BinaryBots Totem Crab

BinaryBots Totem Crab

                Today we will look into one of the robots which are called the "Binary Bots Totem Crab". This robot is one of the product under Binary Bots. As the name goes, this robot has a similar look to the crab. This robot uses the micro::bit as it controller. The board does not come together with the robot, you need to purchase it separately. This robot is suitable for kids 11 years old and above. Once we have all in place (as per image below), we can start to assemble the robot.

                    One good thing about this robot is that the items or the components are packaged individually according to the steps outlined. The image below shows the components inside the box.

              The building of this robot is pretty simple since the guide provided are very detailed and easy to follow. The building of the robot steps is shown as per the guide provided.

STEP 1 - ASSEMBLE THE BODY - 
BAG 1

For Step 1 we use the item from Bag 1.

The first step of building the robot is to prepare the beam.

The next step is to attach the beam to the base of the robot together with

the L shaped bracket.

STEP 2 - ASSEMBLE THE LEGS - 

BAG 2

For Step 2 we use the item from Bag 2.

Next, we, prepare another set of beams.

Installing the bracket to the beam

For the image below, the actual item provided was not the same. In the manual,

it is said that the "L" shape should be pointing toward the other side, but

the actual item which was provided is pointing toward a different direction.

Not sure which is right. But it is still possible to fix it to the beam.

This is the complete beam for installing the leg.

The image below shows the six legs we prepared.

The legs are attached to the beam.

STEP 3 - ASSEMBLE THE SHELF - BAG 3

For Step 3 we use the item from Bag 3.

Next, we prepare the body or cover of the robot.

This the complete body that we have finished.

STEP 3 - ASSEMBLE THE SENSOR
BOARDS - BAG 3

This the BinaryBots Power Board

This is the BinaryBots Sensor Board

Attaching the BinaryBots Power Board to the body of the robot.

STEP 4 - ASSEMBLE THE CLAW - BAG 4

For Step 4 we use the item from Bag 4.

Preparing the claw of the robot.

The complete set of the of the robot with the claw being attached.

Next is to prepare another set of the claw using two pieces of a triangle.

For this part, one of the nuts was missing. hence I need to look some other part which suits.

Luckily I found one in my inventory

Below is the completed TotemCrab robot.

Once all the parts are fixed, the last thing to do is to put the micro:bit into the BinaryBots Power Board provided slot.

 Coding The TotemCrab

The first for the coding is to connect the board to the PC and get the driver updated. Once it is done, go to https://microbit.org. And start to code as per the manual.

There are 2 different methods to write a program for the TotemCrab.

• the first is by using the block
• and the second is by using python

Below is the video of how we can use the micro:bit online tool to write a program using block

And this is screenshot of the block coding

The image above is a simple program to run on the BBC micro:bit.

Below is the demonstration video of the BinaryBot Sensor Board. 

And below is the video demonstration of the fully working Totem Crab.

For the above demonstration, we use the Python language to make our program.

Below is the screenshot of the code.

Thank you.
