This is a bottom plate, which will support the
battery. The battery, as before is made out of two cell phone 3.6V
NiMH rechargeable batteries. |
 |
Everything ready to connect with the small screws. The
PCB is a part of the construction. |
 |
PCB and two elements of suspension
connected together. |
 |
And it is time for the bottom plate... |
 |
Now it look like a tank! Cool! |
 |
Side view... |

Back view... |
 |
Front view! |

The IC sockets are not soldered yet but they give an idea
how we are going to build the circuit. In the first approach it will
be the MCU (Main Control Unit) built using PIC microcontroller, but later
this PCB will be controlling the stepper motors only and will serve as a
power supply with +5V stabilizer. As MCU we are going to use another
PIC microcontroller on another PCB installed on top of this one. |

The motor sprocket and the chain zoom! |
 |
Here comes the problem. Too small distance from
bottom of the suspension plate and the ground smells like a
trouble. Looks like the sprockets are too wide and the side plate
can give us problems during clearing the obstacles. We'll see... |
