- Gear ratio: 65.5:1 and 4 encoders
- Remote Visualization
- Designed for university, college, and high school programs engaged in real-world robotic research
- Increased Payload Capacity
The SMP Four Encoder Version is a research quality Surface Mobility Platform designed for university, college, and high school programs engaged in real-world robotic research. This research robot was developed using mobile platform technology created by GEARS Educational Systems. The structural components of the GEARS-SMP chassis are custom manufactured from black anodized 6061-T6 aluminum alloy tubing suspended on a 1/2'' diameter titanium alloy main axle. The chassis of the GEARS-SMP surface Mobility Platform is scalable and easily customized so you can create mission specific configurations and accommodate various payload requirements.
The body of the chassis remains extremely stable while roving over rough terrain. This makes the GEARS-SMP and ideal camera platform or reconnaissance vehicle. The GEARS-SMP can be broken down and field stripped in less than 3 minutes for easy transportation by car, boat, or plane.
The GEARS-SMP is a robotic engineering product intended for educational programs that wish to integrate the following robotic technologies:
- Sensors
- Remote Visualization
- GPS/Navigation Strategies
- Alternative Energy systems
- Autonomous Control
- Extended Mission Capabilities
- Increased Payload Capacity

Structural Components
The GEARS-SMP chassis is scalable and customizable. Using GEARS-SMP basic connectors and off the shelf 1-1/4'' Aluminum square tubing, it is possible to create mission specific custom chassis configurations. It is possible to create three different configurations just by ordering different connectors.
Note: DC brush motors can be driven at voltages greater or lesser than the specified winding voltage. Greater voltage results in faster speeds, but generates proportionally higher currents and heat.
The 65.5:1 Gear ratio provides a usable compromise between speed, torque, and current draw. Observed performance: 2 fps at 12 volts/ Max continuous tractive force is 8 lbs @ 2.25 amperes per wheel.This motor is particularly well suited to off-road use.
The 19.7:1 Gear ratio driven by a 9.55 volt armature provides high speed with limited torque. Observed performance: 6+ fps at 12 volts/ Max continuous tractive force is 1 lbs @ 2.25 amperes per wheel. This is a competition motor option and can be used to navigate greater distances in less time over flat terrain. This motor option is not well suited for off-road use.
