This is Bob, our 3 ft tall house robot using the Ez-Robot kit and leftovers from plastering angle beads (lengths of perferated coated- right angle tin use to finish edges of plasterboard).
The angle beads are super cheap, can be cut to any length and can be easily riveted together. The big plus is the material is super light but strong. Bobs head comprises of 2 X 1.25 ltr plastic bottles. We are soon to retrofit Bob with Electric drill motors so he can venture up the driveway and down the street.

That is great you are getting your son involved. I wish I would've been into this stuff when mine was younger. He's 19 now and thinks he KNOWS EVERYTHING!!!!!
Thanks Richie..look forward to those servo savers - and see you next week. Sfoy, in my family it's my 16 year old daughter Hannah that knows everything...lol
Really happy today - the Tank base arrived and Bob slotted on top as planned. The tanks acceleration is amazing. We had to shorten Bob about 8 cm to give him a lower center of gravity (he was too wobbly).
The tank has a plastic pellet firing turret giving Bob weapons capability - (totally not planned)and my son Austin can vouch for the fact they sting when fired at bare feet at close range. Our next mission is to see if the base can get Bob up to the letter box (maybe collect the mail) at the top of the driveway - it's steep and a real challenge.
Heres Bob perched on a 1/16 Toy Tank. OK on the positive side, it is powerful and has 2 speeds, it also has some form of suspension (causing Bob to rock forward and back during acceleration). Bob made it all the way up the steep driveway and back, an awesome accomplishment. On the down side, the radio transmitter that came with it is hungry for batteries (takes 8 AAs) and the range is poor. I'm looking forward to hacking it soon to rig up the H-bridge via the Ez-b with a toggle switch. One last thing is that these tanks are a little on the narrow side for Robots - apart from that, they pack a punch for moving from A to B.
Bob's looking great. Love the new treads.
That's pretty awesome, look at BOB go.....
He sounds pretty quite too. Awesome job....
