Micro controller and H-bridge testing

Back from EID...............

It was a gud whole weak of holidays. Now we are back to work. First thing we have to submit is project purposal defence. We have completed one shaft of simba. We have devided our work domains.

Shafts and Wheels

We have completed one shaft and wheel also. Pics are here

Maxon Motors

Slightly changing of plan, we are now using maxon motors with maxon gear head. It has torque as well as speed.....................

...Aesthetically, we want GR-simba to look like this.

PROJECT HEADS

Sir Shamyl bin Mansoor will be our Adviser and Sir Habeel Ahmed along with Sir Abid Mushtaq will be our Co-Advisers for the project "GR-SIMBA".

lahore trip

We are going to lahore on saturday to buy motors from Bilalgunj.

Our trip was great. We bought two PITMAN Motors. These are geared motors, maximum operating voltage is 24 V.

We have also bought a battery of 12V and besides that we have bought gears of different sizes along with chain and alluminium sheets.

We have decided to go for 24inchesx18inches design. And wheel size for maximum tarque should be of 6cm radius.

meeting

We are going to hold a group meeting in which we will discuss our mechanical design. I hope it will go well!
