I have about 4 months to make a project but I have to give a presentation tomorrow about what I'm gonna do in the next 4 months so I need some ideas guys. I have decided on making a basic legged robot which avoids obstacles and since it's very short for 4 monts, I was wondering what else can I add to make it more complex ? I was thinking of adding a bluetooth module for controlling it via a laptop or smartphone and a gps module for coordinates or something .
Before you suggest anything , please bear in mind that I'm in India so I can only get some basic sensors and parts :/.
I have an arduino uno r3 .
So what can I do ? I really need some help :(
I’d use wheels if this is
I’d use wheels if this is your first robot. It can take longer to finish than you think.
For sensors I like the Dagu Compound Eye or the SparkFun smaller one that’s somewhat similar. IR sensors are small and don’t use much power, but they have a thin beam. Ultra Sonic sensors have a wider beam. I’m not sure a GPS will work indoors well.
You can have interaction with movement, body language, beeps, buzzes, and LEDs.
First welcome to LMR.Second,
First welcome to LMR.
Second, please check the rules about writing posts. Don’t get me wrong, i am not starting to yell now but I assume that you want to stay here even after your project is finished. We do have a couple if Indian guys here, so you will get a lot of tips from locals.
Now to your project. 4 months is short but can be long too. You are right, in 4 months you can do more than a legged robot avoiding obstacles.
Now I am starting my shameless self promotion 
Check my Chopstick Junior. I guess something like that would score a lot. Using common materials may be something what impresses your teacher and given your local supply chain it’s not far fetched to use what you can get in the best manner you can do. The Arduino Uno would also fit on a robot like that, you just need to modify the body to your needs. There are several “brothers” of Chopstick Junior and also his “Father”, don’t forget to check the origianal Chopstick which would be a bit too complex for a 4 months project but not impossible i guess.
most of the tech i use
most of the tech i use actually comes from China, shouldn’t be a problem to import in India.
Search on aliexpress for hcsr04 (ultrasonic sensor), to get a better location of sorroundings. For a starter bot it’s more important to not to crash on walls, than to get precise location.
GPS usually it’s expensive and works only outside, standing still and with a compass.
Don’t power servos from arduino, a wheeled robot may be easier to make, unless you already got some experience.
Beeps add lots of personality to robots, like wall-e or R2D2
Thank you guys! A lot of
Thank you guys! A lot of amazing ideas here :D! I’ll look into them and then decide what I’ll do :)!
Thank you so much!
