RM-NCH4  - Nano Chassis 4

The chassis is  currently being vigorously tested by teams of college and university students. 

The construction concept is based on flexible modules that are assembled together as required. The main component  is the motor -chassis  that houses the two Nano- motors and wheels.  Additional metal plates can be added to construct a robot into many shapes and sizes. These additional plates could be replaced with plastic sheets or even  PCB's with embedded electronic controllers and sensors. 

 

 

 
This kit is precision CNC machined chassis made from one sheet of aluminium. The sheet is easy to bend into the required shape as the following pictures depict. The design has been keep as simple as possible to easy and low-cost  robot swarms the construction. 

 The CNC program can be easily adjusted to create various custom designs for different project. 

 Using just flat-nosed pliers, the first step is to bend up the sides and wheel mounts. The bending position is marked as notches on the plate.

 

Place a 6,5mm drill bit, metal rod  or even a pencil into the chassis to form the round motor straps. 

 

 Insert the Nano-class motors into place and tighten and lock the straps into place. 

The wheels then need to be assembled. The parts included are:

Motor, 3mm  shoulder screw, precision machined aluminium wheel, miniature ball bearing race and a rubber drive belt.. 

 The ball bearing race is placed inside the wheel housing;  as a "press-fit". The shoulder screw is placed inside the assembly ready for fixing to the motor block housing.  

 

 
Attach wheel assembly to the chassis and fix the drive belt. Repeat on  the other side.  That was simple!  The motor chassis is now complete. 

There is sufficient space between the two motors to fit batteries or even a motor controller PCB./ . The motor chassis is just 24mm-25mm square and only 14-15mm high 

 
Add 4x  plastic PCB stand-off's and any other front / back fixing  plates  to complete the basic construction. As you see there  is adequate room for additional PCB's and sensors.

The above picture depicts the completed nano-sized robot with a Megabitty controller PCB place on top. There is plenty of room underneath for line sensors or underneath  the  Megabitty board to attach additional sensors boards (such as the IRCF-Junior) or additional batteries.
