1. Safety Sensors (IR and ultrasonic compression)

2. Concerns about sensors  Price  Range  Coverage  time  Temperature sensitivity

3. Design Vs. Buy OTS  Design our own Advantage low cost Design to spec Disadvantage -Time -Not appealing  Buy OTS sensors Advantages less time Easy to manufacture appealing Disadvantages costly

4. Additional Accessories -addition to safety -addition to wow factor

5. Status lights + Auto lighting  Status lights  Auto lighting

6. Status lights  Individual color LEDs indicate the operational status of the robot  Example of an LED driver (analog.com)

7. Auto-Lighting  By using ambient light transducers, or photoresistor, lighting around the robot can be turned on/off autonomously Picture of a photo-resistor and circuit Light detector with built-in signal processing circuit for light modulation system Ambient light detector (microsemi.com)
