ZBot
Non Existent Projects?
After months and days of searching I cant find any websites that are developing a hobby based phased array soultion for robots or whatever, so I am very very tempted to get to work on this straight away when I move in, rather than spending time on my robot like I had planned. Also, another [...]
Quick Zbot IR note
I could mount the IR and the IR rx on the top and bottom of the boards, then I wouldnt have to worry about them interfering with each other! Cant believe I didnt think of that before! Might not fit with the wiskers on though?
Also, I could add some transistors to make the power output [...]
Quick thoughts on the Ultrasonic Phased Array Project
Just been doing some bored research again, and I came accross this image:
This would be a good route to investigate when I do get it up and running. I Could initially scan for objects, then focus in using this technique. First seen here but there must be other sources out there. Hence, [...]
Next Things to do for the ZBot
Well after a long period where I had no access to my electronic equipment, the time is nearly upon me to get it all back out (just in time for the christmas holidays!). Heres what I need to do:
Go over the IR code and change/rewrite if nessecary
Change the IR diodes to radial types
Hot Melt [...]

First Incarnation of the ZBot
Well Ive spent today getting a simple bot going, and its working ok(ish) on the breadboard, so Im now going to transfer the IR’s to stripboard and then the rest of the bot to something.
ZBot IR
Got the 2 IR working. Bit of a pain in the bum in the fact that its, once again, not mega reliable with triggors at random moments and sensitivity to flourecent lights and sunlight etc.
Now Im going to get the motor working like before with the following circuit:
taken from here.
The code is already written in [...]
Downgrading ZBot
Well Ive just about finished my Thesis, so I will have a bit of time to start the ZBot again. Decided that Im going to forget the I2C because its a bit too big. I could do it, but I dont really have the time.So I’ll spend one weekend getting a full 2 IR LED [...]
