hi, i am building a rover robot. i want it to do some object avoidance ( obviously ) and maybe in the futere some mapping and path finding.
i don't want it to hit something an than say, "hey here is an object". i want contactles detection but here comes the catch. the robot is 50cm x 50cm and will be use in- en outdoors.
one sonar is not enough to detect all angles an scanning is way to slow for indoor or maybi that's my programing
. using more sonars (>10) will quikly become verry expensive.
the sharp range IR sensors are not relyible outdoor but are cheaper and can be used by the dozen.
can someone give me some advice or mabe a third option?
ps: lidar is no option unless there is a cheap model that actually is for sale
