Description

My quadruped is a 3D printable robot that will be upgradable to an unlimited amount of legs (as long as you have the electronics to control it) I wanted a robot that I could build expand when I wanted I am currently getting this robot printed by a friend I have had low quality parts made quickly to test fit certain parts. I will control the quadruped with lynxmotions BotBoarduino and the SSC-32 Servo Controller (mounting brackets to come) with Bluetooth control and ps3 controler with 12 tower pro sg5010 servos to start with due to cost but will upgrade servos to something better please bare with me I will supply instruction soon as I make it. i am working on the extra leg version now will post them soon as well as other add ons.

Everything has been designed to be printed on a standard print bed.

Pictures will be added as soon as the servos decide to turn up .

remember I have made this for you to make so don't be afraid to ask for changes Constructive criticism very welcome (but don't abuse it)

Do you have a photo of a finished product?

The Spider Controller will handle 48 standard servos as well. You just can't POWER them all from the board. If you connect the servos to a separate power source, and the signal line to the Spider Controller, you will be fine. As was mentioned already, keep on eye on the current required to supply to all the servos and plan accordingly. A couple/few UBECs should do it depending on how many legs you are going for (look for the ones that can switch to 6v to get the most power to your servos). I'll leave a link to more information, you can catch the designer here from time to time if you have more questions about it. :) http://letsmakerobots.com/node...

Hey there, just thought I'd clarify some stuff about that board. The reason that it says 48 micro servos is because it has a 3A MAX current limit on the board. I'm not sure what the stall current is on your Tower Pro's, but most standard sized servos have a stall current of about 1-1.5A. This means that if say, the first two legs got stuck and drew 2 amps, plus the current of the other servos, it could break your board. The SSC-32 is rated for 30A and is more than capable. If you are looking for a slightly cheaper board that can be daisy-chained easily, you might want to check out the Pololu Mini-Maestro's. They have a nifty computer application for controlling them too.
Also, nice project! I really wish I had a 3D printer so I could try it!

Instructions

OK here goes bear with me this is my first time with instructions like this so i will break it down into segments.

1. the feet are made up of 5 sections each 2x foot sides, 1x foot support short, 1 foot support long and 1x toe look at the foot picture for guidance. my plan was to use an m2 tap and m2x8 countersunk screws to make it look nice and neat but you can use self tappers you may need to drill the holes a bit bigger to avoid splitting. im planning on using the toes with pressure sensors mounted in the feet to allow it to feel but for now it will be fixed.

2. the Femur/legs made up of 3 parts 1x leg and 2x pin there may be another part to the pin soon a sort of cap that screws on just need servos to turn up to make sure sizes are right i may even get rid of the pin a print the leg as one piece the pins fix onto the leg in-line with the servo horn to act as a pivot see the leg assembled picture.

OK got to go to work now will finish this later

This board may be better for this bot:

thanks i have never come across this board before it says it can control 48 micro servos do you know how many normal servos it will handle?

This is worth "liking" if only for its name! Great.

Does anyone have any arduino code to test control one leg with 3 servos to simulate walking?
