How to operate Robot Arm Kit?

wired-control-robot-arm-kit-robotic-arm-and-gripper-rm0770-by-robomart-840-500x500ROBOMART  has a robotic arms kit which is fun and has the practical aspects of leaning which includes basic robotic controls that are used in various mechanized firms. We are going through it’s  features and usefulness.

The first thing which we look into is to assemble the ROBOMART ARM KIT.There are certain items which we need to have or we need to acquire them before we assemble them.

The tools needed  are as under:

  • Diagonal cutters.
  • Needle nose pliers or long nosed pliers.
  • Glue stick (not liquid glue)
  • 4 “D” batteries.
  • Philips screw drivers.

Once you acquire all these items you have to open the ROBOMART ROBOT ARM KIT edge box and then remove the assembly and instruction manual.Then you have to review the manual to get familiar with the procedures required to assemble. You can also refer to the Mechanical Parts List given with the kit and plastic parts list given in the Kit way to a so that you will come to know the way to assemble  the robotics arms .

The Assembly begins on page 5 given in the manual and the instructions provided help to locate spine A and helps to remove part A2. There are two of the A2’s so detach one of them and then use the file to file  the burrs. Then you have to get four (4) hex nuts named  as part P18.P18 * 4 means that there is part number 18 and is four (4) in quantity.

The picture box indicates  the correct way of how to insert the nuts by top box with shows large O and lower one with large X indicates the incorrect way of inserting the nuts.This type of notifications will be shown in the manual. At this stage of the assembly the nuts did not necessarily stay in position as the gears and motors are inserted in it.The magnetic pull of  internal winding cause the motor nut closest to it become attracted to the motor housing.

One of the prominent solution was to use a glue stick and put the nuts into glue before inserting them so that they should firmly hold each other. If one puts some glue into the hole of nuts and then place the cover which is A1 over the gears and the motor in the  step 4, page 6 then we should  use a small wire which cleans the excess glue.

We  have  to continue with the steps outlined and make  sure that the correct motor is placed in gearbox based on the wire colors attached to motors. The motors are not numbered or labelled but are assembled in an order based on the wire of the colors. Also, when you insert the motors make it sure that the capacitor has been pre soldered and not visible but rather placed down as pictured in step 3 on page 6.

The assembly of each gearbox continues the same until page 9 when a white output gear (P8) is inserted into the gear assembly for the motor number  2. Obviously The reminder is provided  in step 13  when each motor assembly is pictured showing there designation (M-2,3,4 AND 5).

Next the motor 5 is shown starting with step number 14. In 17 number step, notice that the  harness with the molded wire will be running along the battery compartment which is used to hold the ground wire which is orange.  As you place the wire in harness, make sure the  wire which is orange in colour  is put in such a way so that batteries do not damage the wire.

pic9                   As with the assembling of the parts make sure that you know the direction and placement of specific parts.In step 24 make sure that you notice the direction and placement of specific parts.In step 24 make sure the assembling of parts F2 and F3 have the knob to right of M2 Gearbox assembly which is shown in the picture.

In step 25 in the drawings it shows part E2 with a bracket on the right side.On both E2 pieces the bracket pieces  are kept  for the purpose of holding the wires in place. Their placement is like wire ties kept in reference for their placement, now you can look  ahead on page 25 which shows step 45. There is placement of the parts with step 30 and 31.You also have to follow the steps of sequencing on page 19 with care.

You also have to complete all of the steps in assembling of the robotics arm, which continues with assembling of the wired control box from page 27 to page 30.The USB interface kit which is included in the kit will be installed afterwards.

Once you get the robotic arms and control box assembled, then test the arms operation with the maneuvering of outlines on page 31 to 32.AS you testy the movements and operations of arm, you will hear a clicking sound. Sound will resemble as if  plastic gears are breaking or it is working to protect gearbox.


The first step is to locate the USB interface kits for robotics arm edge box number (535-USB) that was in kit.The USB interface kits contains the necessary items which allow for connection of robotic arm edge to a usb port.The kit is suitable for the OS operating system listed on the box.if the OS  is not  windows then you may need to contact Robomart and information is listed on bottom of the box.

The particular kit used in preparing this study guide was compatible for windows based vista, xp and 7 which works on 32 bit and 64 bit version.Once you have located the box remove the assembly and instruction manual and review steps to  swap out the wired controller with the USB interface.You will need a screwdriver and it is best to inventory the contents of the box which makes sure you have the USB cable, PCB cover yellow) USB PCB assembly and cover.

Once you have secured the cover and reinserted the motor wires, insert the CD into the computers CD drive and select either the 32-bit or 64-bit folder depending on your computer or laptop. Click on the pdf manual to follow the instructions on loading the CD onto the hard drive.


It may be good if you print out the copy of the USB PC interface user’s manual to check off the steps as they are completed but it’s not a requirement.Then you have to select the OS which is compatible to computer or laptop the software is being installed on and follow each step until the screen shows installation.Once you install it you have to make sure that the switch is on at the start of the installation process.

When the installation has been successfully completed, review section 4 of the manual. Section 4 is on “How to Play” and illustrates how the BASIC mode and PROGRAM mode functions. It is a good idea to gain some familiarization with the modes before getting into more complex programming.


One can work with the robotic arm by moving objects around the home. One should remember that objects weight should be less than 100 grams.

For Example: You can pick up the glue stick or a tennis ball, pens, pencils, you can say that any small weight objects will work for you to pick from robotic arm. The control mode can be selected for mouse control or keyboard control.

The basic mode is same just like wired control box. When one uses the keyboard control or mouse control the cursor over the letter/symbol and the motor type will light up on robotic arm on computer screen. The letter W and S apply to gripper (M1) letters E and D apply to wrist (M2), letters I nad K apply to base (M5) Letter L is for light.


If it has not been done before,  then you have to print the interface user’s manual from the software CD.  We are interested in section 4 “How to play”. The section 4-5 program mode is part of manual which describes display areas and we have also included screen shot below for your reference. One should get familiar with the controls and displays.


First area to be discussed is the Write data area which allows us to enter operation time, in seconds for different operations control. Also the display area indicates the same. The write data area allows for adding controls to program list, insert a movement before data in data box and overwrite data in data box.


The next area is file area which is used to create file, open saved file, save program and return to the menu by selecting close.


The program tools area allows program to run when start button is clicked. If program is repeating or it is a long running program, stop button will stop execution of program. Rewind will reverse robotic arm for duration specified or lets say it runs runs program in reverse order. Delete allows for the removal of command when selected.


In section 4-6 there are altogether 14 steps which discuss and show some of the programming features and commands. You have to complete each step as part of experiment to become familiar of program mode’s functionality.One note to make is that if you leave robotics arm switch to off and enter a few quick commands before testing operation.

You are now ready to develop your own programs and learn how to manipulate objects using robotic arm that is controlled by your computer or laptop.
