i had search over google and found out more or less some sensor that i could use like sonar, gyroscope, accelerometer,magnetometer and gps and 2d lidar (which is less expensive, around $300) i have cost budget so i couldnt go for those expensive devices.
- works on outdoor. look at the image above with some description here: blue line is the border. red line is the path. black line is the building.
- when the robot at point A, and i input point B. the robot should be able to find a path from point A to B
- if point x is blocked, it should be able to find a way to point B via point Y
- ground is not flat. thus there might be need sense some higher ground level to avoid collision and recalculate the position of the robot
- works on day and night
therefore, my question is: what is the best device/sensor i should get to satisfy my features above. or probably any technique i could use? Please kindly share with me. maybe there is something i miss out on my research
Gps is good but the error is around 6m.. that is too large fusion of gyroscope, accelerometer, magnetometer to get a correct position and direction is kinda difficult(oblu maybe)
founding: i found 2 device that could help me with that
ZED stereo camera which works on 0.5m up to 20m.($499)
Intel RealSense 435i which works 0.1m up to 10m with IR.($200) both are not working so good in dark area even with IR. but i think a lighting could be installed to help with that
any other device recommendation ?
