Humanoid Project – Review

David Offerman — Mon, 13 Apr 2009 15:25:17 +0000

This is a review of what I have so far on the Humanoid Project.

Specs:

Roboduino MCU

2x HS-311 Servos

2x Wheels

5x 9g mini Servo’s

Wood, Plastic, screws, bolts and nuts

Start

I started this with just the sides, top and had the 2 HS-311 drive servos on the side. That didn’t do much so I had to keep on building, I built the front and bottom. Since my robot couldn’t balance I added a 3rd wheel to the back from my Offy Bot robot.

Moving

I set up controls for my robot to move using W A S D or the basic gaming keyboard controls. Since that wasn’t fun enough, I coded a program so I could use my joystick to drive it, I set my justsick axis to those letters so I could drive it around.

The Arms

I cut 2 more holes, one on each side, for the arms. The arms can go up and down using the servo atttached to the chassis, than it can turn side to side by the servo attached to the servo that moves up and down.

As you can see, the arms do not touch the ground, and the ends of the arms are angled at 45 degrees. They are angled at 45 degrees so they can touch each other so it can pick up what it needs to. They don’t touch the ground because it would have hit the wheels, the ground and much more and would of caused to many problems.

What is going to be added

I am adding bluetooth so it will be wireless. I am also adding a spy camera for the eye’s the data will than be sent to my computer, a program will process what is going on, and send it back to the robot. Sonar is another thing I will be adding. I will have 2 ultrasonic range finders on each side of the head acting like ears. I will than have a program on my robot so if it sense something coming closer and closer, on the program the side it senses the movement will blink, so I can look at it. The last thing I plan on adding is voice. This will be done using Wave Shield and a old computer speaker that I take apart.

Autonomous

This is when the robot can think on its own. As of right now it is all manual controlled and I am not a big fan of that. Once I get all my parts such as the vision, bluetooth, range finders I will set it up to be autonomous also. It will be autonomous when there is no serial connecction, serial connection is wired or wireless from my computer to the robot, so if I don’t connect to my robot, and it has power, it will think on its own.
