Mechanics and Construction / Robot arm torque - reg
« Last post by Robo shankar on December 07, 2017, 05:48:31 AM »
Hi,

I have found the online robot arm calculator from your website. The link is mentioned below

"http://www.societyofrobots.com/robot_arm_calculator.shtml".

In this calculator, torque of M0 motor is less than the torque of M1 motor When i am giving same acceleration for the both motors. But all the arm weights & motor weights is acting on the M0 motor. So I think that the torque for M0 motor should be higher than the M1 motor. But it is not like that in calculator.

Is there any principle behind this ? or any formula to find out the torque of the M0 motor ?

Misc / New PWM Meter & Low Voltage Cutoff Switch
« Last post by ServoCity on November 30, 2017, 03:54:54 PM »
PWM Meter - $19.99
https://www.servocity.com/pwm-meter
Need to know what PWM signal your receiver, robot or servo controller is sending? Simply plug in our PWM Meter to see a readout of the PWM signal in microseconds (?sec). If you wish to pass that signal on to your servo or device, just plug into the other set of header row pins.

Low Voltage Cutoff Switch - $19.99
https://www.servocity.com/low-voltage-cutoff-switch
It's important to protect your LiPo batteries from being drained below 3V/cell and our Low Voltage Cutoff Switch does just that. This switch has 3 modes; 1S, 2S or 3S and it simply passes the voltage on from the battery to the load (motor controller, ESC, servo controller, light, etc.) until the battery meets the cutoff voltage.

Whether you are powering a microcomputer like a Raspberry Pi, a microcontroller like an Arduino or an RC vehicle, our Low Voltage Cutoff Switch takes away one of the main challenges of working with LiPo batteries.

Mechanics and Construction / Robotic Hand
« Last post by icecapsule on November 23, 2017, 06:34:44 AM »
Hi, I'm planning on making a robotic hand for an art exhibition. From looking online, it seems this tutorial is laid out pretty well and should be suitable for my project;
However, I want the movement of the robot to be from code rather than from the glove, is this possible? The type of movement I want is pretty basic (I think!) it's just small random twitches and glitches, nothing specific. Thanks, Claire

Electronics / Re: 2 x 18v drill motors & Trigger for speed control
« Last post by Gasman on November 22, 2017, 01:23:18 AM »
So I have solved the problem I think. I used another trigger without a Mosfet and pumped 24v through both motors. runs at a crawl no excessive heat from switch or motors. Not entirely sure what the issue was , at a guess I'm gonna say it was the low voltage.

Misc / Robotics Project, Workers, Students, teachers wanted
« Last post by Duin on November 20, 2017, 12:34:10 PM »
I am a retired business man in Holland who will visit India this winter. I have a project to build a robot.
I am looking for someone who would like to work part time to help build a robot, and is knowledgeable in at least some specialties related to robotics.

My long term goal is to build a kind of Boston Dynamics Spot Mini  but with soft muscles and fur.
This is the sort of robot that could be used both as a toy, a sophisticated personal companion pet for anyone, and a companion for elderly.
A longer term goal, for later development, is to build a lifelike humanoid robot.

I do not expect that present technology is sufficient to do this immediately, but clearly the technology is getting close, and I want to begin now to experiment and design, taking small steps towards these goals.

I believe, however, that India is especially well suited for this sort of development, and I will visit India for a month or two this winter to talk to people like yourselves about this.
Initially I will be looking for robotics engineers, professors, or students who would be interested in part time work, both to advise me, and to begin some development.

This  might, or might not, become a business, a working startup company. I will support some limited costs, and pay wages to learn and begin designing and building these robots.
If I hire someone, it would be part time, no fixed hours, and an experimental project..

It will require some significant knowledge, or interest in artificial intelligence, the new ?soft muscle? technologies,  robot vision, walking, etc, and general experience in robotic engineering.

This is not a quick project. It may be spread out over several years as these new technologies are developed. The persons I work with do not have to be experienced in all these fields. One may specialise in only one of these areas. I would be happy to deal with more than one person, with different persons in different specialties and in different locations in India as it is a complex project.

Please advise me if you could help in any way, either directly, or by referring me to others.

If you know someone else who might be interested, or can advise me how to find persons to help me, please advise.
Thank you,
Dale Quam
