T70098 Tamiya Universal Plate Set – ABS Construction Plate

The T70098 Tamiya Universal Plate Set is a versatile construction platform designed for building robots, model vehicles, mechanical systems, and STEM projects. Manufactured from durable ABS plastic, the plate features a regular pattern of 3mm diameter holes spaced at 5mm intervals, providing students with a flexible base for mounting gearboxes, motors, wheels, brackets, and other Tamiya Educational Construction components.
The pre-drilled hole pattern allows components to be attached using screws without students needing to drill a new chassis for every project. This makes the Universal Plate particularly useful in the classroom, where projects can be assembled, tested, modified, dismantled, and reused. Students can easily reposition components as their design develops, encouraging experimentation and iterative design.
When combined with Tamiya gearboxes, wheels, tracks, ball casters, and other construction components, the T70098 provides an excellent starting point for building anything from a simple motorised vehicle to a programmable robotic system.

What’s Included

• Tamiya Universal Plate components
• Assembly hardware supplied with the set

A Flexible Base for Student Projects

The regular mounting-hole pattern is one of the most useful features of the T70098 Universal Plate. Rather than permanently fixing components into one position, students can experiment with different layouts and reposition parts as their project develops.
Components can be arranged to investigate:
• Motor and gearbox position
• Wheel spacing
• Track width
• Weight distribution
• Sensor positioning
• Battery location
• Chassis balance
• Mechanical linkages
This makes the Universal Plate particularly useful for the design, build, test, evaluate, and improve process used in engineering and technology projects.

Build a Robot Chassis

The T70098 can be used as the main chassis for a simple wheeled or tracked robot.
A typical project could combine:
• T70098 Universal Plate Set – chassis
• T70168 Double Gearbox – independent left/right motor drive
• T70101 Truck Tire Set – wheels
• T70144 Ball Caster Set – chassis support
• Motor controller
• PICAXE or Arduino-compatible microcontroller
• Sensors
• Suitable power supply
Alternatively, the plate can be combined with the T70100 Track and Wheel Set to create a tracked robotic vehicle.

3mm Holes at 5mm Intervals

The plate features 3mm diameter holes positioned at 5mm intervals. This regular grid provides numerous mounting positions for compatible mechanical components.
Students can use the hole pattern to plan component placement and make changes without having to manufacture a completely new chassis.
This is particularly valuable during prototyping because students can test one configuration, evaluate its performance, and then move components to improve the design.
