Trinity chassis update!!!

Dear: CKR

Just letting you know I have been having problems with lack of space, sensors, motors, and more with my trinity robot. My last robot for the trinity challenge I didn't like the sensors because they didn't use machine vision. So in other words it could mistaken a teddy bear for a obstacle in the challenge unfortunately because there have been instances of that in the trinity challenge. This robot's sensors I gained inspiration for submersable robot cameras that use two different colored lasers that are parallel with each other and perpendicular with the camera. The camera is a pixy CMU by the way.

Then I have two stepper motors for moving the robot. Luckily because of my 3d printer build I have a ton of spare motor drivers for stepping. Never thought I would use them though. The stepper motors I am using are really high quality Nema 14 steppers. They should do the trick.

I am going to use these to mount it to the chassis.

I am also going to use a cpu cooling fan to put out the flames. Below is the mount for the cpu cooling fan.

Here will be the assembly.

Wish me good luck!!! Thanks!!!

What are you planning on using for distance sensors?

I am using laser to see distance with machine vision. The two lasers are perpendicular to the camera and are paralell to each other. There is an algorithm for doing this with machine vision. Thanks!!!

To be competive at Trinity you will want to be moving at least 40cm/sec. I suspect you will need distance updates at least 10 times per second to avoid crashing into walls in front. What about staying off the side walls? .

You should know this robot is very small. It doesn't need to have a seperate sensor for seeing it's side because if it moves in zigzags it can identify it's sides pretty easily. That can be achieved because the robot is smaller than 14cm. Thanks!!!
