Published on Dec 5, 2015

This is the 1st remote control (RC) project in my channel. I did not make the RC circuit, rather took the transmitter and receiver circuit from an old RC toy car. The RC circuit is based on IC TX-2B and Rx-2B. The robot which was controlled is from my previous post (climbing robot). If the motor rotates clockwise/forward the robot climbs up. If it rotate an-clockwise then the robot climbs down. Following links will help you to get more info about the RC circuit.

How to make a toy Woodpecker

Published on Jun 4, 2016

I saw this toy in few youtube channels. I dont have those exact materials but I was very much tempted to make it. So decided to make my own way. I suggest kids/students to make their own toy too. Until you make your own toy you will not achieve the skill.Even the idea is not yours, still try to make with the material available around you. More hands-on will help you to achieve better skill.

Lets modify The Runner and The Mover to do some fun experiences.

We added a tail and removed the front load. It started running like a lizard. Then we modified the Mover. The front motor was disconnect form power. The rear motor was given power external supply. We found the C wheel helping the robot to jump and cross the gap. We tried with different voltage and different initial leg position.

how to make a solar powered six legged robot - DIY Robot

Published on Sep 30, 2016

I took the robot Hexa, a six legged robot, which i made in my previous video. It was powered by a Li-Po battery. In this project we replaced the battery with a 5V, 160mA solar cell. This battery less robot was able to walk outdoor under sunlight. For further development, some can make it hybrid, by connecting both the solar cell and the battery. Solar power can be used during day time to charge the battery.
