Satu hal yang benar-benar menarik perhatian kita untuk robot ini adalah penggunaan kreatif bahan yg mudah tersedia. Membuat tubuh, delapan kaki multi-jointed, ditambah dua hubungan multi-arah tambahan untuk mata kamera, bukan tugas sepele. Jika mereka terbuat dari logam atau bahkan plastik desain / prototipe lead time bisa sangat panjang. Dengan menggunakan sumpit kayu murah waktu pengembangan harus dipotong sebagian kecil dari waktu itu akan diambil dengan menggunakan bingkai logam.

The polymorph servo mount in the center of this leg piece slides along the chopsticks making it easier to get the servo in.
After some experimentation I now have one spider leg I am happy with. Just 7 more to be made :-)

I've made a simple spine consisting of 2 whole chopsticks joined by 4 sections of polymorph. Now I need to work out how to mount the Spider controller and the batteries. Once I have it walking I will add the head and mandibles.

Now that I have the robot powering up ok I can mount the battery and controller properly and tidy up the leg wiring. To begin with I need a frame to mount the PCBs on. Out come the chopsticks and polymorph.
Mounting the Frame was a bit tricky. The polymorph wanted to bond to the servos and the battery. I'm trying to keep this robot so that it can be easily disasembled for repairs which means NOT glueing everything together into one big lump.
After a bit of experimentation I got the high current switch mounted so thet the switch was easily accessible at the rear of the robot. The Spider controller is sitting high enough that the legs can fold up underneath.
After plugging in all the servos (24 for now) I tried to tidy up the cables a bit. I checked the weight. The robot is now 2.2Kg (4.85lb). At this point about 1/4 of that weight is polymorph. The rest is almost all servos and the battery. The chopstick weigh almost nothing.
Once I have the robot walking I can add the head and sensors.

You can see this ugly lump of diodes cable tied to the frame.I am waiting to hear back from the servo factory as to the voltage rating of these servos. I'm hoping they are rated at 7.2V so I can ditch the diodes and increase the power of the servos.
Now power
