The new family of precision drives offers higher torque density than competing strain wave gearing with no compromise in performance. The unique patented design utilizes a series of cam-driven blocks that engage over 80% of the output ring surface area at all times. This design distributes load stresses over a much larger surface area, permitting the Motus M-DRIVE to deliver much higher torque per unit size and volume than competing strain wave drives.
Motus Labs identified an opportunity to disrupt the robotic drive market.
All articulated robots have multiple joints built with actuators – a combination of motors and gears, that control positioning and acceleration on various axes. The transmissions or drives are the most critical, differentiating and expensive component, yet still have performance limitations.
Critical part – High cost – Limited performance – all the makings for a breakthrough invention!
A common challenge faced by the robotic suppliers is the high cost and limited performance of the actuators/gear drives.
A Service robot performs useful tasks outside the area of industrial automation such as agriculture, medical, logistics, construction & inspection.
The fast-growing, Cobot robot market builds smaller robots that often work alongside humans. The robots can ‘learn’ on the job and have other characteristics unique to working with humans.
Traditional, large industrial articulated robots are more expensive to build and often replace humans.
New design results in higher torque density, zero backlash, superior torsional stiffness & positional accuracy
The M-DRIVE design can be built with lighter materials such as aluminum or even plastic, resulting in dramatically lower weight actuators.
The improved cohesion of mating surfaces eliminates the elasticity found in conventional drives that slow down and destabilize robots.
The M-DRIVE design eliminates the need for special alloys and complex manufacturing processes, contributing to an overall cost reduction of a robot.
Provides high torque with less weight, due to the M-DRIVE’s lighter materials.
The unique design provides greater position accuracy, no hysteresis loss, and zero backlash.
The M-DRIVE provides 20-30% higher power efficiency than competing strain wave gearing.
Robotic drive uses mating surfaces instead of gear teeth – resulting in a lighter, faster & more accurate robot.
A robot actuator must be strong, precise, and lightweight, resulting in a costly design.
Strain wave and cycloidal designs are still using gear technology that has many limitations.
Today’s robots require high torque, high precision, low weight and a controlled rate of motion. Current gear-drive designs need to meet these requirements and rely on expensive, special alloys and high-precision manufacturing processes.
We know the M-DRIVE can significantly impact the robotic industry due to the innovative design and all-around better efficiencies. Just imagine if the cost of building a robot could be cut up to 50%, yet it was stronger, more precise and lighter. Various industries would have the ability to use robots in more applications and bring them to market faster and cheaper.
