Project Plan | Badger Tunnel Ranger

2. Introduction - Motivation
YLE wants to make a nature document about badgers
Ulos luontoon -series
Around viewers
Robot for filming badgers’ nest and tunnels
Mechatronics team: mechanical and electronical design
Automation team: software design
Video material has scientific value
No video material before from inside nest
Badgers
->outside the den have already been filmed
-> are mainly unexplored
Nobody knows the real size of the den
Trying to keep the disturbance for the badger very low
expose badger -> create awareness of these animals in publis
Project Plan | Badger Tunnel Ranger

3. Introduction - Requirements
Badger tunnels
Narrow (around 30x30cm)
Can be 6 meters deep
Have many floors
Steep slopes
Rough terrain (roots, wet dirt)
Recorded and live view outputs
HD TV quality
Mapping system
Robust
Retrievable
Cannot damage badger tunnel
Robust to withstand environment and attacks from the badgers
Project Plan | Badger Tunnel Ranger

4. Project goals Remote controlled robot
Able to navigate and document badger tunnels
Design system to control navigation and filming of the tunnels
Keep the device small enough to navigate the tightest tunnels
Utilize a cable to tether, power, and recover the robot
Design extensible robot platform for multipurpose use
3D modelling of the badger tunnel

6. What kind of problems might occure?
Robot or cable can get stuck
We don’t know what there is inside the tunnels
How to get it back without damaging tunnels?
We might disturb a badger
It can attack and break the robot
Field testing might be difficult
Badgers sleep in their tunnels during winter
Lighting for good quality filming
Reducing the size
Cable:
friction of the cable increases
robot should be powerful enough to pull the cable
recovering the robot might damage the den
just say: What problems have we encountered yet?
-> different deadlines of the project
-> define the responsibilities
-> structuring the teamwork
