How to Assemble R-Bot?

The R-Bot robotic chassis is a light weight, low cost, compact, medium capacity multipurpose robotic chassis which provides a great opportunity for rookies as well as pros to quench at least a bit of their limitless robotic passion carvings.
R-Bot is cut out of a 3mm acrylic sheet with 15 cm diameter which provides a strong and rigid platform to build a robotic chassis. Apart from bottom and top layer, an intermediate layer provides space for accessories like battery pack and more. Design is simple making it easy to assemble even for a school going kid and the circular design makes sure that the chassis doesn’t get stuck at corners.Two plastic geared DC motors with two premium quality rubber gripped plastic wheels powers the chassis along with a ball caster wheel for support. Top plate holds a micro servo motor with its pan head can hold proximity sensor like SHARP IR or RhydoLabz® ECHO Ultrasonic. The pan head can also be attached to the uppermost plate without using servo motor depending upon the application. An array holder is also provided with R-Bot capable of holding IR sensor arrays of various dimensions like Pololu QTR Reflectance sensor arrays.

Bottom and middle layer have just enough space to accommodate 2 4xAAA battery holders. But if the user wishes to add the top plate, there will be plenty of space to hold these battery holders. It simply means that the entire chassis is customizable as per the user’s choice; i.e. except the bottom layer, top and middle could be interchanged.

R-Bot always welcomes add-ons enhancing its features like providing multiple pan heads, array holds, and extra plate to increase payload capabilities and also an extra caster ball wheel can be provided to increase to stability of the chassis. Once fully assembled, it could be easily interfaced with a quick start board or an  Arduino™ development platform.

R-Bot Assembly Steps:- 

Step 1:Insert the motor holders in the slots as shown in the picture.

Step 2:Place both the DC motors in such a way that the motor shaft is at the middle of the  wheel slot.
Step 3: Screw each motor  using two M3 25mm screw & ensure that it fits wel.

Step 4: Attach Wheels to the motor as shown in the figure and use mushroom head 7mm  screw for fix wheel to motor shaft.

Step 5: Attach  caster ball wheel  as shown in the figure below, use M3 12mm screws.

Step 6: Attach middle chassis to bottom chassis using M3 25mm Female-Female stand-offs & fix M3 25mm  Male-Female standoffs on middle chassis to mount the top chassis.

Step 7: Attach micro servo & Toggle switch on to the top chassis as shown in the picture. Use two M2 12mm screws and M2 2mm nuts to fit micro servo.

Step 8: Attach top chassis to the M3 25mm Male-Female standoffs attached in step 6. Use M3 6mm screws to fit it.

Step 9 : Attach servo neck and pan head using M3 12mm screw & M3 2mm nut. Attach this to micro servo horn and then to servo motor using mushroom head 7mm  screw.

Now R-Bot  is ready to use.


Array Holder is also attached with R-Bot, as shown in the picture below
