Leo's LiteCar

It's really not easy for me to start,but I am here!
I'm so happy to find this great place,with so many funny friend and robot!
This is my first project from last years which called “LiteCar” , I wish to program my LC running without Delay(); Feeling with a Light Sensor and Fighting with a "Laser Gun".

Project plan:
1,moving action(WASD) by Computer Operator
2,recording its absolute position
3,feedback and maybe some PID? or Balance Filter?
4,Automode:moving by some prepared positions
5,add some other sensor or what else...

Have the tools but need help with calcs

Hi guys.

 

I am heavily into automation in both my daytime job and my hobbies. I have always built gear I need. I have lathes, welders etc with access to milling machines etc, folding machines and other stuff.

 

I am building an autonomous hybrid farm utility. No issues with that.

 

I can do the the motor/gennorator etc, rams etc and all that. However, I need a push in the correct direction to calculate the drive train part. I know my required wheel size, weight etc so how do I work out size of the drive motors etc

Need consistent 90 degree turns. HMC5883L and Arduino Mega

I am currently working on a project for school. The idea was to create a robot that could perform pathfinding functions using A*. The path is found using a virtual grid of nodes programmed into the Arduino where "X"s are non-passable objects, "0" as the start, and "1" as the destination.

Not sure how to insert code on this forum. Someone could help me out with that as well...)

Example: 

Sits on the table, waiting for sunshine and once charged the cpas discharge and spin the motor for an annoying vibrating sound.
There is really not much to write about. I saw the nice freeform Annoy-o-tron 2000 and got infected. Grabbed one 555 timer as I saw a nice solar engine circuit … Read more
