1 ### Phase 2: Build TableTop Challenge Phase 1
5 * Cut out two pieces of Peg Board
6 * Drill mounting holes for sonar module
7 * Crimp connectors to cable
8 * Mount Sonar modules to Robot base
9 * Plug Sonar modules into breadboard + Arduino
10 * Develop table top challenge code
14 * 1 ?in x ?in peg board sonar holders
15 * 2 Sonar sensors (EBay: HC-SR04 ~$4/2)
16 * 4 2x8 .1in Female IDC connectors
17 * 2 12in 8 conductor ribbon cable
18 * 2 1x4 .1in Male-to-Male Headers
19 * 4 #4-40 Phillips Pan Head Screws
22 * 4 #4 internal tooth lock washers
23 * 2 #6-32 Phillips Pan Head Screws
26 * 2 #6 internal tool lock washers
27 * 1 18" of twine (for a Wyland leash)
29 Additional Required Tools:
33 That provides the basic configuration.
35 ## Rechargable Battery Upgrade
37 This gets rid of the hassle of buying and throwing
42 * 2 7.2V 1300mAh LiPo Battery Packs (Trossen: BAT-7V1300M: $26/2)
43 * 1 LiPo Battery Charger (Trossen: KIT-CHG-LIPO: ($16+$11)/1)
44 * 2 Female Deans Connector (TBD)
45 * 1 DPDT Power Switch (TBD)
47 ## Raspberry Pi Upgrade
49 The DC-DC convert is rated for 1.5A and can be
50 plugged into the breadboard. The ribbon cable
51 can be assembled with just a vise. The RasPi
52 allows 5V to be injected over the cable. Obviously
53 the RasPi allows people to start trying out ROS.
57 * 1 Raspberry Pi Model B 512MB (Newark: $35)
58 * 1 OKI-78SR-5/1.5-W36: 5V@1.5A DC/DC Switcher (Digikey: $4.30)
59 * 1 2x13 Female Ribbon Cable Header
60 * 1 16-conductor chunk of ribbon cable
61 * 1 2x8 Female Ribbon Cable Header
62 * 1 1x8 Male to Male pins header pins
66 This upgrade requires some work.
72 * 2 Appropriate magnet ($2/2)
73 * 2 GM3 to magnet shaft adaptor
75 An adaptor from the GM3 to Magnet is needed;
76 this would be custom made out of some plastic.
77 In addition a custom PCB is needed to hold
78 the AS5055 which is a surface mount chip.
82 Something like the GMYLE using the RTL8191SU should
83 do the trick. With this it is possible to network
84 into your robot. There it may be necessary to have
85 separate power injection for the Wi-Fi.
89 * 1 USB WiFi Dongle with decent antenna (Amazon: ~9)
93 This RasPi camera has not shipped yet, but it seems
94 to be nearing the end of prototyping. A USB camera
95 is another alternative.
99 * 1 RasPi Camera (~$25)
104 * 4 Hobby servos (base twist, shoulder, elbow, gripper)
105 * 1 Gripper (Jameco 358811: $20)
108 This is a low payload arm that can lift 10-20 oz max.
