DTMF: Phone Controlled

This was a project bot from a workshop, a mobile controlled bot using frequency of the digits as a signals to function.  

It had simple frequency decoding chip for the mobile connected to it, and another transmitting chip to make the motors function. 

The concept was simple, make a phone call between the controlling phone and the phone attached to the bot, while the call is on, you can use the digits as control pad to the bot, which means it’s radio frequency signals went as far as the telecom signals.
The decoding board and the chip is available on robomart and with a simple relay system it can be attached to any bot(for high power motors etc).

The second bot(2013), this was actually a bot made as a difficulty arrangement in a inter school robo-war event organised by my team(an event of the student festival Comfest, visit www.comfest.org)
It’s a simple 4 x 4 motor bot(wired) with a rotating(controlled) flamethrower attached on the top using butane as its fuel, with improvisation later, it was made 6 motored(high torque) bot with bolts at front, the two chassis in the photo above were joined together for the purpose and same flamethrower concept.

My First Bot: The LEGO SPY Bot

This is where I started(2012), my first bot, the body is made of Lego mindstorm, made to balance on rear wheels due to attached wire, which held down the bot. The front wheels were of rear use, the bot maintained its position of pointing the camera upwards because of weights attached at the back and the wire itself. The mini camera is the attachable Sony PSP camera accessory, which works when directly connected to the console, an extension wire was developed by me to make it work on the robot as a camera, and the live footage was directly projected on the PSP screen which could be easily attached to the remote control of the bot. So basically it was a spy bot out of scratch.

The initial prototype, it all actually started with getting the PSP console camera work without fixing it to the console attached to a wire, like a gadget in old J. Bond movies but with a Lego kit handy it was made into a moving spy bot, the bot itself was very light in weight a small, with minimum pieces
