Let's Make Robots!


First steps again

My first steps in restarting my project was :

- Installing the Arduino IDE and trying to connect to my arduino board.
- Trying to figure out how the hell I connected the L298N driver to the arduino board :)
- offcourse writing everything down in a notebook

Next step is figuring out how I did the PWM on the L298N driver.
After that trying to reprogram my robot, since I lost the original source code, luckely for my it wasn't that big 

Pi Droid Alpha: New robot controller for the Raspberry Pi designed for education & makers

Pi Droid Alpha

Pi Droid Alpha is the best educational Robot Controller for the Raspberry Pi

I had a lot of great feedback from teachers on my RoboPi advanced robot controller for the Raspberry Pi, however most asked for a less powerful - and lower priced - alternative for simpler Robots. I listened :)

Wifi/Web controlled rover

I consolidated all of my Wifi/Web rover playing onto another chassis. I have the code mostly prettied up and should port easily to any Linux SBC. The code started on a Yun, touched-up and re-tooled on a PCDuino, then finally at home on an RPI!

I may post this bot here on LMR, but figured if anyone wanted to look at the code etc, they could.

Here is it on Instructables.

Gooseneck chassis wired for webing:

Building Scatolot MK IV

With 3d printed BaasWheels!
For offroad conquer!
Or awful slippage on flat surfaces

Needs to be fixed to the base somehow.

The Actobotics Warden

I have been sent a chassis to do a review on and will post one in the next few weeks. It comes from Robotzone/ServoCity and is called the Warden.

Motor ramping up and down

As of late, I had added some ramping to my motor driving code. I started with just ramping up but have added ramping down to stop as well now. Most hi-end motor controllers like the Sabertooth and RoboClaw do this for you, but it's nice to have on cheaper controllers to.

Greetings from Spain

Hi @all,

My name is Jose Luis "Josele" Perez. I live in Mijas, a village in Costa del Sol, Malaga, Spain. Mijas is close to Fuengirola and Marbella, the south of the sunny Spain

I got my degree in Physics, electronics, but I've been dealing with solders and electronic devices since I was a teenager... a few years ago haha! I still remember the old AC188K transistors ... a romantic dream nowadays !!

And my robot starts.

I have converted a Parallax BOE-Bot to run with an Arduino Pro Mini. It is my first step to converting an old electric wheelchair over to being a fully autonomous robot.

Found out that you have to modify the Board Of Education to program the Pro board in circuit.



project tracked byped

I'm working with a poppy robot platform as its complete parts list was easy to download and 3D print. I've decided not to use the dynamixel servos and instead made an adapter housing for standard hobby servos to be used. This is great for cost but it may bite me in the butt later as I now have limited support with my robot from the poppyrobot project group and must learn everything on my own. Blah blah Wha Wha. 


I became a member of Let's Make Robots a couple days ago.  That didn't last long.  I had been told what a helpful and friendly site this is.  That isn't the impression I got.  I replied to a post that I felt was giving bad advice.  I won't link to it.  It is easy enough to find if you like.I asked the poster, who is apparently a fourteen year old, to clarify their answer because I was afraid someone might damage their equipment following that advice.  the repsonse to that was basically that it was only a nine dollar board so who cared if they blew it up.

Real Life or Something Like It

i may have mentioned this in passing, but I'm divorcing my wife. I will file in the next couple of weeks. I could divorce her for cause but I'd rather do the simpler no-fault divorce because it will mean I can put this behind me much more quickly.

Unfortunately this means that I have to pack up all my stuff and anything I don't want gets sold or given away. I'm assuming it will take about three months to get the house in order before I can find a new place and unpack again.

Cheap 40W Laser Engraver from China

I have wanted a laser engraver for quite some time but the price has always been prohibitive for me. Recently though, I found some engravers from china on Amazon for about $500.00 USD and free shipping. Plus, I contacted the vendor and found that the unit would ship from California. I read all the reviews and they all agreed that the machine is great. However, the downside of these machines was the software that is included. After carefully considering all the relevant information I decided to purchase one.

It priiints!

Finally my 3drag prints after a whole brain operation, which involves using RAMPS, rewriting parts of the firmware, resoldering part of the arduino shield and drawing with a 3d pen missing and weak parts. Started october building it o.o

Little Back PI wagon reborn!

Well after a few starts, stops and redo's on the chassis, I have a new iteration of my Pi wagon. I have skipped publishing anything about the last two of three :)

MAKE: Skill Builder - Hydraultics for Robots

I wrote a quick tutorial covering some of the basic concepts of hydraulic systems, and how that applies to a simple robotic arm project. Read more on MAKE... 


Swarm Robots w/ extras

I'm thinking of trying a swarm robot project for sometime in the future. However, I want to do something different.

I'm thinking that individual swarm-bots might not be too intelligent, but what if each of them had a neural network, and with communication between bots, parts of the neural networks can combine (Holy Mighty Morphing Power Bots, Batman!) via radio.

Ridicule Page

Hi all,


I'm still working on my robot, however the mechanical side is almost complete, the electronics are almost complete, but the coding still remains to be finished.


Ready for the Zombie robot (or processes) Apocalypses

Had several laptop battery packs with 18650 in them. Opened the first two up and found 2.2mah Samsung and Sanyos. I have two more to open.  I'm sure the older one has lower rated batteries in it, but the other should be about the same as these. I plan to make one more 7.4v pack and one 11.1v and leave the rest for 18650 holders I have.

PI Bot, expanded

Here is some more pics of my Bot

Let's share our robots with the world! Follow Let's Make Robots in Social Media!

Hi folks!

It's being a while sharing projects and experiments together, developing out skills on robotics also having fun!

Marketplace at Let's Make Robots running well


Las week I purchased a propeller at the Let's Make Robots Marketplace and it works great. Here is the picture of what arrived, also a Pixter X Platform module board!

Lazy Sunday afternoon...

I had ordered a few things from ServoCity and was mucking around with them today and made this:

My Soft Robotic Hand in Popular Science

I'm really excited to announce that one of my robotics projects is now in Popular Science magazine!

I met two editors from PopSci last year at NY Maker Faire, and exchanged contact info. Later one of them reached out to me to ask if I'd like to do a robotics project for the magazine, based on the resources in Harvard's Soft Robotics Toolkit.The toolkit is an excellent place to start if you are interested in soft robotics.

I new bot chassis to play with. "Clamps"!

I After seeing the new Actobotics runt rovers and getting my hands on one, I find that I like them a lot for a quick inexpensive chassis.  Anyway, I have always loved boxy cars and was a Volvo owner for a long time. I had to have this one (Half Pint) since it's so, you know boxy! :)  Thinking of putting a gripper and a cam on it. Lot of room in the box!


Prom Night...Robot Style

Check out Anna rocking a dress...Artie is killing me with the bow tie.  Classic.   I'm just glad there are chaperones there...
