QR code integration
 | 
Submitted | 
The critter needs to be able to read QR codes and compartmentalize that information on the site in a useful way.  The code for reading the QR codes is already available and it has already been tested on the critter cam.

Bump sensors
 | 
Submitted | 
Physical bump sensors need to be designed, configured, and activated on each of the 4 sides of the critter to detect bumps and force the critter to immediately stop and prevent future movement in that direction.

IR proximity trigger sensors
 | 
Submitted | 
In addition to the bump sensors, install several IR proximity sensors that will not measure distance but trigger if the critter is too close to a surface to prevent movement in that direction.  The rangefinder will then no longer be used for collision detection and just mapping

Bridged access point

Set up a bridged access point in or near the kitchen to give coverage of that part of the house where signal loss is common.  Ensure that the critter can maintain a network connection while switching between access points as needed.

Gradual Acceleration
 | 
Approved | 
When starting to move and stopping, make the accel/decel more
 
gradual rather than the abrupt start/stop that occur now.
