1. Assemble the Hack-E-Bot


First you will want to verify that you have all of the parts you need for making your Hack-E-Bot.

All parts needed to assemble the chassis.

  • 2 Zip-ties to secure the servos and 2 more for spares.
  • 2 Servo mounts.
  • 2 Wheels.
  • 2 small wheel screws.
  • 1 base disk.
  • 2 Small vertical spacers.
  • 1 Large vertical spacer.
  • 1 top disk.
  • One set of pre-wired FeeTech FS90R continuous rotation servos (Data Sheet).
  • Battery box with a power switch for 4 AA batteries.
  • One HC-SR04 Ultrasonic Sensor (Data Sheet).
  • The Adafruit Pro Trinket Arduino based micro controller.
  • Micro USB cable for programming.
  • Information on accessing the information website.

Install the Drive Servos

1
Flip the bottom disc over so that the ball wheel is facing down. Insert the smaller tab of the first Servo Mount through the small slot near edge of the bottom disc.
  • The flat side of this part should face the oval wheel slot.
2
Swing the Servo Mount down to fit the rounded tab into the longer slot in the base disk.
3
Slide the first servo into the rectangle cutout in the Servo Mount.
  • Be sure that the white servo shaft sticks out into the center of the oval wheel slot.
  • The servo should fit snugly to the back of the Servo Mount.
4
Using your thumb to gently press the servo against the bottom disc, flip the disk over so that the ball wheel is facing up. Feed one of the included zip-ties through one of the small square holes on either side of the servo. Note: Be sure to turn the Zip-tie so that the head will lay flat when tightened.
5
Flip the bottom disc back over and feed the zip-tie over the servo and under the overhanging servo mount tab. Continue to feed the zip-tie through the small square hole on the other side of the servo.
6
Flip the bottom disk back over, feed the zip-tie tail into the head and tighten it down as much as possible with your hands.
  • If you have a set of pliers, use them to tighten the zip-tie a little more.
7
  Install the other Servo Mount and Servo, just like in steps 1-3. Just like before, feed one of the included zip-ties through the small square hole on either side of the servo. Note: The smaller slot for the right side servo does open into the larger power switch square cutout. This will still function the same as the other side, though it may look a bit different.
8
Flip the bottom disc back over and feed the zip-tie over the servo and under the overhanging servo mount tab. Continue to feed the zip-tie through the small square hole on the other side of the servo. Flip the bottom disk back over, feed the zip-tie tail into the head and tighten it down as much as possible with your hands.
9
Use wire cutters, scissors, or fingernail clippers to cut the end of the Zip-ties off.

Install the Wheels

1
The wheels should fit onto the Servo shafts on ether side of the Hack-E-Bot.
2
Use the included screws to firmly attach each wheel.

Install the Power Supply

1
Take the wires from the Servos and move them so that they lay between the Servos and go to the front of the Bot.
2
Split the sets of wires so that the Red wire goes to the right side, the Brown wire goes to the Left, and each of the Orange wires go to the same side as its Servo is. Note: The front of the Hack-E-Bot has a large rectangle with two small holes on either side.
3
Check to see if the power switch is set to Off, then open the battery box and insert the 4 AA batteries. Place the battery box onto the Servo Mounts ensuring that the power switch is accessible from the large square cutout in the bottom disk.
4
Firmly press the battery box onto the Velcro pads to ensure that they stick. Note: The Velcro pads will securely hold the battery box onto the Hack-E-Bot while allowing easy access to change out the batteries.

Connect the Top Disk

1
Install the large Vertical Spacer into the front of the bottom disk.
  • Each of the Vertical Spacers has a flexible tab at the end. This allows these parts to be installed and removed easily.
  • With two fingers, gently squeeze the tabs together and snap the Spacer into it's corresponding slot.
Note: The Vertical Spacers may fit a little loosely, but that is okay.
2
Install the two smaller Vertical Spacers, into the back of the bottom disk, just like the large Vertical Spacer was installed.
3
Connect the top disk to the top of the large Vertical Spacer.
4
Connect the top disk to the top of the two smaller Vertical Spacers in the back.
5
Your Hack-E-Bot is now assembled and ready for action. The bot may move and flex a little, but you should be able to pick it up from the top without having any pieces fall off.
