JEVAROO

The future of home care robotics

Jevaroo is a 8 degree of freedom robotic arm on a movable platform. Jevaroo empowers people with a disability and seniors and saves carers’ travel time and costs.

No boundaries

With Jevaroo's 8 degrees of freedom, Jevaroo can travel forwards and backwards, side-to-side, and rotate on the spot.  Jevaroo's neck allows for its limb to be angled at different heights, and Jevaroo's limb motors allow for the arm to adjust and hone in carefully to interact with objects.

Benefits

Independence

Allows you to do tasks for yourself, by yourself, giving you freedom and independence in your home and in your life

Higher Quality Of Life

Reduce informal care needed, leading to greater quality of life for everyone in the household

Save Carer Time

Reduce formal carer hours needed, by being able to do simple tasks yourself, freeing your carer up to tackle bigger tasks

Jevaroo can perform many tasks.

Jevaroo’s has eight degree of freedom which allows it to perform a wide range of complex movements. This further imply Jevaroo’s versatility making it possible to cater for various tasks that the users have in mind. Jevaroo’s  movement constraint are summarised as follows.

Jevaroo's limb is modeled after a human arm, with a wrist and an elbow
Wrist movement range allows for Jevaroo's hand to be position

Neck movement range of 25cm.
Maximum horizontal reach of 110cm.
Maximum vertical reach of 170cm.
Maximum effective grip diameter of 15cm.
Maximum hand rotation range of 15 degrees above horizontal and 45 degrees below horizontal
Maximum elbow rotation range of 15 degrees above horizontal and 50 degrees below horizontal
Maximum arm rotation range of 45 degrees above horizontal and 50 degrees below horizontal.

Screw-type linear actuators provide a significant amount of lifting force
Twin linear actuators can be operated independantly, allowing Jevaroo to reach up to a high shelf or down low to the floor

Moving back and foward

The base uses omni wheels, giving it holonomic drive, meaning it can move backwards and forwards;  sideways like a crab, and rotate on the spot.  
The base can travel forwards and backwards for an unlimited amount of time.
The base can travel sideways - both ways for an unlimited amount of time.
The base can rotate on the spot, with no turning circle

Loading

Jevaroo is able to lift a relatively heavy load. Although it is expected that the grip area of the robot, failure loading at other components of the robot has been optimised to safeguard against failure due to unorthodox loading configuration

Maximum Grip Strength of 2.5 Nm.
Maximum Lift on Closest angle of 2.32 Kg
Maximum Lift on Furthest angle of 1.32 Kg

Jevaroo is strong enough to lift weights even when it's arm is extended, up to 1.32kg

Maximum Shoulder Loading of 9.6 Kg
Maximum Elbow Loading of 1.59 Kg
Maximum Arm Loading of 4.84 Kg
Maximum Hand Loading of 2.25 Kg
Maximum Wrist Loading of 0.33 Kg

Jevaroo can lift up to 2.32kg when lifting from close to the base
Rotary potentiometers are used to provide precise rotational position to Jevaroo's software

Moving Speed

Jevaroo movement speed has been designed to enable it to complete the tasks it is meant to do while maintaining prime emphasis on safety of operation and ease of use. The following isdata regarding the movements of its components.

Base maximum forward and backward speed of 0.2m/s or 12m/m.
Base maximum rotation speed of 20 rev/min.
Hand joint rotation speed of 7.5 rev/min.
Elbow joint rotation speed of 1.57 rev/min.
Shoulder speed of 0.01875 m/s
Arm rotation speed of 1.38 rev/min
Wrist rotation speed of 3.34 rev/min

Jevaroo's three-omniwheel configuration allows it to rotate perfectly on the spot
Jevaroo drives at a safe speed

Miscellaneous

Battery Life

Jevaroo’s batteries are rechargeable and are capable of powering Jevaroo for 8 hours before needing to be recharged.

Mass

Jevaroo weighs 45 Kg.

Control Interface

Jevaroo may be controlled by a person in the same room over Bluetooth or by a carer in another location via wifi in order to do chores or personal tasks around the home or away from home - getting drinks, opening doors, and carrying items.

Remotely Controlled

From your computer
anywhere in the world

X-box Controller

Like a video game -
guiding Jevaroo is
fun and intuitive

Photos

If you are thirsty, Jevaroo can serve you a drink

Independent twin linear actuators allow Jevaroo to pick up things from the floor and put them into the bin

Heavy doors can be pushed open by Jevaroo due to the strength of it's drive motors

360 degree hand and base rotation combine to allow Jevaroo to grip a door and swing it shut

Jevaroo is stable enough to pour a glass of water without spilling

A full drink is easily within Jevaroo's loading limits

Testimonials

Tanya, 50s (Carer)

"These will be great for those clients who don’t want that 24/7 care. We’ve got quite a few clients who they just get sick of someone always having to be there they want to be alone - Those days (of being alone) are gone for them."

Peter, 40s (Quadriplegic Association staff)

"It's definitely a big improvement.  Now it's time to use your imagination. You can use it around the house - They're quite ideal to put in the house or your office to start to explore it more and more."

Josh, 30s (Paralympic gold medallist)

"I was always trying to steal my brother's chocolate, so it's good to know this can reach to that height - I used to use the broom and knock is down and catch it!"

History of Jevaroo

We filmed a documentary with Al Jazeera English while we were in the process of creating Jevaroo.
