Spider

Yes, it somewhat looks a spider with 6 legs (:P) and I believe it scares the real spiders and even bugs LOL.

Update: 17-01-2018

design drawing, yes it’s not perfect and please excuse for this.  spider idea

A small hexapod with copper legs and HS-311 actuators/servo’s, I have used 3mm thick copper wire for legs, I had no better option at the of making So I did go with the things I have and a sheild wire, copper wire and paper tape to attach the 3 servo’s

With bending tools I was able to mould legs like and fix them to the motors.spider cons4

Yes It may not look good.  Soon the spider hits the floor and the spider is still in progress.

  1. power Source: 3.7V,2600mAh
  2. CPU: ATmega48 clocked 1.536MHz
  3. Actuators/servos: HS311
  4. Sensors: yet to be added
  5. Programming: AVR C
  6. Environments: indoor

and many thanks to the Sir protowrxs.

Little update: 17th january of 2018

Modifed the legs style looks perfect and walking is also good.

I will add sensors to it and will update as soon as possible. Thank you all.

Robot project

master-slave robot arm  or teleoperator, this is one of my oldest project which I was built in 2012, For this simple application I did used NE556 IC to control Servo motors,  It is a dual timer chip and yep brother of very famous chip called NE555,  NE556 dual timer chip, one timer  configured in astable mode and output of it is connected to another timer which is configured in monostable and the pulse width is controlled by simple potentiometer or variable resistor which is connected in monostable circuit(RC network), Monostable output is a control signal further conneted to control terminal of analogue servo motor.
