Let's Make Robots!

auto trike

Navigate around via ultrasound

Originally this was going to be a bicycle light seeking robot, but what the heck it turned into an object avoiding trike lol. 

i still would like to make this a light seeking robot. if anyone has code for it.  

4 x aaa battery case

the wheels spin separately because when it used to turn the wheels tried to go in opposite directions causing it to skid.

the us-100 ping sensor i'm using can detect objects 3.5m away, but i have it set at 50cm

I like the minimalist design. Its very clean and looks like it works well. Nice camera work too!

Really nice how you made that work man. Looks like a trike for sure, cool fat tires, and simple common parts. Very creative!


I like the way it moves! Nice build.


WOW ! thats awesome ! ive been working on a project similar like this for a while now and ive never done it right ..... But you nailed it :)))


Great job!  Looks very nice and clean.  Good use of the battery holder.




Haha, that is a good idea. That trike needs only one motor, so only one pin is occupied. 

I like the choice of material and components, the Lego wheels and Popsicles are quite a common stuff here on LMR :-) excellent pictures and nice video. I am still missing some more deatils written about your robot,not that I can't imagine but I like to read them :-D
