Looking for inexpensive web-based label printer

Hey Guys,

Slightly off the topic of robots, but I can't think of a better repository of smart problem solvers.

completely lost with rover 5 and dagu comotion shield

hi there,

I'm an app programmer trying to get into the hardware world. 

I bought myself an arduino uno a rover 5 2 motors and 2 encoders  and the comotion shield(https://robosavvy.com/store/dagu-commotion-motor-driver-shield.html)  hoping to be able to follow this tutorial :


I still can't figure which wires are for the encoders and which for the motors.

Am i being silly but I don't see it anywhere in the rover 5 manual~ :(

Full scale human torso on a hexapod, how to start planning?

Hey everyone!

I'm quite new to he scene. I am basically somewhat qualified in AI concepts and Programming, yet I totally lack any engineering skills. Would like to learn them en passant though.

So, what I am trying to build is a "true scale" human torso (well, basically a Spine, a Rib Cage [for Style reasons], a Head (cams and speaker), and sooner or later two arms (for budget reasons I'd like to add the arms later on, I'll just need to prepare the other parts so they can be added)).

most newbie person wants help with simplest project


New here but have a very specific project.

I essentially want a compact programmable servo.

i need a motor that will be able to hold a 400g load and be able to be programmed to oscillate at different degrees and frequencies.

eg 5deg at 1hz for 1 min then 25deg at 5hz etc etc.

a programmable chip so that i can program it via pc or smartphone prior to it doing the sequence would be ideal.

does this make sense?

i dont even know where to start with this. I am trying to invent something.

CNC kit recommendation?

Dear: LMR

Hey guys I really want to build a cnc. I have never owned or used a cnc and I have been doing a ton of research on them. Here's the thing I already have access to a cnc and am waiting to take a class on one. That cnc is at my makerspace. I want to build my own cnc for reasons that are primarily to learn how to build one and to kill some free time. But mostly to have fun. I don't want a massive cnc something that can fit on a desktop and that can most importantly engrave into soft stone like marble for artwork and such. Any recommendations? Thanks!!!

Get Rssi of RFBee with Arduino

I got Final Year Project to get RSSI value of RFBee with Arduino. But I don't know to do that because most tutorials show how to get RSSI value of Xbee. I notice that digital pin of Xbee is not same as RFBee. Thats make me more confuse how to do. I hope someone can show me how to get RSSI value of RFbee with Arduino. Thank you :)

Uart to Analog job


 I need this sensor https://www.robotshop.com/eu/en/benewake-tfmini-micro-lidar-module-12-m.html to output an analog AC voltage (any frequency, shape - sware, sine etc.).


 It needs a microcontroller, something that I need but unable to complete the task.


 So, I'm willing to pay a fee for the complete package.

 Any help is appreciated.


 Thank you,



Writing Boe-Bot Project

This year is my first year ever doing robotics or using Boe-Bots. My teacher assigned me this project where I have to somehow attach a writing utensil to the Boe-Bot and then when the teacher puts a word into the program the robot writes the word on a piece of paper.

Hello Everyone!

Can one Arduino resent serial com to another Arduino?


Can one Arduino receive serial communication via USB and then resent it to another Arduino via tx rx pins?


mbot line follower

Hi, i need help with my code. The mbot has to start and follow the line when i press A on my remote, while it's running it's suppose to show green lights. When mbot comes to the end of the line he is suppose to blink red lights. Red lights are suppose to blink 1 sec appart and blinking has to last in time of the mbot ride. So if ride was 12s, red blinking should be 12s and stop. With this code, everything works excpet red blinking goes on forever and never stops. Thanks!

Better Remote Control Options For Robotics Challenge


Sanity check and advice please.

We are entering a Robtics Challenge for schools which consists of a number of autonomous and remote controlled challenges. For remote control we are currently using a Pi Hut 2.4Ghz Wireless Game Controller:


We have a couple of issues with this method:


hello everybody
i want to move my servo 360 as sweep (from 0 to 360 and from 360 to 0)
i do it by servo 180 and it worked
but in 360 that not work!
pleas help me

Size of capacitor needed

I have a 18 VDC 5 AH battery with which I can charge a capcitor.  The Capacitor need to be able to discharge in 1/10 second at 18 VDC a 40 amp current across a 4.6 ohm resistance. How do I determine what size capacitor is needed?




accoustics and audio: hearing hardware for owl robot

Hi. I want to make an owl robot that has outstanding hearing...

Meaning it could hear a mouse at maybe 30 yrds or more.

The interaction device would have visual like the phone controlled drones do and also very high quality headphones so that the client can experience the hearing of an owl in the woods at night.

Any ideas on what sort of hardware to use?


Expedition vehicle - Auto leveling bed - motor and controller conundrum

As part of a van build project, I am including a system to adjust the height of each bed corner to a perfect level regardless of how the vehicle is parked. Adjustments will be made using lead screws that run the full height of the van walls. The mechanical portion of the design is solid including the necessary tolerances to support up to a 10 degree tilt in 3 dimensions. This is the optimal as the other purpose of the lead screws is to retract the bed into the ceiling when not in use.
