What is Robot Shop doing to make the Lynxmotion Robotic Arms work through the power supply issue. We bought 30 of them for our PLTW classrooms because you were the recommended vendor. When we get them none of them work because the power supply is inadequate. I am not sure why Robot Shop is selling a robotic arm that they know is not going to work. All 30 of them have the same problem. The bottom servo pulls to much amperage and shuts down the entire system. The suggested fix in your forums is to wire in seperate power to the larger servo, but no power supplies or wiring is provided for this!!! We should not have to pay more money to make a defective design work. I need to know what the plan is to provide both a solution and the equipment needed to make the product work. Otherwise I will call and return all 30 arms and look for a different source.
We are replacing all defective power supplies and you will not be responsible for covering any cost to ship back the defective unit or to send the new unit to you. We greatly apologize for any inconvenience and request that you contact us via the support center with your order number or invoice number and a link to this topic, and we will resolve the issue ASAP.
Excellent. Thank-You.
I am in the same boat. I purchased 10 of these arm kits and cannot get any of them to work. Once I disconnected the large servo at the base of the arm, it functioned correctly. We are a PLTW school and need a remedy for this problem because the arm cannot work as intended with the bottom servo operating.
Same solution:
Assuming you have a 6V, 3A power supply, we are replacing all defective power supplies and you will not be responsible for covering any cost to ship back the defective unit or to send the new unit to you. We greatly apologize for any inconvenience and request that you contact us via the support center with your order number or invoice number and a link to this topic, and we will resolve the issue ASAP.
They will send you new power supplies if you call with your invoice number. They arrive in a couple of days and work great.
