Marvin is built to destroy other robots in a compition.
Sorry I haven't posted lately, I've been overwhelmed with (home)school stuff, but I now have time to build! STAND3R is more of and experimental project. STAND3R is built to stand up from a belly-on-the-ground position. STAND3R has a gyro, a IR, and a colour sensor, along with 4 motors, 2 large and 2 medium. STAND3R would be able to walk, but he doesn't have the capability. If you added 2 more motors and added 2 legs, STAND3R would become WALK3R, but I don't have the money (yet) to get 2 more motors and another EV3 brick (one EV3 brick can power 4 motors, 3 at a time.) . Click additional info for more!!
This was a fun bot to build. I wanted to squeeze as many sensors and motors as I could into a good exploratory bot. It has 4 large motors powering the tracks and turns are controlled by a gyro sensor. It has two Ultrasonic sensors on each side to avoid obstacles. On the arm, it has one medium motor to control the claw with an IR sensor attached to enable it to home in on a beacon. The arm is controlled by one large and one medium motor. There is also a touch sensor that lets you start the program. The program and video are forthcoming.
Built for "Year of the Maker Building Challenge"
This could be a simple robot, but as a six year old, this is the best one I built and I feel proud to build something which can help blind people.
This I built for another local robotic competition, but they denied it because of my age. Hope here everybody will accept my idea. My father told me that some of these ideas could be already there as products, but all these are my thoughts came to my mind.
[Comment from Sarang’s father: I gave him the idea to build something to help blind people. I covered his eyes and made him walk, and after that each ideas he only found out in a long thought process. I merely helped him to understand the new concepts like code words from remote etc. ]
This is only a model which include the below feature.
1 Infrared sensor which senses the distance to other objects and produces a warning message “Stop”, with which blind people can stop and get a new direction
2 Same Infrared sensors which can find the remote control and identify the beacon switch setting and announce “one”, “two” etc. My real plan is to send some code word from remote control with which we can identify different places in a public building. Example when a blind person enters a bank building he can point the walking stick to different direction and hear voice like “Manager”,”Cash”, “Reception”, “Toilet” etc, and thus can move in that direction. The remote controls will be placed on top of all such doors
3 Switch placed near the handle which when pressed will make a “horn” sound, with which others can be alerted about a blind persons presence and can make space
4 Brick will flash LED lights, which in the night will help to identify the blind person. In this model it is pointed to back side, that need to be corrected in final version
5 Ultra sound sensor placed at the end of the stick, which can sense large stones, staircase, steps etc. In the software (EV3 home edition) I could not find the control for ultra sound
Issues with the model
1 The body is not very strong
2 When one infrared sensor is used for sensing distance and remote it is slow. Tried to change the program based on advice from father, but no improvement. Please help me. Removing the big loop from the program will speed increase
3 Ultra sound sensor is not programmed as my software does not have control. Could you please help me
This robot has two modes:remote and deliver!In remote mode,you can command it with the remote beacon,but in the deliver mode,you can let it follow black lines and deliver for you!When the deliver is complete,it will get back by it self!
I want to share a Robot I've created
