SLAM possibilities,where does it end ?
Hello,
the goal : something that looks like a droid, able to do SLAM without falling down the stairs
the problem : the more I dig, the less I think it's feasible, even by spending money and hours around ROS configs/packages and hardware
- at first I wanted to use sonars,then distance sensors on a servo, then RPLIDAR
then I realize they have limitations (I don't want a rotating widget on the top of my robot that only detect obstacles on a plane of sight at a couple of feets above the ground)
- so I thought, doing slam based on opencv-stereo-cameras-features like approach would be better; I found SLAM articles/videos about using Intel D435 cameras; then even more limitations (needed better odometry/IMU/off load SLAM...)
then there is the D435i camera; then I found the Intel t265 camera; optimized for slam with integrated IMU and stuffs(yet, grayscale fisheye, no depth available...map memory size ?)
now I am really lost and confused...
- I really don't wanna spend a lot of money on devices that won't work or don't do what I need, or worst, will end up not supported anymore, beeing super complicated to interface/tune within ROS
- then finding out a new/better device is now out there (a couple of days after receiving what I ordered)
- SLAM is one problem among many, I want to focus on other parts of the robot (TTS, voice recognition, actuators...)
any idea/opinion on this ?
am I going the right way ?
is slam possible for a hobbyist or is it only possible inside money loaded universities ?
thanks
