These shifting transmissions are designed for mobile robots weighing 50-250 pounds. There are significant benefits to having a shifting transmission on a robot this size.
- A top speed can be attained by shifting into high gear. This top speed can be set to be optimized for a speed that is good for long distance moves (15+ feet), but not for short, high acceleration moves.
- A high torque can be attained by shifting into low gear. This low speed can be optimized so that the robot motors do not stall out while in a pushing contest or in a high-torque situation.
- When set to low gear, the robot is more controllable, and the driver can make more precise moves to place the robot into position.
- When set to low gear, the motors of the robot draw less current to move into desired positions. Often, after a couple of minutes in high gear, a robot's motors may be pulling high amounts of current, and the need to shift to low gear will be beneficial.
