Mower and BBG/MotorBridgeCape

I am trying to make a robotic mower for the BBG and MotorBridgeCape with some old parts, electronics, and/or stuff...enjoy.

Similar projects worth following
Making and baking! As you can tell on the photos, I have a long way to go. I still need to change out the software to make it suit my needs. I also need to assemble the components but the holes are drilled and the motor for the blade works again (YES).

So, I will attempt and attempt again. I will do this to ensure my project gets completed one day.


P.S. I have the engine, motors, and wheels. Assembly is easy. I will have to wait to keep hacking the code to change it. One issue is there is not a radio yet. I will probably set up a HTML and server instead. Okay...back to work!


I got this sucker to go and stop and go again. Good things come in odd packages.


P.S. If you are working with the Motor Bridge Cape, let me know. I sure could use some Python software advice.

straight, turn, back to where I came from, turn, and repeat...

Working w/ DC motors...this is a Python file that goes in the same directory as the file. This software only controls one motor.

  • 2 × Wheels I just got some new, with tube, wheels to conquer heavier terrain.
  • 1 × BeagleBone Green Linux Computer for hacking.
  • 1 × Weed-eater Engine Red Max
  • 1 × MotorBridgeCape for the BBG Add-on Cape for the BBG/for motor support with a power supply.
  • 2 × Motors These are for making the the moved move.

    I just configured the, and yes this has taken forever and a day, web application to work w/ the BBGW and the Motor Bridge Cape w/ the help of and a person on #beagle on Freenode.


    I will promote this web application soon w/ Flask, Bootstrap, and HTML on


    I have to set up git on my BBGW and then update the software on the page.


    P.S. If you are more interested in this concoction of ideas, please contact me or wait longer to see what transpires. 

  • Dude! Bro! Geaux!

    I got this thing put together and it can geaux. I am currently working with Flask, Python, BBG, and the Motor Bridge Cape from Seeed Studio to make this sucker hum.

    I want to be able to write an application with Flask to make my motors understand what it is they need to know to geaux but geaux more than just geaux. So, I have to make a separate understanding on my behalf in the form of education.

    I was thinking. I guess I could make a motor provide enough current to make the battery recharge but I am far away from this progress. Enjoy!


    P.S. If you have any ideas, please let me know about your usage with Flask, Python, and HTML. I like to work with this dated yet useful packages/languages. Yea boy!

    I have been out of the funds to support my project. So, in hindsight, what I did was so worth it. I got a credit card, maxed it out, and went for broke. Now, I must pay some handsome interest. Boo! Anyway, this is the part that was worth it.

    I got my parts, my software still needs work, and I can now say I am a part to the human dilemma of debt.

    If you have any questions on the software, the Motor Bridge Cape, and/or anything in between, let me know. I have been working on this item for some time now and I have just about every quirk worked out.


    P.S. I can run four motors off the Motor Bridge Cape with the correct software. What is listed is only for one motor and that software for the file needs to be altered to suit the needs of specific Debian-Linux distros. Let me know!

    • Drilling into Stainless, although it weighs more and is heavier than "Butter" aluminum, is a pain in the A$%.
      • I have been making mistake after mistake since I lack a drill press.
      • So, with these mistakes showing up, I have to consider the damage and reconfigure.
    • I have all the equipment so far.
      • All equipment is ready to be assembled except for the drilling of the stainless steel that will house my two motors and weed-eater engine for propelling the blade to cut.
      • Once the stainless is drilled, I can add my other electric DC motor to create a triangle of wheels. Two motors will carry sprockets as wheels for grass interference and there will be one swivel wheel in the front to create extra support.

    • the meantime is when I can alter this software to suit my needs. I may need assistance in the software field but I will let people know soon.
    • If you get bored and you are reading this info, please try to contact me with any questions or concerns.

    This is the "finished product" for now. I still need to cut some long spindle shaft and reattach it somehow, e.g. with the least vibration. I do not need a bouncing mower, i.e. just a Geaux Mower!

Enjoy this project?

I came across one issue. My shaft that spins to make the blade turn has two spindles, i.e. one on each end. The issue is that I am going to cut this at some point to make the length shorter. I only have about 12" to 18" to work with...

So, how in the hell am I supposed to attach these two sides, the sides of the spindles, together to get a smooth rotation of my blade? Heh? I know it is some mechanical engineering marvel but I just am going boinkers over this issue. Anyway, I will keep people updated.

I think this idea works for now. I got two motors, a BBG, a Motor Bridge Cape, and some software. The build was not all my doing. I had help with the first start of the software from Seeed and their Wiki and the metal components are cut, drilled, and done all with some machine that I do not work on.

Yea boy!


P.S. I will post a video as soon as I figure out how.

I am just getting used to working with robotics more. So, sit back and enjoy the lower level expertise of me using electronics.
