RTK-000-003 Robot Assembly Guide

What's included with the kit:

  • 1 - Robot Chassis
  • 1 - 4 AA Battery Box
  • 2 - DC Motors & 4 Wires
  • 2 - Wheels
  • 1 Medium Sized Screwdriver (Normally Included)
  • Screws, nuts and bolts
  • Caster Wheel
  • Motor Controller
  • Wi-Fi Adapter (If Ordered)
  • 2 Plastic Encoder Wheels - Keep these in a safe place for future upgrades!

What you require extra:

  • 1 - Raspberry Pi (Any model will work, we find that A+s go the best on robots).
  • 1 - Power method for the Raspberry Pi (A USB Battery bank is usually the best)
  • The Motor Controller Board Soldered Up (View the guide here or pre-soldered when purchased with the pre-soldered kit).
  • The 2 DC Motors soldered to the 4 wires (Pre-soldered when purchased with the pre-soldered kit).

Step 1 - Attach the brackets to the motors

Start by getting your two motors, the 4 long screws, 4 Nuts & the Metal Bracket Blocks. 
Screw the bracket on the side with the wire in, you will need to make sure its on both sides for each motor. Here's how ours looked after. 

Step 2 - Attach the motors to the chassis

Next get 4 medium sized screws and attach the motors to the chassis with the wires in the middle. 

Step 3 - Attach the caster wheel

Next get 4 nuts & the 4 stand offs, (We attached these in the picture above at the top) using the nuts on the top and the screws on the stands into the nuts.

Then place the caster wheel on top and use 4 screws to screw the wheel into the stands. It should then look like this 

Step 4 - Battery Pack Mounting

We found a neat little way to be able to create a holder for the battery pack. The way we do it also means the battery pack can be removed when you want to change the batteries.

Start by getting 2 screws & 4 nuts. In the second row of spacees from the caster wheel. 
Screw the screw in from the bottom and use a nut to hold it loosely in place. I then placed another nut ontop to make a spacer as you can see below. 

Then use the battery pack and move the screws to align and fit in the two holes on the pack. Once you can push the battery pack on it should sit tight without needing to be bolted down. 

It should then fit nicely on. Here's a preview from the top:

Step 5 - Motor Wires & connecting up

Next push the wires for the motors carefully through the hole directly above them.

Now connect each motor to one of the motor terminals on the Motor Controller board and the 4 AA battery pack to the VCC2 Input on the controller board.

Finally you can now place the rest of the components in a layout of your choice. Here's how our robot looked with an A+
