1. IMDL Robot Presentation EEL5666 Robert Hartwell 31 Jan 2012

2. Summary 1: Scope – Take a wireless drink order, navigate to drink station and correctly mix the drink 2: Gain from the solution to the problem – Mixed drinks and inebriation 3: Approach to the problem – 4 wheeled mobile platform with servo actuation, drink mixing station 4: What has been done – Design of the mobile platform. Design of drink station. Ordering of sensors, chassis, servos, motors, materials for “arena”, materials for drink station, misc building supplies (wood, hinges, wiring, break out boards, etc). 5: Results to date – Uploaded and executed blinking LED code to microcontroller, most planning completed 6: Future plans – After BoA sends me a new debit card (because some Eurotrash stole my number and bought a lot of clothes in Italy and France), order the Xbee modules. Construction, sensor testing, coding.

3. Introduction Completed work – Chassis design – Mixing station design and dispensing method design – Actuation of individual containers design – Sensor and servo placement on chassis design Scope of sensor and movement control – Wireless communications – Color Detection – Bump Sensors – IR Detection – Motors and Servos
