Kobot Manufacturing

7 Kobots are flocking.

Yet to come!

No speed up in the videos! It is the actual speed of KOBOT but not maximum. For a detailed description of the obstacle avoidance algorithm p...

In the previous post , we have given the code segment running in the host microcontroller which requests and then receives sensor reading fr...

Short-range sensing system and the main control card passed the power-up test explained in the previous post, Yet another problem with short...

We faced a power-up problem in the short-range sensing system, actually in the PIC's. We have completed the sensor card, test it a littl...

Blue LED-PIC connection diagram The first problem we faced is in the blue LED of sensor 5 (sensor numbers start from 0, being the front sens...

Main control card is used to execute the main behavior algorithm of the KOBOT. It is 20x80mm in size and has a PIC16F877A microcontroller a...

In the short-range sensing system; there are eight infrared sensors 45 degrees apart. Each sensor has its own 12F683 microcontoller for maki...

Log for smd XTAL problem: - At first ECX-53B 20MHz XTAL is mounted with two 22pF capacitors. The pic is programmed but does not work. - Then...

First sensor is mounted and working properly. But some calibration is needed. There is not any problem with the range (~30 cm using 12x12cm ...

- PIC16F877A on the sensor board is mounted and first led test is OK! A problem occured with the 20MHz smd XTAL. It is solved by unmounting ...

A possible soldering order for the components of the power system: Flying capacitors on the bottom side of the power card: These components ...

The power card is soldered and seen on top of the sensor board. The critical components in the card is the two TPS60130 step-up converters, ...

We started building the Kobot from the power card. The power card is the main power source of Kobot's. It is 30X20mm in size and has tw...

We have just created the blog and started our mission...
