Anyone can program this cheap robot arm in just 15 minutes

Eva was designed with small-scale production in mind. It&#;s light enough to carry in a backpack, and compact enough to sit on a desk. More important, it&#;s designed to be easy to use. Its software can run on any device and includes drag-and-drop functions. Automata says that anyone can learn to program it in just 15 minutes with minimal or no training.

That&#;s important, because the biggest barrier for small and medium-size companies isn&#;t just the one-time cost of the kit. It&#;s also the need to hire someone to maintain and program it, says Julie Shah, an associate professor at MIT&#;s Computer Science and Artificial Intelligence Lab.

The relatively low initial cost should be attractive for smaller businesses, too, the firm hopes. It managed to get the price down by bypassing traditional production routes, according to founders Mostafa ElSayed and Suryansh Chandra. They have spent the past four years designing, tweaking, and fine-tuning the robot.

Rather than buying components off the shelf from one of the two potential external suppliers, they designed the robot&#;s gearbox from scratch, choosing cheaper parts, the pair say. There will be a necessary trade-off between cost and precision, but Automata hopes that its robot will fill a low-cost niche for its customers that hasn&#;t been filled before.

Most of these customers are small and midsize manufacturers from a range of established industries, including metal fabrication, electronics, pharmaceuticals, and packaging. Eva is replacing simple, repetitive manual tasks such as product testing, placing things on conveyor belts, sorting, dispensing, and inspection, for example. One customer is using Eva to test smartphones.

By stripping out unnecessary functionality, Automata says, it has managed to make a device 80% equal in precision and performance to world-leading robots from big firms such as  Kuka or Yasakawa, but at roughly 20% of the cost.

But robotics is a tough field to crack. Boston-based startup Rethink Robotics had to close last October, despite its impressively safe and easy-to-use machines Sawyer and Baxter. It will be hard to survive without access to a significant sales and distribution network, warns Henrik Christensen, director of the Contextual Robotics Institute at UC San Diego. Automata could also be at risk if one of the big tech companies decides to muscle in on the territory.

Still, Automata think its appeal to smaller firms can help it succeed where others have failed.

&#;Automata could potentially have a big impact pushing automation and robotics through to smaller companies,&#; Shah says. &#;It&#;s very exciting.&#;

DIY Robotic Arm : 8 Steps (with Pictures)

The torque law is T=F.L and the affecting force on the robotic arm is its weight W=m.g

but when buying the motors you will find the torque unit in (kg.cm) so the law used in calculate the torque is T=m.L ,where m is the mass the part and L is the perpendicular distance from rotation axis of motor to center of gravity of the body.

To determine the required torque we choose the critical case which the weight of the body causes the biggest torque and choose motor equal to this torque, and it's preferred to give safety factor equal to 1.5 for smooth motion without vibrations.

The critical case is in horizontal position that gives the biggest perpendicular distance as shown in picture 1 and it's obvious that L3 is the biggest distance in horizontal position.

The robot arm must be in this case when calculating the torque of motors as shown in picture 2

Thenwe start to calculate the torque at each motor like picture 3 and the equations of this picture is:

T1=L1.A1+0.5L1.W1

T2=L5.A1+L4.W1+L3.A2+L6.W2

In this method we consider each motor as lumped mass and its weight is A and perpendicular distance is L , so the torque caused by motor is T=L.A

And for the torque caused by each link that has length L and mass W is T=0.5L.W , and the final torque for motor is the sum of two torques and everything that preceding of weights ( T=L.A+0.5L.W+........)

The final results of motors torques when using the wood for this design is as shown in picture 4.
