What does it do?

Modified RC obstacle avoidance Car

Very new to this site. Been playing with this project on and off for 6 months. Completed once then went back to and it wasn't working. Tried to troubleshoot and burnt out the chip. Pulled out the whole circuit board. Then rewired the battery pack. At that point it is just the frame DC motors on front and back(front geared to turn right and left, back left as dc motor for fowards and back) . I pulled an H bridge chip from a motor drive expansion board and breadboarded it .

Doodle Bot - beginners platform

The Doodle Bot is a very simple robotic platform for beginners, students and hobbyist.

The Chassis is a simple laser cut panel with two ball raced geared motors and a servo for raising and lowering a white board marker, jumbo chalk or crayon. Each wheel is fitted with an 8-pole magnet that is monitored by hall effect sensors to form two simple wheel encoders.

What does it do?

Draws nonsensical pictures

Having one of those days where your too lazy to do anything? Have a robot doodle for you while you sit back in your favorite chair. This is a very simple drawing robot that was actually started by one of our student engineers. I just made the base plate bigger so I could add a third servo to raise and lower the pen.

My base plate is laser cut acrylic but it could easily have been a small food container, CD or a piece of wood. Just use some double sided tape or hotglue to hold it all together.
