Thanks ^^

Sounds like you need a distance sensor; infrared or ultrasonic. If the sensor is really small, then infrared or laser (expensive).

hey can anyone tell me what censor i can use to find out distance between those censors…
for instance, i m going to use 3 sensor… A B C and i want the exact distnace between them and send it to something like central hub … motherboard or something…
what sensor will do the job…??

Take a look at the article: how to make a simple beetle robot, and add a solar panel to charge the batteries. You only really need two motors.

Hey …
Frnds I want to make robot working wid d help of 12 v solar panel and bettery charger … Which can scence object and turn to the left or ri8 which is nearer clear way … How can I connect solar panal btry and 4 motors. ??? Can u plz reply soon …

That’s more of a design question - can you contact us via the RobotShop Forum and perhaps include an image of the setup?

Thesis Project- There are cabinetes/ boxes said- Universal contacting modules.
The two marks are on the mudole and inside it. I need to find the exact position of these two marks so as to localize the Motomann to these points if interests.
Which sensor is applicable and cheaper and easy in realization ?

“Thesis” = master’s thesis? Creating a functional solar powered lawn mower is quite an undertaking. 1) create a very lightweight, custom mobile platform; 2WD and 2 casters 2) Add sensors to avoid obstacles and stay within a boundary 3) add a solar panel either directly on the robot, or on a docking station 4) add a motor and blades to cut the grass.

very nice tutorial…
but i really dont know how to start our project thesis in our school…
we are asked to make an automated lawn mower using solar panel…
can u guide me?
making a solar panelled device is easier,
but making an automatic device is much harder,i think…
thanks and god bless…!

Hi its very nice tutorial, i got many required things form this tutorial thanks to post such terrific tutorial

I need to use an appropriate sensor for the distance measurement , to develop the control algorithm which makes two robots follow each other at the certain distance, at moment, ultrasonic sensor does not work properly. Putting a surface in front of the sensor doesn’t show any significant changes in distance measurement ( I have tried black and White A4 papers. Which sensor do you think I can apply in term of accuracy and cost?

heeee its so teerific
please publisshed next episod
bcz my robotics event coming soon
so its goigin to helpfull me

it’s very nice

These sort of announcements go better in our forum: https://www.robotshop.com/forum/

Sorry about the comment spam; this certainly isn’t the right place for this, but I couldn’t find a contact page on your blog.

I’m not exactly sure who to contact within your organization, but a few helpful people on reddit recommended robotshop as a way to get the word out about our “Securing the Future” program.

We (security-camera-warehouse.com) are currently giving away security cameras (single camera, up to $150 in value) for use by US-based academic institution, school robotics teams, non-profit organizaitons dedicated to youth science education, or other science-education themed teams (such as club level robotics teams).

Would your readers be interested in this?
