Do you think that the discourse site would benefit from some pictures of members personal robotic projects? I know that I enjoy seeing what other people are building, and sometimes it gives me ideas for my own builds.

I think pictures of any electronic projects would be good. I need to take pictures of mine.

Here is a link to a video, of my robot “Zoe”

Iocane - Do you have any close up shots of your robot?

The first picture was taken on Sunday and I have taken it apart since then to make more changes. Here are a few pictures of some of the major peices. For navigation it uses printed out sheets with letter combinations on them as navigation points for now. Unfortunately I couldn’t get the video of Zoe to play. Curious what the video shows. Thanks for showing the picture of Rex. Where did you buy the gears by the wheels? Maybe those are sprockets, I am not certain from the picture.

I really like your robot’s head. Is that foam? What kind of glue did you use on the head?
The wheels on my robot are from “Harbor Freight” - I think that they are “Go-Kart” wheels. They are not the highest quality, as the sprockets do not spin true.
It makes motion a bit loud. It has never thrown the chain though.
The motors are from “Silver Bomber Scooters”
The octagonal computer section holds a “car-computer” from Mini-box.com.
The computer section mounts atop the power section.

Side view of Zoe: shows motor, main wheels & chain drive. I call the aluminum frame the “drive section” - On top of the drive section is the wooden “Power Section”
[ This photo was taken at one of the RoBoMo Magellan events]
I recently added “on board speakers”…
… And covered them with a speaker grill.

The head is made out of EVA foam. I was looking around on the internet for ways to build the head and found that cosplayers were using EVA foam to make all sorts of complicated costumes like iron man or robot costumes. There are a good number of youtube videos with instructions on what can be done with EVA foam. It can be cut with a box knife. Shaped with sandpaper or a Dremel. It can be made to form to complicated shapes with a heat gun. I got some at Hobby Lobby. In the same section of the store was a strong low temp plastic for hand shaping called polymorph. There were also a sculpting clay foam, tools, and specialties paints to make the EVA foam look like just about any material. I used a glue gun and rubber cement to bond the pieces. Works real good on EVA foam. There is some sort of glue called barge cement which I have never tried that is recommended online.

My 2 front wheels are chain driven. The chain from the wheels goes to a smaller sprocket, on a “Jack Shaft” - The jack shaft is driven by a belt. The 2 belt pulleys and the motor came from “Silver Bomber Scooters” - The scooters were found by a robomo club member in a “recycling” center, and a bunch of us from robomo when there to buy a few. In my first design , I did not have the jack shafts supported by bearings on both ends. This worked, but the shaft would not stay straight, and it would throw the belt. So, I disassembled the drive section, and built bearing supports for both shafts. Here are some photos.

The drive section is built from 1 inch square aluminum tubing and 1/4 inch aluminum plates. I originally started with 1 inch STEEL tubes, but it was way too heavy.

I used the eva 5mm size. Its light but not like styrofoam. On the inside of the head I made it like I beams to make it stiff. I used the 12v motors used for powerwheels jeeps. Noisy but they work fine. Someday I will switch to something better. For now they work fine. There is a linear actuator on the piece on top that lifts a section up and down. This is for mounting a robot arm to so it has a better reach. I haven’t attached the arm to the new design yet. I need to build the part it will need to attach to. Plus it never folded out of the way before and that is something I am trying to figure out how to fix. Complicates navigation if a arm is just sticking out too much. Where is this recycling center where someone can get parts at? I could always use a new place to find supplies.

It was in an old abandoned school, in north saint louis. It has been several years since I was there. I couldn’t find it again if I tried.
We had to dig thru the stuff there - It was not open to the public - We had some “special deal” to search the place -

I added new links to the video , up above, on my original post.

If anyone curious my rebuilt robot now has 2 arms on it. They still need work. I made a changes to the base and made a lot of changes to the mechanism that lifts the arms. It’s turning into a whole new robot.

I am very interested in seeing photos of everyone’s projects. It inspires me to work on my own projects, and gives me new ideas. Please post some photos!
I have been working on a web page for my robot. I am trying to put my videos onto you-tube, because when the MP4 files are located on my web host, they “buffer” too much and are difficult to watch. You-tube has the ability to stream videos much faster than my shared GoDaddy host.
It’s not done yet (4-4-21) but it is located at My Robot “Zoe” : videos and build photos

There is my robot. Some of the parts are from the robot I last posted about here. The Darth Vader mask is over the previous head. Two arms, 4 wheels. It’s tall. The whole section the arms are on can move lower enabling the robot to reach low objects. I plan on putting some videos on YouTube. I like the robot Zoe web site. Lots of details

I like the darth vader head. You could mount cameras or sensors in the eyes or the mouth piece. Great Idea!
