A.Y.S. uses 2 VEX bricks with a slew of servos (continuous rotation and 210^) for the head, arm, and hand/ finger controls. Potential energies (gear boxes, rubber bands and springs) help with torque issues.
We were originally using PROPELLAR chips and circuits, but time contraints and audio issues made the team use an applet for the audio.
There are also a light and ultrasonic sensor that react and start the operations of the robot (when it detects you, it starts taking 'orders' / asking for tips and telling jokes). These are seen in the center with PWM wires and the ping sensor is under the front of the bar to detect movement.
This is bad pic of the inside of the robot (rat's nest!), but it has a Victor to control the wheels (window motor) the VEX bricks, and the batteries ( 2 VEX 7.2 volt and a 12 volt 1.3amp). Oh, and lots of wires, seen here in "being worked on" mode.
Thx to the seniors who worked on this project:
J Linc, Silvio, Tedesco, and the Tanap.
Big thanks to LINDAB engineering for the spiral round we used for the body here and on the R2D2 unit!
