Hi! This is my first robot! I was waiting a week for electronic components to arrive from UK, and then long month to find proper chasis. I found it today! Not working remotely controlled crane on tracks. I have connected motors to Picaxe via motor driver as per "Start here" and tested the chasis, it works. Now my robot can drive in zigzags. Next step - get servo hooked up...

Continuing with construction I used an empty drugs tube to contain SRF05 and hook it on servo.

SRF05 and servo

This was qite easy to do with screews provided with servo from Picaxe servo upgrade pack.

After connecting all wiring project board secured to upper housing of ex-crane :)

Nice place for project board

And a hole made to make reprogramming a piece of cake :)

Now it is time to clean out my working environment :)

... and go back to code editor. First is "Start here" robot code updated to use SRF05.

Wow! My first robot is working now!

Next will be improving his navigation skills and... thinking what else he could do apart from avoiding obstacles :)

This is my last update on IsoBot. It's got some minor improvements like second power supply, which made him move a bit better and separate switches for both power supplies.

And the lastupgrade was a touch sensor in front of the robot.

This is it!

I set the status of this bot to complete as I'm not planning to do anything else to it. This was my first bot and I really enjoyed building him! But.... it's time to move to my next project which I already recieved some parts for!

 

PS.

I did not make new video as functionality did not change lot.

Nice head. I really like that little ladder on it.
Nice addition for the head! Very inventive. :P Keep up the great work.

Keep up the good work :)

You said your looking for things for it to do besides wandering around. One thing that is easier said than done is to try and make it find a docking station to recharge itself. Try adding a microphone and making it respond to sound.

That could be a good chalenge... Will look into this option. I like the idea :) Thnx!
Where and how do you guys get chassis?
I use sheets of HPDE (High Density Poly Ethelene) and cut is into part to glue together for the base. HPDE is very machineable (any thing that works with wood works even better with it) but not recomended for anything that will see high wear as it will "sand" away.
For me it was getting into each and every toy shop and askin for something with tracks :)

nice tracks! and a perfect platform for a first project!

keep it going  ;)

keep up the great work. Cant wait to see it all together!
