix - DarkSkitter photos.

Hi Sam,

Nice job! :slight_smile: ; your bot looks nice, especially the robustness and compactness of the mechanical design.

I have started building a similar bot as well (“yes” with the assistance from Zenta and Xan :slight_smile: ) and my bot is now waiting for the inputs. Mechanical part is done and its time to play with the sequencer now. So, i believe we’d have a good learning time together since our problems are the same :slight_smile:. here’s the link to my thread, see if you can find some info to start.

The very first step in this regard is to determine the center, min and max positions for each servo through SEQ, read Zenta’s PEP manual along with the spread sheet again and again to build some understanding and eventually start building simple movements through SEQ. This is the work flow, I have thought to start with.

Looking forward to see your updates. You would get a lot of assistance to start with this bot. “I TRUST this forum”

Thanks :slight_smile:

Hi Sam,

Good to see you on the forum! Welcome! There are a lot people around here that know much more from robotics that I do and they are always willing to help.

I think that you are doing well and already made some good progress! You are just a few steps behind on Umar so you will both encounter the same problems.

I completely agree on Umar. I think that it is a good idea to start reading and understanding Zenta’s manual and PEP. This is a great resource for your IK. It is not possible to simple drop in the code and start walking. Even if you have excactly the same hardware it is tricky becase of the servo offsets and min and max angles. :unamused:

When you want to start programming, start simple. Try to move some servos, implement FK and when the PEP gets more clearly. Try to implement 2DOF IK. When you’ve got this working, you really made a lot op progress!! 8)

Keep us posted!

Nice to see a roboteer from Malaysia~! (I’m from Msia too)

Robotic here is expensive, how you plan to work out your electronics? Unless you have enough to fork out several hundred for SSC-32, I’m guess you intend to build the electronics from scratch.

PEP is designed for SSC-32. Unless you purchase that, you can only use it as a reference.

Several hundred? Why not just have one shipped from the US?

Several hundred Ringgit I guess :wink:
(1 Malaysian ringgit = 0.298686 U.S. dollars)

Hi tnay, glad to hear that you are from Malaysia. Which state are you from? I’m from Penang. Ya, in Malaysia robotics are very expensive but when I saw Zenta - Phoenix & Xan - BlackWido then both of their bot convince me to make one myself because I really can’t believe that the gait (movement) can be done by using IK method, I feel that really a MAGICAL movement. Its make me fall in love into learning on how to actually make it works like that, so I started my journey!

The SSC-32 is not expensive but the shipping is expensive but finally I bought one also. The servo motor I use MG995, one for 55 ringgit Malaysia because Hitec servo motor is too expensive in Malaysia and is about 140 one in ringgit Malaysia. You can get the MG995 servo motor from a shop name Bestens Sdn. Bhd. under the brand BVKits.
bvkits.com from Penang & the mechanical parts I build it with steel.
Lynxmotion won’t accept credit card from Malaysia so I have no choice and have to find Lynxmotion distributor which is Roboshop from Canada. That’s how I started! :laughing:

Hi pyrrhicpk,
I’m still a distance from you & still need your advice. Now still struggling on the PEP & of course the IK theory.
