Humanoid Biped Pete

Lynxmotion Legged Robots

I would like to build the Humanoid Biped Pete. Since Lynxmotion doesn’t sell a kit for building the Humanoid Biped Pete, I want to make sure that I order all the parts that I need for building the Humanoid Biped Pete.

Here’s the list of parts:

1 - Humanoid Biped Torso - BT-01
7 - Multi-Purpose Servo Bracket - ASB-04
6 - “C” Servo Bracket - ASB-09
1 - Offset Servo Bracket - ASB-11
1 - “L” Servo Bracket - ASB-06
1 - Robot Foot (Pair) - ARF-01B
1 - Servo Hinge - PSH-04

Either:

2 Robot Hand - A Single

or:

2 - Aluminum Tubing - 3.0" - AT-02
1 - Aluminum Tubing Connector Hub - HUB-08
1 - Rubber End Cap - REC-06

I already have servos, Arduino boards, and batteries.

Cost with hands - $254.65
Cost with tubing - $234.15

Do I need anything else?

You will need a control board for all the servos, a microcontroller for the logic, ba battery and a distance sensor if you want to make it a bit autonomous:

Do the “Humanoid Biped Torso” and “Robot Hand - A Single” kits have servo hinges? There are no part lists in the assembly guides for these kits.

My biped robot project has 22 standard servos. Programs for robots like RoboPhilo have fine-tuning tab for servos. I’m using Dagu Spider Robot Controller based on Arduino Meta 1280 board. Is it possible for me to create code that lets me fine-tune servos?

I had to make a plastic part that allows me to mount the Dagu Spider Robot Controller on the robot’s back the same way that the SSC-32 board is mounted on the robot’s back. The screws that hold the ball bearings to servo brackets should be turned around to clear the servo bottoms.

What would the objective of “fine tuning” the servos be? First step is always to try to mount the servos to the brackets as exactly as possible, then add offsets to the code.
