Completed Robotics++ V2 Robot. More views of completed robot can be found at the end of this instructions manual The fun starts now! 2
Parts included in the V2 Kit 3
Step 1: Assembling the Motors Parts: (2) Servo Motors (12) ½ inch screws (12) 4-40 lock nuts screwdriver (4) plastic servo holder brackets (2) servo holders Note: You may also refer to the pictorial parts list to learn more about each component 4
Insert the servo motors into the servo holders and secure them with the screws and nuts as shown on the right photo. Please Note: - how the motors are inserted into the servo holders - how the screws face in on the servo holders - how the shaft of the motor is on the front on both left and right sides. - bottom holes on the servo holders must stay on the bottom to mount the plastic servo brackets Hole for shaft servo bracket 5
Notice how the position of the shaft on each sensor holder is on opposite ends 6
Step 2: Assembling the plastic servo holder brackets Parts: (2) 4-40 nuts (2) ½ screws (2)plastic brackets 7
Paying attention to the direction that the screw goes, assemble the plastic brackets as shown below on both servo holders 8
Step 3: Assembling the Line Following Sensor Parts: - lower chassis - line following sensor - (2)4-40 locking nuts and ½ screws - screwdriver Insert line following sensor as shown below. Note: pay attention that the chassis is facing up and you can read Robotic++ FRONT 9
We will install the front plastic acorn nut first Using the ½ inch flat head screw and 4-40 lock nut proceed to install as shown below. Note: - Try to tighten the acorn nut as much as possible Parts: - ½ 4-40 flat head screw - 4-40 lock nut - plastic acorn nut 10
Step 4: Assembling the Feelers (switch) Sensor The feeler sensor are metal piece that is assembled so that when it touches the metal screws completes the circuit and can trigger a response. These are secondary sensors in case our other sensors do not work. Parts: - (2) ¾ inch flat head screws - (2) Dupont M/F wires - (2) jumper wires - (2) ½ screws - (6) lock nuts - (2) metal feelers - Screwdriver - Lower chassis 11
Insert screws as shown. Note: - two larger screws (3/4) flat heads go in the center and the other two ½ screws go on the sides - Two larger Dupont M/Fwires go in the center and the two smaller jumpers go on the side held by the lock nuts 12
A Closer view of mounting of metal feelers, screws, nuts and wires. Metal feelers should not be touching the screws as shown. You might need to borrow some pliers from uncle Bob to tighten these nuts Make sure they feelers are not touching screw 13
Another view of the metal feelers installation 14
Step 5: Assembling the servo motors on lower chassis Parts: - the two servo assemblies - lower chassis - (4) metal spacers - (16) ½ inch screws 15
Install servo assemblies as shown on the top side of the lower chassis using the metal spacers and the ½ inch screws. Note: don t make it too tight yet as you need to put the upper chassis and might require some adjustments Also, make sure servo shaft points to the front of chassis Servo shaft points to the front of the chassis 16
Step 6: Assembling the battery holder and back acorn nut balancer Parts: - Battery holder - ¾ inch flat head screw - Plastic acorn nut - Lower chassis - 4-40 lock nut - screwdriver ¾ inch flat head screw 17
Complete battery holder and plastic acorn 18
Step 7: Assembling the lower chassis and Arduino board Parts: - upper chassis - (3) plastic spacers - (10) ¼ inch screws - Arduino board - screwdriver Use the 3 plastic spacers and three ¼ inch screws and install the spacers on the Arduino board as shown below Install 3 plastic spacers 19
Completed assembly of Arduino board on top of upper chassis Note: - Arduino board can only go in one direction. The holes on the upper chassis match the direction that the Arduino board should go 20
Mount the upper chassis to the four metal spacers as show below using the ¼ inch screws. Also install the Arduino Sensor Shield as seen below. Note:- Pull the servo wires thru the holes as shown below for each side Install power switch as show here-> ¼ inch screws Arduino Sensor Shield v5.0 21
Step 8: Assembling the wheels Parts: - (2) wheels - (2) screws from servo motors parts bag to mount wheels - screwdriver Insert wheel carefully, but with force to the shaft of the servo motor. Use only the screws that come in the bag of servo horns. These will make sure to hold the wheels. Wheel screws comes in the servo bags of spare horns 22
completed chassis and wheels assembly 23
Step 9: Installing the Breadboards Peel off back from the double sided tape on the breadboards and install them as seen below Parts: - (4) breadboards 24
That s it! Now we can start the experiments to learn how to program the robot with creative algorithms, motor control, basic electronics and sensor interfacing. Please visit http://www.roboticscity.com/ to download these exciting projects. Have FUN! 25
