Omnibot Modernization

Now that you have your new drive tray and new servo arms in place, you need a controller and remote. You could use a commercial RC hobby controller that has the ability to mix mecanum wheels. However, depending on your goals, you might miss out on some expandable options that can really only be done with a microcontroller such as controlling screens (as in the Omnibot Eyes project - yet to come).

So, by now, we all know that social media creates "echo chambers" or news and social feeds that can reinforce extreme views and beliefs.

How does this happen though? What is the algorithm doing? Are you sure you want to know?

Omnibot Modernization

The Omnibot back in the day was a marvel but certainly had some interesting limitations. One item that they seemed to design as an after thought was the little round eyes. They were simple light bulbs that took a note from every other Spensor gift of the era - they flashed to the sounds that it made. Cool enough but hardly cutting edge even at that time.

Fast forward to now and even cheap toys have more impressive effects. I'd like for Omnibot to be able to express emotions with its eyes like you see in Wall-E or with the very cool Cosmo or While we're upgrading the existing functionality, why don't we improve on the expressiveness of our favorite little bot by replacing those light bulbs with LCD screens!

Omnibot Modernization

The factory drive for the Omnibot 5402 and Sr use two sets of wheels that are driven by two motors - one per side. This gives the Omnibot skid steering like a tank. It can turn in its own footprint and move forward and backward but not side to side (called strafing). For this project, I want to change out the original drive and wheels with 4 mecanum wheels each with its own drive motor. This will of course require new motor drivers since the original electronics aren't used.

Omnibot Modernization

As a kid I dreamed of getting one of the Omnibots from RadioShack! Each Christmas and birthday I would beg and bargain for one but to no avail. They were too expensive for a toy, my parents would say. I dreamed of "programming" it to do all kinds of things little knowing that my parents were right. As cool as they were, Omnibots just weren't as useful as the advertising and my imagination made them. Little did I know that they couldn't even move their arms! Let's fix that!

In this project, we'll walk through installing the mounts and making the necessary modifications to the arms of your Omnibot 5402 or Sr for motor control of the arms. My goal was to create a structure to move the arms by the shoulder with minimal modification to the bot itself. It will still require two parts being permanently modified but it could still be reverted back to a cosmetically but not functionally original state.

I'm really terrible at this whole blogging thing. 😕

Anyway, a lot and a little has been going on since my last home automation project overview. I have been really busy with odds and ends over the last year and a half although, only a little has been spent in any meaningful additions to my sub projects - save one!

How has this past year been for you? Stressful? Lonely? Maybe a bit of hopelessness?
Now that the vaccines are being distributed, are you feeling a bit more optimistic?
It has been over a year since our society went home to our bubbles of isolation but for people with disabilities or other limiting factors, the pandemic was just more of the same.

Have you ever had one seemingly trivial issue open up a torrent of "opportunity" and possibly may have saved your life? I believe we may have.

So, I have two years of projects and ideas behind me. With all of the fits and starts, labored undertakings and successes and failures, what does the next year hold?
