Introduction: Building an Insectbot :D
Hey there! Welcome to this tutorial, in which I will show you a tutorial of the insectbot that I have put together, with a kit from DFRobot.
The kit includes:
- A Beetle (which is Arduino compatible)
- A Beetle Shield
- Two servo's (9 gr.)
- An infrared sensor
- A LiPo battery (3.7 Volts, 180mAh), and a charger included
- Two steel wires (200 mm by 1 mm) => these will serve as legs
- A 50mm by 50mm ABS sheet
- Double sided foam tape (30 mm wide, 40 mm long and 3 mm thick)
- Five cable ties (1,8 mm by 100 mm)
- A different cable tie (4 mm by 200 mm)
Step 1: Step 1: Soldering the Shield to the Circuit Board.
The first in making the insectbot, is to solder the Beetle Shield to the Beetle circuit board. Simply place the shield on top of the circuit board and solder them together. Be careful tough: make sure you line them up in the right way. The numbers should match, and so should the positive and negative poles.
If you have lined the two up correctly, solder the eight pins of the Beetle board to the shield.
Step 2: Next Up: Starting With the Body
The second step consists of connecting the two servo's to eachother. One of these servo's will make the front legs move, the other one will do the same for the legs on the back.
Place the servo's together in such a way, that one is facing upwards and the other is facing backwards. Also make sure that the wires of the servo's point upwards.
Once you have found the right position (see picture) to connect the two servo's, take the double sided foam tape and a pair of scissors. Then cut off just the right amount of tape to cover the sides where the two servo's meet completely. First remove a single side of the tape and make it stick to the first servo. Then take off the other side off the tape and connect the two servo's together.
To make sure the two servo's will stay in place, take the (only) big zip tie and apply it around the two servo's (see picture).
Step 3: Step 3: Making the Legs
Time for step number 3; making the legs. For this step, you will need the two steel wires and two plastic rotators that come with the servo's.
First, bend a steel wire exactly on the centerpoint (see second picture), this way you will creat two legs. Next, you will have to put the two steel legs through one of the rotators (see third picture), bend the top to the left and the legs to the right. This way the legs will be fixed it place and able to turn (see third and fourth picture).
Connect the plastic rotator to the servo with the included screw (see fourth picture).
Do the exact same thing for the second steel wire to create the legs on the back. If desireable, you can bend the legs itself as well, to improve to walking of the robot (fifth picture).
After completing this whole step, your robot will look something like the robot in the sixth picture.
Step 4: Step 4: Making the Head :D
To start making the robot's head and his eyes, you will need the infrared sensor, the ABS sheet, two short (red) zip ties and a screw.
First of all, you will need to cut out the form of a neck and head out of the ABS sheet (see picture two). Then you will need to make two tiny holes, so you can connect the infrared sensor to the ABS sheet. You can use either scissors or a small knife to do this (make sure you don't cut yourself!).
Once you have created the holes, you can start to connect the head to the neck (ABS sheet), see picture three. Zip it up, and you will end up with a robot head, which looks like the one in the fourth picture.
You can decide to cut off the rest of the zip ties, but I like the insect-look it gives to the robot.
Connect the neck to the robot, by connecting it to the front servo with a screw (sixth picture).
Step 5: Step Five: Putting Everything Together
One of the last steps already :)
In this step, we will simply connect the motherboard to the robot itself.
Cut out a piece of the double sided foam tape and stick it to the back of the robot (first picture). Then take your beetle, with the shield you soldered onto it, and stick it firmly to the other side so it will stay in its place.
Step 6: Step 6: Just the Wires..
Last step! :D
The only thing left to do, in a perspective of hardware, is to connect all the wires.
1) Connect the power supply. The wires of the battery will go on the top right of the motherboard. Make sure you connect the red wire to the '+' on the board and the black wire to the '-'.
2) Connect the infrared sensor (the eyes). The wires of this sensor belong on place 'A1' on the board. Make sure you connect the black wire to the '-', the red wire to the '+' and the orange wire to the 'S'.
3) Connect the two servos. The wires of the front servo belong to 'D9' and the wires of the back servo belong to 'D10' in the board.
Simply check if your wires are connected to the right place, by checking the picture :)
Step 7: Done!
Now you have a finished Insectbot! You can charge the battery with the included USB charger, and at the same time you will be able to program your robot :)
We have a be nice policy.
Please be positive and constructive.
